Before TYMKOVICH, McKAY, and MATHESON, Circuit Judges.


MATHESON, Circuit Judge.


       This appeal consolidates two cases about United States Forest Service (the “Forest

Service”) actions in the Black Hills National Forest (“BHNF”), which straddles the

Wyoming and South Dakota border.

       The Appellants,1 led by Biodiversity Conservation Alliance, are non-profit entities

(collectively, “Biodiversity”) interested in species and habitat protection in the BHNF.

The Appellees2 are the Forest Service and several of its officials tasked with managing

the BHNF. Intervenors-Appellees3 are state and county governments and private groups

concerned with how management of the BHNF affects nearby private land, state and

county citizens, and visitors.


       1
        Biodiversity Conservation Alliance, Western Watersheds Project, Native
Ecosystems Council, and Prairie Hills Audubon Society. Brian Brademeyer, a resident of
the BHNF, is also a petitioner.
       2
       The U.S. Forest Service; the Chief of the U.S. Forest Service, Tom Tidwell; the
Regional Forester for the Rocky Mountain Region, Daniel Jiron; and the Supervisor for
the BHNF, Craig Bobizen.
       3
          The State of Wyoming; the State of South Dakota; the Secretary of the South
Dakota Department of Agriculture, Lucas Lentsch; and the South Dakota counties of
Meade County, Lawrence County, and Pennington County. Also included are two non-
profit groups—the Black Hills Forest Resource Association and the Black Hills Regional
Multiple Use Coalition.



                                            -1-
       Biodiversity sued the Forest Service regarding the BHNF in two separate

proceedings. First, in the United States Federal District Court for the District of

Wyoming, Biodiversity claimed the Forest Service had failed to comply with various

federal statutes and regulations. The court denied Biodiversity’s petition for review.

       Second, in the United States Federal District Court for the District of Colorado,

Biodiversity moved for relief, arguing the Forest Service had violated a settlement

agreement. The court dismissed that motion.

       Biodiversity appeals. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm

both the Wyoming and Colorado federal district courts.

                                   I. BACKGROUND

       We describe relevant statutes and regulations, summarize the factual and

procedural history of the two cases, and then turn to our analysis.

                         A. Relevant Statutes and Regulations

       Two sources of statutory and regulatory law govern this case: (1) the National

Forest Management Act of 1976 (“NFMA”); (2) the National Environmental Protection

Act of 1969 (“NEPA”); and both acts’ implementing regulations. We provide a short

overview here and more details during our analysis.

1. National Forest Management Act

       The Forest Service—a United States Department of Agriculture (“USDA”)

agency—manages the national forest system. NFMA requires the Forest Service to

manage forests using a two-step process. See 16 U.S.C §§ 1600-1614. First, the Forest

Service must develop a Land and Resource Management Plan (“forest plan”) for each


                                             -2-
national forest unit. Second, it must implement the forest plan through site-specific

projects. 16 U.S.C. § 1604(a) & (i); see also Silverton Snowmobile Club v. USFS, 433

F.3d 772, 785 (10th Cir. 2006).

       Forest plans must “provide for diversity of plant and animal communities based on

the suitability and capability of the specific land area . . . .” 16 U.S.C. § 1604(g)(3)(B);

see also Utah Envtl. Cong. v. Russell, 518 F.3d 817, 821 (10th Cir. 2008). Implementing

regulations provide standards and guidelines to create a forest plan and approve any

accompanying site-specific projects. See 16 U.S.C. § 1604(g); Utah Envtl. Cong. v.

Bosworth, 443 F.3d 732, 737 (10th Cir. 2006). When we review a challenge to a forest

plan or a site-specific project, we must determine whether the plan or the project meets

NFMA and NFMA’s implementing regulations. See Utah Envtl. Cong. v. Troyer, 479

F.3d 1269, 1272 (10th Cir. 2007).

       The NFMA regulations have been amended numerous times. We focus on the

1982 amendment (the “1982 Rule”) and the 2005 amendment (the “2005 Rule”). See 47

Fed. Reg. 43,026 (Sept. 30, 1982) (codified at 36 C.F.R. §§ 219.1-219.29 (1982)); 70

Fed. Reg. 1023 (Jan. 5, 2005) (codified at 36 C.F.R. §§ 219.1-219.16 (2005)). Although

more recent rules have superseded both of those rules, the 1982 and 2005 versions are

pertinent to this case.

       a. The 1982 Rule

       The 1982 Rule required the Forest Service to promote the diversity of species by

maintaining “viable populations of existing native and desired” plants and animals. 36




                                              -3-
C.F.R. § 219.19 (1982).4 This “viability mandate” required that each species’ population

and habitat be abundant and well-distributed enough to safeguard its continued existence.

See id.

          The 1982 Rule allowed the Forest Service to comply with the viability mandate by

monitoring a selected group of “Management Indicator Species” (“MIS”). Id.

§ 219.19(a)(1). MIS are “[p]lant or animal species . . . that are used to monitor the effects

of planned management activities on populations of wildlife and fish, including those that

are socially or economically important.” Phase II Amendment Glossary, App. at 2338.

Thus, the MIS served as proxies for other species’ health in the forest. See 36 C.F.R.

§ 219.19(a)(1) (1982) (“These species shall be selected because their population changes

are believed to indicate the effects of management activities.”); Forest Guardians v.

USFS, 641 F.3d 423, 427 (10th Cir. 2011) (per curiam) (comparing the MIS to canaries

used in coal mines to detect dangerous levels of poisonous gas). In addition to ensuring

sufficient habitat for the MIS, the 1982 Rule required the Forest Service to “gather

quantitative data on actual MIS populations . . . .” See Utah Envtl. Cong. v. Bosworth,

372 F.3d 1219, 1227 (10th Cir. 2004).

          Under the 1982 Rule, the Forest Service measured its success at maintaining

“viable populations” of plants and animals in the forest—thereby meeting the NFMA


          4
        Although the 1982 Rule’s viability mandate stated it applied only to “vertebrate
species,” id. § 219.19, USDA departmental regulations expanded § 219.19’s viability
mandate to include invertebrate and plant species. USDA Fish and Wildlife Policy, Dep’t
Reg. 9500-4, August 22, 1983.



                                              -4-
mandate to “provide for diversity”—by monitoring the actual populations of the MIS in

the forest.

       One of the issues in this case is how to interpret and apply § 219.19’s viability

mandate.

       b. The 2005 Rule and the 2005 Modification of the 1982 Rule

       The Forest Service promulgated several rules that superseded the 1982 Rule. One

was the 2005 Rule. See 36 C.F.R. §§ 219.1-219.16 (2005); see also 70 Fed. Reg. 1023

(Jan. 5, 2005) (promulgating the 2005 Rule). But the 1982 Rule survived under certain

circumstances. The 2005 Rule permitted the Forest Service to continue using the 1982

Rule for forest plans, such as the BHNF’s, that were already following the 1982 Rule, but

with one narrow modification (the “2005 Modification”): “[T]he [Forest Service] may

comply with any obligations relating to [MIS] by considering data and analysis relating

to habitat unless the plan specifically requires population monitoring or population

surveys for the species.” 36 C.F.R. § 219.14(f) (2005).

       One of the issues in this case is what effect the 2005 Modification had on

§ 219.19’s viability mandate.

2. National Environmental Protection Act

       In addition to NFMA, the Forest Service must also comply with NEPA, see 42

U.S.C. §§ 4321-4347. NEPA established a national policy to “promote the understanding

of the ecological systems and natural resources important to the United States,” and

thereby “reduce or eliminate environmental damage.” Dep’t of Transp. v. Pub. Citizen,

541 U.S. 752, 756 (2004) (quotations omitted). NEPA does not mandate particular


                                             -5-
results or create substantive limits—rather, it “imposes only procedural requirements on

federal agencies with a particular focus on requiring agencies to undertake analyses of the

environmental impact of their proposals and actions.” Id. at 756-57.

       Broadly speaking, before taking a “major Federal action significantly affecting the

quality of the human environment,” 42 U.S.C. § 4332(2)(C), NEPA requires agencies to

prepare an environmental impact statement (“EIS”), which determines how much a

proposed agency action will affect the environment, 40 C.F.R. § 1502.1-1502.25. Not all

agency actions are subject to this requirement5—various regulations “guide federal

agencies in determining what actions” must be accompanied by an EIS. Dep’t of

Transp., 541 U.S. at 757; see also 40 C.F.R. §§ 1500.1 to 1508.08. For example, an

agency may instead, in certain circumstances, prepare an environmental assessment

(“EA”), 40 C.F.R. § 1508.9, which determines whether a proposed action would require a

full EIS, 40 C.F.R. § 1501.4(a) & (b),6 or a categorical exclusion (“CE”), which states the




       5
         Compliance with NEPA is required . . . only if the federal government’s
involvement in a project constitutes major federal action,” Ross v. Fed. Highway Admin.,
162 F.3d 1046, 1051 (10th Cir. 1998) (quotations omitted), meaning one that
significantly affects the quality of the human environment, as determined by considering
the “context and intensity” of the proposed action. 40 C.F.R. § 1508.27.
       6
        If the EA concludes the action could significantly affect the environment, the
agency action must then prepare an EIS; if not, the agency issues a Finding of No
Significant Impact (“FONSI”), and no further NEPA analysis is required. See id.
§§ 1501.4(e), 1508.13; Dep’t of Transp., 541 U.S. at 757–58.



                                            -6-
proposed action falls within a category of actions that do not have a significant effect on

the environment, 40 C.F.R. § 1508.4. See Utah Envtl. Cong. v. Russell, 518 F.3d at 821.7

       Because a forest plan governs the majority of the Forest Service’s actions in

managing a forest, “[t]he creation of a forest plan” and “[a]ny significant amendments”

require “the preparation of an EIS.” Silverton Snowmobile Club, 433 F.3d at 785

(quotations omitted). In this appeal we consider an EIS issued as part of a forest plan

revision called the “Phase II Amendment.” Especially relevant are two requirements for

preparing an EIS: (a) the “no action” alternative and (b) the “hard look.”

       a. The “reasonable range” of alternatives requirement and the “no action”
          alternative requirement

       Under NEPA, an EIS must contain a detailed statement regarding “alternatives to

the proposed action.” 42 U.S.C. § 4332(2)(C)(iii). The agency must “[r]igorously

explore and objectively evaluate all reasonable alternatives” for the proposed action in

response to a “specif[ied] underlying purpose and need.” 40 C.F.R. §§ 1502.13,

1502.14(a). The range of “reasonable alternatives” must at least include the alternative of

taking “no action,” 40 C.F.R. § 1502.14(d), which we have described as “the option of

         NEPA regulations also allow an agency to issue a CE when actions are deemed
not to “individually or cumulatively have a significant effect on the human
environment . . . .” 40 C.F.R. § 1508.4. The USDA has categorically excluded various
activities, such as issuing budget proposals, enforcing civil and criminal law, and
conducting research. See 7 C.F.R. § 1b.3(a). Additionally, the Forest Service has
categorically excluded activities such as closing a forest area during extreme fire danger,
purchasing land, and repairing or maintaining roads. See 36 C.F.R. § 220.6(d).

Mgmt., 565 F.3d 683, 690 (10th Cir. 2009).

      b. The “hard look” requirement

      An EIS must consider “any adverse environmental effects.” 42 U.S.C.

§ 4332(2)(C)(iii). This review cannot be superficial—agencies must “take a ‘hard look’

at the environmental consequences of proposed actions utilizing public comment and the

best available scientific information.” Colorado Envtl. Coal. v. Dombeck, 185 F.3d 1162,

1171 (10th Cir. 1999); see also Robertson v. Methow Valley Citizens Council, 490 U.S.

332, 350 (1989). The “hard look” standard ensures the “agency did a careful job at fact

gathering and otherwise supporting its position.” New Mexico ex rel. Richardson, 565

F.3d at 704 (quotations omitted).

      The BHNF covers roughly 1.2 million acres of land straddling the Wyoming and

South Dakota border. 2005 Final EIS, App. at 1154-55. Often referred to as “an island

in the prairie,” the BHNF features an isolated mountain range surrounded by mid-western

prairies. 2005 Final EIS, App. at 1164; see also 1997 Final EIS, App. at 270. The BHNF

includes many plants and animals from four ecological zones: the Rocky Mountains, the

diversity in the area exceeds many other mountain ranges. See 1997 Final EIS, App. at

277.

       Biodiversity challenges certain Forest Service actions concerning the BHNF. We

provide an overview of the facts and procedural background here, and then add details

during our analysis.

1. The 1997 Forest Plan: Promulgation, Challenge, and Forest Service Response

       a. Promulgation and Biodiversity’s challenge

       After NFMA took effect in 1976, the Forest Service created a forest plan to

manage the BHNF and used it for roughly a decade. 1997 Final EIS, App. at 257. In

1992, the Forest Service decided to revise the forest plan. 1997 Final EIS, App. at 260.

After years of drafting, surveying, and public notice and comment-making, the Forest

Service issued its 1997 Record of Decision, Final EIS, and Revised Forest Plan

(collectively, “1997 Forest Plan”). The 1982 Rule governed the preparation of the 1997

Forest Plan. See, e.g., 1997 Record of Decision, App. at 292-93, 298-99, 305.9

       Biodiversity challenged the 1997 Forest Plan in an administrative proceeding,

arguing it did not comply with NFMA and NEPA.



       9
        The 1997 Forest Plan does not explicitly state it relied on the 1982 Rule, but
because no other rule existed until 2000, we determine the 1997 Plan relied on the 1982
Rule. The parties do not argue otherwise.



                                            -9-
      b. Forest Service response: the Chief’s 1999 Decision

      In 1999, the Chief of the Forest Service (“Chief”) decided Biodiversity’s

administrative appeal (“Chief’s 1999 Decision”). The Chief examined “27 key issues”

and determined that, although most of the 1997 Forest Plan complied with NFMA and

NEPA, parts of the Plan fell short. Chief’s 1999 Decision, App. at 2462. He identified

four “primary deficiencies of concern”: (1) “[v]iability determinations for some species,”

(2) “[s]tandards and guidelines to maintain viability of some species,” (3) “[m]anagement

indicator species (MIS) requirements,” and (4) “[m]onitoring direction for some sensitive

species.” Id. Within the general framework of those four primary deficiencies, the Chief

then discussed more specific shortcomings, including four under NFMA and one under

NEPA.10

               i. NFMA Shortcomings

                      1) Insufficient northern goshawk protections

      The Chief found the 1997 Forest Plan lacked sufficient objectives to protect

northern goshawk populations.11 Without adequate objectives, such as designating

specific areas where goshawks can live after the fledgling stage, the 1997 Forest Plan did

not meet NFMA’s viability mandate because the viability of the northern goshawk could


      10
         The Chief identified other deficiencies in the 1997 Forest Plan, but we do not
describe them here because they are not at issue in this case. See, e.g., Chief’s 1999
Decision, App. at 2466-67, 2527 (stating the 1997 Forest Plan failed to include an aquatic
species as MIS).
      11
           A northern goshawk is a medium-size bird of prey.



                                            - 10 -
not be assessed. Id. at 2507-08.

                     2) Insufficient snag density

       The Chief said the 1997 Forest Plan failed to meet NFMA’s requirement to ensure

the viability of species because it did not provide enough “snag” habitat. Id. at 2503-05.

       A “snag” refers to a dead but still-standing tree or portion of a tree. Many species

depend on snags for food and shelter. See 2005 Revised Forest Plan Glossary, App. at

2306 (defining “Cavity Nesting Species”), 2363 (defining “Snag”).

                     3) Insufficient objectives for Emphasis Species

       The Chief found the 1997 Forest Plan failed to state adequate objectives for

certain Emphasis Species. The Forest Service uses the term “Emphasis Species” as an

umbrella term encompassing various categories of species that receive particular

management attention, including MIS,12 “Threatened and Endangered Species,”13

“Sensitive Species,”14 and “Species of Local Concern.”15 2005 Final EIS, App. at 1282.



       12
         As noted above, under the 1982 Rule the Forest Service must monitor MIS
populations to gauge the forest’s health. 36 C.F.R. § 219.19(a)(1) (1982).
       13
        These are species protected by the Endangered Species Act of 1973. See 16
U.S.C. §§ 1531-1544; 50 C.F.R. §§ 17.11-17.12 (listing species).
       14
         Sensitive Species are plant and animal species “for which population viability is
a concern, as evidenced by significant current or predicted downward trends” in
population or habitat. Phase II Amendment Glossary, App. at 2361; see also id. at 1282;
Forest Service Manual § 2672.11 (Sensitive Species Evaluation Criteria).
       15
          In the Rocky Mountain Region—the administrative region applicable to the
BHNF—the Forest Service defines a Species of Local Concern as one that does not meet
the criteria for Sensitive Species, but faces decline or is an important component of
diversity in a local area. See 2005 Final EIS, App. at 1282; Allen et al., Forest Service,
                                                                              Continued . . .

                                            - 11 -
       The Chief determined the 1997 Forest Plan did not meet NFMA’s viability

mandate because it lacked MIS data, did not adequately explain why it selected certain

species for inclusion as MIS, and omitted monitoring objectives. Without the foregoing,

the Forest Service could not properly monitor MIS populations. Chief’s 1999 Decision,

App. at 2510-12.

       The Chief also found that without adequate Sensitive Species objectives, the 1997

Forest Plan did not meet NFMA’s viability mandate to ensure Sensitive Species would

not decline beyond unrecoverable levels. Id. at 2505-07, 2510-12.

                     4) Insufficient protections for sensitive plant and animal species

       Finally, the Chief found the 1997 Forest Plan inadequately protected sensitive

“riparian and aquatic species and their habitats in areas with ongoing livestock grazing.”

Id. at 2463. The Chief was particularly concerned about the viability of two sensitive

snail species and adequately protecting Research Natural Areas (“RNAs”)16 and

          RNAs are “relatively pristine areas that represent a wide range of natural
variability within important natural ecosystems and environments . . . and areas that have
special or unique characteristics of scientific importance.” 2005 Revised Forest Plan,
App. at 2178; see 36 C.F.R. § 251.23 (1982) (regulatory definition); Forest Service
Manual § 4063 (providing further guidance); see also 36 C.F.R. § 219.25 (1982)
(requiring the Forest Service to identify RNAs during the process of creating or
amending a forest plan); 36 C.F.R. § 251.23 (1982) (requiring the Forest Service to
preserve RNAs in “virgin or unmodified condition”).



                                            - 12 -
Botanical Areas.17 See id. at 2466-67, 2512-16.

       The Chief said the Forest Service needed to re-evaluate whether “adequate

measures are in place” to protect such species and areas from the deleterious effects of

livestock grazing. Id. at 2466. He noted, however, “[w]here existing measures are

determined to be adequate, no further actions are required relative to ongoing grazing

activities.” Id.

       For sensitive plants, the Chief said the 1997 Forest Plan did not adequately

evaluate the viability of sensitive plant species, properly disclose the indirect and

cumulative effects of livestock on sensitive plants, or create adequate methods to mitigate

sensitive plant damage from forest management activities such as livestock grazing,

noxious weed control, and sedimentation prevention. Id. at 2512-2516.

               ii. NEPA Shortcoming

       The Chief found the 1997 Forest Plan did not comply with NEPA’s requirement to

take a “hard look” because it made assumptions about ecological impacts and did not




       17
          Botanical Areas are places of scientific interest that “exhibit plant communities,
associations, and/or individual species of particular interest” and may provide protection
for “sensitive species.” 2005 Revised Forest Plan, App. at 2183; see also Forest Service
Manual § 2372.05(3) (defining “Botanical Area” as “a unit of land that contains plant
specimens, plant groups, or plant communities that are significant because of their form,
color, occurrence, habitat, location, life history, arrangement, ecology, rarity, or other
features”). The Forest Service typically designates an area of interest as a Botanical Area
until a full RNA assessment can be conducted. 1997 Record of Decision, App. at 325-26.

properly collect measurements, such as species monitoring and grazing impacts.18 Id. at

2508-10, 2537.

       c. Re-evaluation of the 1997 Forest Plan and the Chief’s interim management
          instructions

       The Chief affirmed the 1997 Forest Plan only in part and issued instructions to re-

evaluate and remedy the deficiencies he identified. Id. at 2462, 2521.

       The Chief’s interim management instructions for the re-evaluation of the 1997

Forest Plan directed the Forest Service to: (1) designate new acreage and protections for

northern goshawk habitat, id. at 2464-65, 2523-24; (2) create a minimum density of snags

in various areas of the BHNF, id. at 2465-66, 2525-26; (3) conduct further analysis and

data collection on all MIS in the BHNF, id. at 2466, 2527; (4) further survey Sensitive

Species’ populations and habitats, id. at 2464, 2522-23; and (5) create and implement

measures to protect sensitive plants and animals in areas where there was ongoing

livestock grazing, id. at 2528.19




       18
        The Chief, however, found the 1997 Forest Plan complied with other aspects of
NEPA, such as the “range of reasonable alternatives” requirement. See Chief’s 1999
Decision, App. at 2541-48.
       19
         This included instructions to establish “[s]pecific conservation measures” that
“minimize[] risks to sensitive species viability,” “monitor one or more measures of
stream habitat integrity,” create additional protections for “sensitive plants in designated
Botanical Areas,” and “[e]nsure that all known colonies of sensitive snail species . . . are
protected from adverse effects of livestock use and other management activities.” Id. at
2528.

2. Settlement Agreement

       When the Chief issued his 1999 Decision, the Forest Service had already spent

two years implementing the 1997 Forest Plan in various site-specific projects, some of

which Biodiversity administratively challenged—such as a timber sale project in the

Beaver Park area of the BHNF. After the Forest Service denied Biodiversity’s Beaver

Park administrative challenge, Biodiversity challenged the project’s validity in the

Colorado federal district court. Biodiversity argued the Forest Service could not allow

the Beaver Park timber sale to proceed because the sale had been authorized under the

flawed 1997 Forest Plan.

       In 2000, Biodiversity and the Forest Service agreed to settle the Beaver Park

timber sale litigation. The district court included the settlement agreement (the

“Settlement Agreement”) in its dismissal order. Settlement Agreement, App. at 415, 444-

47. The Settlement Agreement required the Forest Service to remedy the deficiencies in

the 1997 Forest Plan in two phases.

       During Phase I, the Forest Service would amend the 1997 Forest Plan to

incorporate the Chief’s interim management instructions, pending more thorough analysis

and re-evaluation of the Plan. Id. at 435-36.

       During Phase II, the Forest Service would engage in a public notice and comment-

making process to amend the 1997 Forest Plan “to ensure compliance with requirements

of NFMA, its implementing regulations and agency policy, and all inadequacies

identified in the Chief’s [1999 Decision] . . . . Phase II shall address all of the issues

identified in . . . this settlement agreement, including northern goshawk, Management


                                              - 15 -
Indicator Species, and Research Natural Areas.” Id. at 436. The Phase II Amendment

would replace the Phase I Amendment.

       The Colorado federal district court retained jurisdiction to enforce the Settlement

Agreement. Id. at 442. The Settlement Agreement stated it “shall expire . . . upon

promulgation of the Phase II forest plan amendment, and upon the completion of any

additional analysis required by this agreement . . . .” Id. at 443.

3. Implementation of the Chief’s 1999 Decision and 2000 Settlement Agreement

       a. Phase I Amendment

       The Forest Service promulgated the Phase I Amendment in May 2001. It

incorporated the interim management instructions identified in the Chief’s 1999 Decision

and added protections for snags and Sensitive Species. Phase I Amendment Decision

Notice and FONSI, App. at 346-48. Biodiversity does not challenge the Phase I

Amendment.

       b. Phase II Amendment

       During the next four years—2001 to 2005—the Forest Service conducted a more

thorough analysis of the BHNF to prepare the Phase II Amendment. Also, between 2000

and 2005, several large forest fires burned over 150,000 acres of the BHNF, and between

1997 and 2005, a mountain pine beetle infestation spread from 5,200 to over 100,000

affected acres. 2005 Record of Decision, App. at 1122. As a result, the scope of “the

Phase II Amendment was expanded from the original purpose of species viability and

RNAs to include fire and insect issues.” Id. at 1122.




                                             - 16 -
       The Forest Service summarized its Phase II analysis in a Final EIS under NEPA.

Id. at 1132. The scope of the Phase II Amendment was to: (1) “[c]ompl[y] with the

Chief’s October 1999 [Administrative] Appeal Decision” and correct various deficiencies

in the 1997 Forest Plan by ensuring the viability of species, following MIS requirements,

and creating monitoring objectives for Sensitive Species; (2) “fulfill[] components of the

2000 Settlement Agreement to complete an analysis of candidate RNAs . . . and evaluate

the viability of MIS and northern goshawk”; and (3) “modify[] management direction for

fire hazard and insect risk to address both species viability and diversity and effects on

resources, human safety, and property . . . .’” Id. at 1156.

       The Forest Service considered six alternatives to meet those purposes: (1) re-

implement the 1997 Forest Plan, id. at 1133; (2) take “no action” and simply “continue to

implement the direction included in the Phase I Amendment,” id.; (3) provide for

diversity by emphasizing ideal habitat, id.; (4) focus on creating a dense, mature forest

id.; (5) allow timber harvest to equal annual timber growth, id. at 1134;20 or

(6) emphasize “fire and insect hazard reduction,” target “conditions and conservation

strategies for species viability,” and establish objectives for ideal habitat (similar to

Alternative 3), id. See also id. at 1201-06.




       20
         Alternative 5 was dropped from consideration because it “required broad-scale
change in management areas beyond the scope” of the Phase II Amendment and “would
have extended the decision to a complete revision of the 1997 [Forest] Plan.” 2005
Record of Decision, App. at 1134.



                                               - 17 -
       The Forest Service examined the pros and cons of each alternative, analyzing how

each would affect the various forest ecosystems, id. at 1208-1281; the Emphasis Species,

Threatened and Endangered Species, Sensitive Species, and MIS, id. at 1282-1504;

Botanical Areas and RNAs, id. at 1520-40; fire hazards and the insect infestations, id. at

1541-75; and livestock grazing, id. at 1591-96.

       The Forest Service ultimately chose Alternative 6—which became the Phase II

Amendment—as the “environmentally preferred alternative.” Id. at 1136; see also id. at

1122. The Forest Service noted that Alternative 6 would “reduce the incidence of high

intensity wildfires and . . . reduce the likelihood that endemic insect populations will

grow to epidemic levels.” Id. at 1123. This alternative would not eliminate the risks of

fire and insect infestation, but it would “minimize negative watershed and wildlife

impacts and . . . reduce fire suppression costs.” Id.

       The Forest Service acknowledged Alternative 6 would adversely affect some

forest species and explained that “[w]e cannot separate species viability from the effects

of fire and insects in the” forest plan. Id. The Forest Service was willing to “accept[]

small short-term negative effects on fish, wildlife, and plant populations caused by

vegetation treatments that reduce forest density” because it believed “these treatments

protect and provide habitat needed for long-term viability by reducing susceptibility to

damaging fires and insect epidemics.” Id. at 1128.

       In October 2005, the Forest Service adopted and issued Alternative 6 as the Phase

II Amendment, consisting of a 2005 Record of Decision, a 2005 Final EIS, and a 2005

Revised Forest Plan.

4. Biodiversity’s Challenges to the Phase II Amendment

      a. Administrative challenges

      In 2006, Biodiversity challenged the Phase II Amendment, arguing it fails to

comply with NFMA, the 1982 Rule, NEPA, the Chief’s 1999 Decision, and the

Settlement Agreement.21 In November 2006, the Chief upheld the Phase II Amendment

(“Chief’s 2006 Decision”). Chief’s 2006 Decision, App. at 2698.

      In separate administrative cases, Biodiversity also challenged nine site-specific

projects that the Forest Service had implemented under the Phase II Amendment.22

Biodiversity argued the projects violate NFMA, the 1982 Rule, NEPA, the Chief’s 1999

Decision, and the Settlement Agreement. The Chief denied all nine challenges, including

         See Western Watershed’s Notice of Administrative Appeal, App. at 2581;
Prairie Hills Audubon Society’s Notice of Administrative Appeal, App. at 2600;
Biodiversity Conservation Alliance et al.’s Notice of Administrative Appeal, App. at
2612.
      22
          In this appeal, Biodiversity only briefly mentions these nine site-specific
projects. Its arguments mainly urge the invalidity of the Phase II Amendment.
Biodiversity appears to contend that if the Phase II Amendment is invalid, any site-
specific projects implemented under it must also be invalid. See Notice of Appeal of
Dean Timber Sale, App. at 3751; Notice of Appeal of Moskee Timber Sale, App. at 4174,

Decision, App. at 3883, 3886. In January 2011, the Chief denied the last site-specific

challenge to the Mystic Range Project.24 Mystic Allotment Decision, App. at 4629-30.

      b. Wyoming litigation

      In October 2011, Biodiversity petitioned for review of agency action in the

Wyoming federal district court under the Administrative Procedure Act, 5 U.S.C.

§ 706(2)(A) & (D). Pet. for Review, App. at 25, 31. Biodiversity argued the Forest

Service’s actions promulgating the Phase II Amendment and implementing the

accompanying nine site-specific projects were arbitrary, capricious, an abuse of

discretion, and otherwise not in accordance with NFMA, the 1982 Rule, NEPA, the

Chief’s 1999 Decision, and the 2000 Settlement Agreement. Biodiversity’s petition

      23
          The Dean Project authorized timber harvest in the Redwater Creek watershed
area in the Bearlodge District of the BHNF. The project’s stated purpose was to “reduce
the risk of uncharacteristically intense wildfire behavior and mountain pine beetle
infestation and to improve terrestrial and aquatic habitats.” Dean Timber Sale Decision,
App. at 3886. Biodiversity alleged the Dean Project fell “incredibly short” of protecting
“imperiled wildlife, fish, and plants” because it was implemented under the allegedly
flawed Phase II Amendment. Notice of Appeal of Dean Timber Sale, App. at 3751.
        The Chief denied the administrative appeal, reasoning that nothing in the appeal
caused him to believe the Dean Project violated any “law, regulation, or policy.” Dean
Timber Sale Decision, App. at 3884.
      24
          The Mystic Range Project authorized continued grazing in the Norbeck Wildlife
Preserve for three to five years. Mystic Allotment Decision, App. at 4642. Biodiversity
alleged the Forest Service had failed to comply with all of NEPA’s procedural
requirements before authorizing the grazing. Biodiversity also argued the grazing
adversely affected sensitive plants in violation of NFMA. Notice of Appeal of Mystic
Allotments, App. at 4606.
       The Chief denied the administrative appeal, reasoning that he found “no violation
of law, regulation, or policy.” Mystic Allotment Decision, App. at 4643.

against them. See Pet. for Review, App. at 26-27, 30-31.

         In November 2012, the district court upheld the Forest Service’s actions. It denied

a motion for reconsideration in April 2013. Biodiversity timely appealed (Case No. 13-

8053).

         c. Colorado litigation

         In the meantime, the Beaver Park litigation that Biodiversity filed in 1999 in the

Colorado federal district court lay dormant. After its defeat in Wyoming, Biodiversity

attempted in May 2013 to reopen the Colorado case by moving to enforce the Settlement

Agreement and compel the Forest Service to prepare a Phase II Amendment that would

comply with NFMA, the 1982 Rule, the Chief’s 1999 Decision, and the Settlement

Agreement.

         Relying on laches, the district court denied the motion, reasoning that Biodiversity

had waited too long to enforce its rights under the Settlement Agreement. Biodiversity

timely appealed (Case No. 13-1352).

         d. Appeals consolidated

         Biodiversity moved to consolidate the two appeals. The Forest Service did not

object. We granted the motion because the cases “involve a common nucleus of facts and

similarity of legal issues . . . .” Order at 2, Biodiversity v. USFS, Nos. 13-1352 & 13-

8053, (10th Cir. Sep. 3, 2013), ECF No. 10104703.

                      II. DISCUSSION—WYOMING APPEAL

       Because NFMA and NEPA do not provide a private right of action, we review

Biodiversity’s challenges to the Phase II Amendment and the nine site-specific projects

as final agency actions under the Administrative Procedure Act (“APA”). Utah Envtl.

Cong. v. Bosworth, 443 F.3d 732, 739 (10th Cir. 2006).25

       We first address Biodiversity’s standing and our standard of review. We then

address Biodiversity’s arguments challenging the Forest Service’s actions under NFMA

and NEPA.




       25
          Biodiversity brings its APA challenges under NFMA, NEPA, and their
implementing regulations. Pet. for Review, App. at 30-31. It also claims the Forest
Service’s Phase II Amendment does not comply with the Chief’s 1999 Decision and the
Settlement Agreement. Id. at 31.
        The APA provides the framework for judicial review of agency action. See 5
U.S.C. § 702 (enabling a person “adversely affected or aggrieved by agency action within
the meaning of a relevant statute” to obtain judicial review). The court may grant relief
only when a petitioner shows its claims “fall within the zone of interests protected by the
statute forming the basis of [its] claims.” State of Utah v. Babbitt, 137 F.3d 1193, 1203
(10th Cir. 1998) (quotations omitted); see also City of Albuquerque v. U.S. Dep’t of
Interior, 379 F.3d 901, 915 (10th Cir. 2004) (noting that statutes, regulations, and certain
executive orders may be a basis for an APA claim); Am. Fed. of Gov’t Emps., AFL-CIO
v. Rumsfeld, 321 F.3d 139, 144-45 (D.C. Cir. 2003) (concluding petitioners could not
bring a challenge based on certain agency instructions, directions, and regulations
because they did not fall within the meaning of a relevant statute).
        Biodiversity has not shown that either the Chief’s 1999 Decision or the Settlement
Agreement are a “relevant statute” or otherwise fall within the “zone of interests
protected by the statute[s] forming the basis” of its claims. It therefore cannot rely on
them as a legal basis to establish an APA violation. We will, however, consider the
Chief’s 1999 Decision and the Settlement Agreement as factors in our APA analysis.

                                       A. Standing

       We agree with the district court that the uncontested declarations submitted by

individual members of each of the Biodiversity plaintiffs26 were sufficient to establish

Article III standing. They stated aesthetic and recreational injuries caused by the Forest

Service’s Phase II Amendment and redressable through this lawsuit. See Friends of the

Earth, Inc. v. Laidlaw Envtl. Servs. (TOC), Inc., 528 U.S. 167, 180 (2000) (“[T]o satisfy

Article III’s standing requirements, a plaintiff must show (1) it has suffered an ‘injury in

fact’ that is (a) concrete and particularized and (b) actual or imminent, not conjectural or

hypothetical; (2) the injury is fairly traceable to the challenged action of the defendant;

and (3) it is likely, as opposed to merely speculative, that the injury will be redressed by a

favorable decision.”) (citing Lujan v. Defenders of Wildlife, 504 U.S. 555, 560-61

(1992)).

                                 B. Standard of Review

       The standard of review for Biodiversity’s NFMA and NEPA claims is the same

because we consider them both under the APA. We review de novo a district court’s

decision in an APA case. Utah Envtl. Cong. v. Bosworth, 443 F.3d at 739.

       Under the APA, any “person suffering legal wrong because of agency action, or

adversely affected or aggrieved by agency action within the meaning of a relevant statute,


       26
         The Appellants each filed declarations from one or more of their members in
support of standing. See Decl. of Mr. Brademeyer, App. at 36; Decl. of Mr. Clauson,
App. at 44; Decl. of Ms. Hilding, App. at 50; Decl. of Mr. Kessler, App. at 59; Decl. of
Mr. Molvar, App. at 64; Decl. of Mr. Ratner, App. at 69.

is entitled to judicial review thereof.” 5 U.S.C. § 702. The reviewing court shall set

aside the agency action under § 706(2) if it is:

       (A) arbitrary, capricious, an abuse of discretion, or otherwise not in
       accordance with law; (B) contrary to constitutional right, power, privilege,
       or immunity; (C) in excess of statutory jurisdiction, authority, or
       limitations, or short of statutory right; (D) without observance of procedure
       required by law; (E) unsupported by substantial evidence . . . ; or
       (F) unwarranted by the facts to the extent [they] are subject to trial de novo
       by the reviewing court.

Id. § 706(2); see also Citizens to Preserve Overton Park, Inc. v. Volpe, 401 U.S. 402, 414

(1971).

       In this appeal, Biodiversity relies on § 706(2)(A), arguing the agency’s action was

arbitrary and capricious.27 See Aplt. Br. at 19. Under § 706(2)(A), an agency’s action is

“arbitrary and capricious ‘if the agency . . . entirely failed to consider an important aspect

       27
          Section 706(2)(A)’s “arbitrary or capricious” standard “is the ‘default’ standard
in the federal system and applies whenever the statute does not compel some other
standard.” Charles H. Koch, Jr. & Richard Murphy, 3 Admin. L. & Prac. § 9:25[1] (3d
ed.); see also Hydro Res., Inc. v. E.P.A., 608 F.3d 1131, 1145 (10th Cir. 2010) (stating
that when the relevant statute does not mandate a particular standard of review, the APA
“provides the default” under § 706(2)(A)); Olenhouse v. Commodity Credit Corp., 42
F.3d 1560, 1575 n.25 (10th Cir. 1994) (“The ‘arbitrary or capricious’ standard of
§ 706(2)(A) is . . . a catch-all, picking up administrative misconduct not covered by the
more specific paragraphs.”).
        In the district court, Biodiversity brought its claims under “§ 706(2)(A) and (D).”
Pet. for Review, App. at 31. The district court used only the “arbitrary and capricious”
standard under § 706(2)(A). See, e.g., Order Upholding Agency Action, App. at 92.
Biodiversity did not challenge this aspect of the district court’s order. See generally
Biodiversity’s Mot. for Reconsideration, Biodiversity v. USFS, No. 1:11-cv-00340-SWS
(D. Wyo. Dec. 7, 2012), ECF No. 84; Reply in Supp. of Mot. for Reconsideration,
Biodiversity v. USFS, No. 1:11-cv-00340-SWS (D. Wyo. Jan. 16, 2013), ECF No. 90.
On appeal, Biodiversity cites § 706(2)(A) and discusses the arbitrary and capricious
standard, see, e.g., Aplt. Br. at 19, but does not cite § 706(2)(D) or discuss its failure to
observe procedure. As a result, we limit our APA review to § 706(2)(A).

of the problem, offered an explanation for its decision that runs counter to the evidence

before the agency, or is so implausible that it could not be ascribed to a difference in view

or the product of agency expertise.’” Utah Envtl. Cong. v. Bosworth, 443 F.3d at 739

(quoting Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co., 463 U.S. 29, 43

(1983)). Likewise, an agency’s decision is arbitrary and capricious if the agency failed to

base its decision on “consideration of the relevant factors,” or if “there has been a clear

error of judgment” on the agency’s part. Id.

       “When courts consider such challenges, an agency’s decision is entitled to a

presumption of regularity, and the challenger bears the burden of persuasion.” San Juan

Citizens Alliance v. Stiles, 654 F.3d 1038, 1045 (10th Cir. 2011) (citations omitted). Our

deferential review “is especially strong where the challenged decisions involve technical

or scientific matters within the agency’s area of expertise.” Utah Envtl. Cong. v. Russell,

518 F.3d 817, 824 (10th Cir. 2008) (citing Marsh v. Or. Natural Res. Council, 490 U.S.

360, 378 (1989)); see also San Juan Citizens, 654 F.3d at 1045 (“[W]hen specialists

express conflicting views, an agency must have discretion to rely on the reasonable

opinion of its own qualified experts, even if, as an original matter, a court might find

contrary views more persuasive.” (quotations omitted)).

       Sometimes, as here, a plaintiff will also challenge the agency’s interpretation of

the applicable regulations. We must determine which interpretation to judge the agency’s

action against. In making this determination, we give “substantial deference” to the

agency’s interpretation of its own regulations. Utah Envtl. Cong. v. Troyer, 479 F.3d

1269, 1281 (10th Cir. 2007) (“We may reject the agency’s interpretation only when it is


                                             - 25 -
unreasonable, plainly erroneous, or inconsistent with the regulation’s plain meaning.”

(quotations omitted)).

       Although deferential, our inquiry must “be searching and careful.” Ecology Ctr.,

Inc. v. USFS, 451 F.3d 1183, 1188 (10th Cir. 2006) (quotations omitted). We will not,

for example, accept appellate counsel’s post-hoc rationalizations for agency action—we

must uphold the agency’s action “if at all, on the basis articulated by the agency itself.”

Colo. Wild, Heartwood v. USFS, 435 F.3d 1204, 1213 (10th Cir. 2006) (quoting Motor

Vehicle Mfrs., 463 U.S. at 50).

                                    C. NFMA Issues

       To address Biodiversity’s claim that the Phase II Amendment violates NFMA, we

first determine (1) which regulations apply to the Phase II Amendment. We then analyze

(2) whether the Phase II Amendment fails to: (a) comply with the viability mandate of

the 1982 Rule; (b) adequately protect RNAs and Botanical Areas; or (c) conduct a proper

suitability and capability analysis for MIS and livestock grazing.

1. Regulations Applicable to the Phase II Amendment

       NFMA regulations govern preparation of forest plans. 16 U.S.C. § 1604(a) & (g);

Silverton Snowmobile Club v. USFS, 433 F.3d 772, 785 (10th Cir. 2006). Forest plans

and their amendments typically must comply with the regulation in place at the time the

plan or amendment is final. Ecology Ctr., 451 F.3d at 1191. Because the Forest Service

issued the Phase II Amendment after the 2005 Rule was in place, it would normally need

to comply with that rule. But a transition provision in the 2005 Rule allowed the Forest

Service to amend the 1997 Forest Plan based on the superseded 1982 Rule. See 36


                                             - 26 -
C.F.R. § 219.14(b) & (e) (2005); see also Forest Guardians v. USFS, 495 F.3d 1162,

1168 (10th Cir. 2007) (“Forest plans may require particular standards to be followed

regardless of later changes in the regulations.” (quotations omitted)).

       The Phase II Amendment repeatedly states it is based on the 1982 Rule and the

2005 Modification codified in § 219.14(f). See, e.g., 2005 Record of Decision, App. at

1141 (“The Phase II Amendment is done under the provisions of the former 1982 NFMA

planning rule as modified by 36 CFR 219.14 (f).”); see also id. at 1122 (same); 2005

Final EIS, App. at 1150, 1441 (same); 2005 Revised Forest Plan, App. at 2039, 2102

(same). The Forest Chief recognized this in his 2006 decision denying Biodiversity’s

challenge to the Phase II Amendment. See Chief’s 2006 Decision, App. at 2698-99 &

n.1. So does Biodiversity. Aplt. Br. at 29; 33, 35; Aplt. Reply Br. at 1-5.

       Although the Forest Service describes the rules applicable to the Phase II

Amendment differently in its brief, see Aplee. Br. at 22-24, 29, we do not see how the

agency can vary from what is clearly stated in the Phase II Amendment itself. We

therefore evaluate the Phase II Amendment using the 1982 Rule as modified by the 2005

Modification. The parties debate how these rules should be interpreted and applied, in

particular what the regulations require the Forest Service to do to ensure species viability.

2. Biodiversity’s NFMA Challenges to the Phase II Amendment

       a. Species viability mandate

       Biodiversity argues the Phase II Amendment fails to comply with the 1982 Rule’s

“viability mandate” in § 219.19.




                                             - 27 -
       The 1982 Rule required the Forest Service to “maintain viable populations” of

plants and animals in the BHNF. 36 C.F.R § 219.19 (1982). Section 219.19 provided, in

relevant part: “to insure that viable populations will be maintained, habitat must be

provided to support, at least, a minimum number of reproductive individuals and that

habitat must be well distributed so that those individuals can interact with others in the

planning area.” 36 C.F.R. § 219.19 (1982). Section 219.19 also specifically required the

Forest Service to collect population data on MIS. See id. § 219.19(a), (a)(1), (a)(2), and

(a)(6). We have recognized § 219.19 used MIS to “measure the impact of habitat

changes on the Forest’s diversity.” Utah Envtl. Cong. v. Bosworth, 372 F.3d 1219, 1226

(10th Cir. 2004) (quotations omitted). MIS therefore served under § 219.19 as “a

bellwether for other species . . . .” Forest Guardians v. USFS, 641 F.3d 423, 427 (10th

Cir. 2011) (per curiam) (quotations omitted). Section 219.14(f) of the 2005 Rule—the

2005 Modification—allowed the Forest Service to “comply with any obligations relating

to [MIS] by considering data and analysis relating to habitat . . . .” 36 C.F.R. § 219.14(f)

(2005).

       Biodiversity claims the Forest Service violated § 219.19’s “viability mandate” in

failing to: (i) conduct adequate viability analyses to ensure the viability of species; and

(ii) provide sufficient habitat and protections in the Phase II Amendment to ensure the

viability of northern goshawk, snag-dependent species, and sensitive plants.

              i. Viable species mandate under the applicable regulations

       Biodiversity claims the Phase II Amendment fails to comply with § 219.19’s

viability mandate and the 2005 Modification because the Forest Service did not collect or


                                             - 28 -
consider enough population data or create adequate population objectives to ensure the

viability of species. As stated above, under the APA, Biodiversity must show the Forest

Service acted arbitrarily and capriciously under the applicable regulations.

                     1) Interpretation of regulations

       Biodiversity and the Forest Service disagree about how to interpret the applicable

regulations regarding species viability. We must assess this interpretation issue before

we proceed to consider the merits of Biodiversity’s APA challenge.

       Using familiar rules of construction, see Jicarilla Apache Tribe v. Andrus, 687

F.2d 1324, 1332 (10th Cir. 1982) (“Regulations are generally subject to the same rules of

construction as statutes.”), we first “determine whether the language at issue has a plain

and unambiguous meaning with regard to the particular dispute in the case,” Robinson v.

Shell Oil Co., 519 U.S. 337, 340 (1997). If the meaning is plain, it controls. Id. If the

meaning is ambiguous, we defer “to an agency’s interpretation of its own ambiguous

regulation, even when that interpretation is advanced in a legal brief,” Christopher v.

SmithKline Beecham Corp., 132 S. Ct. 2156, 2166 (2012) (citing Auer v. Robbins, 519

U.S. 452 (1997)), unless the agency’s interpretation is “plainly erroneous or inconsistent

with the regulation,” id. (quotations omitted); see also Utah Envtl. Cong. v. Troyer, 479

F.3d 1269, 1281 (10th Cir. 2007) (stating we reject Auer deference when the agency’s

interpretation is “unreasonable”). In other words, we “accord Auer deference to the

[agency’s] interpretation” when we determine it “is a reasonable interpretation of its own

regulation.” Decker v. Nw. Envtl. Def. Ctr., 133 S. Ct. 1326, 1331, 1337 (2013). “[A]n




                                            - 29 -
agency’s interpretation need not be the only possible reading of a regulation—or even the

best one—to prevail.” Id. at 1337.

       Biodiversity contends § 219.19’s “plain language” defines viable species in terms

of “minimum number of individuals.” Aplt. Br. at 30-31 (emphasis in original). But

beyond that, Biodiversity fails to explain whether its interpretation of the species viability

mandate to collect or consider population data or create population objectives is based on

the plain meaning of § 219.19 or a reasonable reading of the regulation’s ambiguous

terms, nor does Biodiversity address whether § 219.14(f) has a plain meaning. The

Forest Service likewise does not clearly specify whether its interpretation is based on the

regulations’ plain meaning. If we find the regulations’ language is not plain and the

Forest Service’s interpretation of the ambiguous regulations is reasonable, we must defer

to that interpretation.

       To determine which interpretation of the regulations applies to Biodiversity’s APA

challenge, we a) address whether the plain meaning of the regulations requires the Forest

Service to collect or consider population data or create population objectives to comply

with the viability mandate. We conclude the regulations are ambiguous on this score.

We then b) examine whether the Forest Service’s interpretation is reasonable. We

conclude that it is and therefore entitled to Auer deference. Biodiversity’s interpretation

does not convince us otherwise.




                                             - 30 -
                              a) Whether the regulations have a plain meaning or are
                                 ambiguous

       The parties have framed the issue as whether § 219.19 of the 1982 Rule and

§ 219.14(f) of the 2005 Rule imposed a duty on the Forest Service to collect or consider

population data or create population objectives to ensure the viability of species. We

must determine (1) whether § 219.19’s viability mandate plainly states that population

data must be collected or considered or that population objectives must be created, and

for which species, and (2) whether § 219.14(f) unambiguously states how it affects the

MIS obligations created by § 219.19.

       First, as to § 219.19, we find it does not clearly state whether and to what extent

the viability mandate requires more than providing and managing habitat to ensure

species viability. It states, in relevant part:

               Fish and wildlife habitat shall be managed to maintain viable
       populations of existing native and desired non-native vertebrate species in
       the planning area. For planning purposes, a viable population shall be
       regarded as one which has the estimated numbers and distribution of
       reproductive individuals to insure its continued existence is well distributed
       in the planning area. In order to insure that viable populations will be
       maintained, habitat must be provided to support, at least, a minimum
       number of reproductive individuals and that habitat must be well distributed
       so that those individuals can interact with others in the planning area.

36 C.F.R. § 219.19 (1982).

       The 1982 Rule mandates that “habitat shall be managed to maintain viable

populations of existing native and desired” plants and animals. Id. It defines “viable

population” as “one which has the estimated numbers and distribution of reproductive

individuals to insure its continued existence is well distributed in the planning area.” Id.



                                                  - 31 -
And it requires “habitat must be provided to support, at least, a minimum number of

reproductive individuals and that habitat must be well distributed” to ensure a viable

population. Id.28

       Although § 219.19 states the Forest Service must provide and manage habitat to

ensure viable species, the text does not clearly state whether and to what extent collecting

or considering population data was necessary. The regulation speaks of the habitat

responsibility using terms such as “estimated numbers,” “distribution of reproductive

individuals,” and “minimum number.” Id. Although that language may reasonably be

read as having imposed a population data requirement, these references do not plainly

direct the Forest Service to collect or consider population data or create population

objectives. For example, § 219.19’s requirement that “habitat shall be managed to

maintain viable populations,” does not prescribe how to achieve “viable populations”—

whether through habitat management, population data, or both. And even if we were to

read § 219.19 to include a population data requirement, the regulation says nothing about

what and how much data must be collected, how such data must be analyzed, and which

species must be included.

       We conclude § 219.19 is ambiguous as to whether and to what extent the Forest

Service must collect and consider population data or create population objectives to

ensure the viability of species.


       28
         The 2005 Modification was directed at MIS and did not affect this general
species mandate.



                                            - 32 -
      Second, the effect of § 219.14(f) of the 2005 Modification also is not plain.

Regarding MIS, § 219.19 of the 1982 Rule states, in relevant part:

              (a) Each alternative shall establish objectives for the maintenance
      and improvement of habitat for management indicator species selected
      under paragraph (g)(1) of this section, to the degree consistent with overall
      multiple use objectives of the alternative. To meet this goal, management
      planning for the fish and wildlife resource shall meet the requirements set
      forth in paragraphs (a)(1) through (a)(7) of this section.

             (a)(1) In order to estimate the effects of each alternative on fish and
      wildlife populations, certain vertebrate and/or invertebrate species present
      in the area shall be identified and selected as management indicator species
      and the reasons for their selection will be stated. These species shall be
      selected because their population changes are believed to indicate the
      effects of management activities. . . .

            (a)(2) Planning alternatives shall be stated and evaluated in terms of
      both amount and quality of habitat and of animal population trends of the
      management indicator species.

                                         [* * *]

            (a)(6) Population trends of the management indicator species will be
      monitored and relationships to habitat changes determined. . . .

36 C.F.R. § 219.19 (1982). Thus, § 219.19 requires the Forest Service to select MIS,

“monitor[]” the MIS “[p]opulation trends,” and “evaluate[]” the population data “to

estimate the effects” of forest management on the other species in the forest. 36 C.F.R.

§ 219.19(a), (a)(1), (a)(2), & (a)(6) (1982). Accordingly, we have held that for MIS,

§ 219.19 of the 1982 Rule requires the Forest Service to “monitor” population data. See

Utah Envtl. Cong. v. Bosworth, 372 F.3d 1219, 1226 (10th Cir. 2004) (“Plainly the

regulations require that the Forest Service monitor population trends of the MIS in order




                                           - 33 -
to evaluate the effects of forest management activities on the MIS and the viability of

desired fish and wildlife populations in the forest more generally.”).

       The 2005 Modification, however, created new options for the Forest Service as to

MIS. It states:

              Management indicator species. For units with plans developed,
       amended, or revised using the provisions of the planning rule in effect prior
       to November 9, 2000 [i.e., the 1982 Rule], the Responsible Official may
       comply with any obligations relating to [MIS] by considering data and
       analysis relating to habitat unless the plan specifically requires population
       monitoring or population surveys for the species. Site-specific monitoring
       or surveying of a proposed project or activity area is not required, but may
       be conducted at the discretion of the Responsible Official.

36 C.F.R. § 219.14(f) (2005); see also 70 Fed. Reg. 1023, 1052 (Jan. 5, 2005)

(promulgating the 2005 Rule and explaining “§ 219.14(f) provides that MIS obligations

may be met by considering data and analysis relating to habitat”).

       The 2005 Modification authorizes the Forest Service to “comply with any

obligations” relating to MIS by “considering data and analysis relating to habitat.” 36

C.F.R. § 219.14(f) (2005). The phrase “any obligations” connotes a broad scope,

including possibly every MIS obligation imposed by § 219.19. But even the word “any”

may not be plain depending on the regulatory context. See Christopher v. SmithKline

Beecham Corp., 132 S. Ct. 2156, 2170 (2012) (“We have recognized that the modifier

‘any’ can mean different things depending upon the setting . . . .” (quotations omitted)).29


       29
         See also Utility Air Regulatory Grp. v. EPA, 134 S. Ct. 2427, 2451 (2014)
(Breyer, J., concurring in part and dissenting in part) (“I agree with the Court that the
word ‘any,’ when used in a statute, does not normally mean ‘any in the universe.’ . . .
The pursuit of [the] underlying purpose may sometimes require us to ‘abandon’ a ‘literal

And as noted above, § 219.19 is ambiguous as to what “obligations” it creates for MIS

beyond monitoring. In the NFMA and 1982 Rule context, “any obligations relating to

[MIS]” could refer only to MIS monitoring obligations contained in § 219.19(a), (a)(1),

(a)(2), & (a)(6), or could include additional obligations arising from the species viability

mandate.

       Section 219.14(f) is not clear as to whether it completely obviates all possible MIS

obligations imposed in § 219.19—including obligations due to the general species

viability mandate—or only MIS monitoring obligations.

                                        *      *       *

       Accordingly, as to whether and what extent § 219.19 required the Forest Service

to collect and consider population data or create population objectives to meet the species

viability mandate, and the extent to which § 219.14(f) supplanted the Forest Service’s

MIS responsibilities in § 219.19, we conclude the regulations do not convey a plain

meaning and therefore are ambiguous.

                             b) Whether the Forest Service’s interpretation is reasonable

       Because the regulations’ meaning is not plain as to a population data requirement,

we defer to the Forest Service’s interpretation if it is reasonable or unless it is plainly

erroneous or inconsistent with the regulation. See Auer, 519 U. S. at 461. We first

ii) consider Biodiversity’s position, concluding that although Biodiversity advances a

competing interpretation, it has not convinced us the Forest Service’s interpretation

should not be entitled to Auer deference. We accordingly iii) defer to the Forest

Service’s interpretation of the regulations concerning a population data requirement.

                                    i) The Forest Service’s interpretation

       The Forest Service’s interpretation of § 219.19’s viability mandate and the 2005

Modification distinguishes MIS and non-MIS.

       Regarding MIS, the Forest Service acknowledges that before the 2005 Rule,

§ 219.19 of the 1982 Rule required it to “monitor the population trends” of MIS. Aplee.

Br. at 24 (quotations omitted). But the Forest Service contends that § 219.14(f) of the

2005 Rule—the 2005 Modification—made compliance “‘with any obligations relating to

management indicator species’” in the 1982 Rule optional so long as it “‘consider[ed]

data and analysis relating to habitat . . . .’” Aplee. Br. at 23 (quoting 36 C.F.R.

§ 219.14(f) (2005)). The Forest Service contends its reliance on the 2005 Modification

obviates “any” requirement in the 1982 Rule to use MIS population data to ensure species

viability in the Phase II Amendment. See id. at 25.

       Regarding non-MIS, the Forest Service indicates in its brief that the 2005

Modification relieved it of whatever population data gathering obligations arose under

the 1982 Rule. See Aplee. Br. at 29 (“Because the Forest Service properly relied on the

2005 [R]ule in developing the Phase II [Amendment], Biodiversity’s argument

concerning the need for population data under the 1982 Rule fails.”). The Forest Service

clarified its position at oral argument:


                                             - 36 -
       It’s one thing to look at application of the ’82 Rules as interpreted by this
       court with reference to monitoring to MIS and to talk about population data
       because they are selected species. But more broadly, as the district court
       noted there is no decision by this court or any other court that says for non-
       MIS species you’ve got to maintain population data. . . . The Forest
       Service has never believed it had that obligation [to collect non-MIS
       data]. . . . That obligation doesn’t exist.

Oral Arg. at 15:29-15:53, 16:27-16:30, 16:47-16:50. In response to the court’s question,

“beyond MIS, is the Forest Service obligated to count any species?,” id. at 18:28-18:34,

counsel for the Forest Service replied, “I would say there is no general obligation to do

so,” id. at 18:37-18:45.

       The Forest Chief took this position in his 2006 Decision denying Biodiversity’s

administrative appeal. See Chief’s 2006 Decision, App. at 2708-10 (rejecting

Biodiversity’s argument that the 1982 Rule obligated the Forest Service to collect and

consider population data, or estimate the minimum number of individuals to maintain a

viable population, in part, because “[t]here is no policy or regulatory requirement for the

[BH]NF to propose or establish minimum viable population numbers for any of the

species that occur within the planning area”). At least two circuits agree with the Forest

Service regarding the non-MIS. See Sierra Club v. Martin, 168 F.3d 1, 7 (11th Cir. 1999)

(rejecting an argument which interpreted § 219.19 to require collecting data on all species

because it would make nonsensical the regulation’s requirement to collect data on MIS);

Inland Empire Pub. Lands Council v. USFS, 88 F.3d 754, 758, 761-62 & n.8 (9th Cir.

1996) (concluding the Forest Service’ habitat analysis of seven non-MIS Sensitive

Species did not violate § 219.19’s viability mandate).




                                            - 37 -
       In sum, the Forest Service interprets the regulations narrowly to mean that

§ 219.19 of the 1982 Rule obligated the Forest Service to ensure the viability of species

but imposed no duty to use population data other than the MIS monitoring obligations,

and the 2005 Modification relieved the Forest Service of “any” MIS monitoring

obligation.

                                   ii) Biodiversity’s position

       Biodiversity attempts to challenge the Forest Service’s interpretation of the

regulations by positing its own competing interpretation.

       We are bound to defer to the Forest Service’s interpretation, however, unless it is

“unreasonable, plainly erroneous, or inconsistent with the regulation’s plain meaning.”

Troyer, 479 F.3d at 1281 (quotations omitted). Indeed, “[a]n agency’s interpretation need

not be the only possible reading of a regulation—or even the best one—to prevail.”

Decker, 133 S. Ct. at 1337. Accordingly, Biodiversity cannot succeed in challenging the

Forest Service’s interpretation merely by proposing another interpretation, no matter how

reasonable. It must instead convince us that the Forest Service’s interpretation is

unreasonable or plainly erroneous—which Biodiversity does not even attempt to do.

       In any case, Biodiversity has not advanced a persuasive alternative interpretation

to the Forest Service’s. Biodiversity observes the 1982 Rule required the Forest Service

to “ensure viable populations of all native species under § 219.19,” Aplt. Br. at 25, and

“define[d] viability in terms of a minimum number of individuals,” id. at 31 (emphasis in

original). “As such, numerical data is relevant and applicable to viability

determinations . . . .” Id. at 31. Biodiversity further contends the 2005 Modification—


                                            - 38 -
§ 219.14(f)—addressed “MIS monitoring compliance, not viability determinations . . . .”

Aplt. Br. at 33. Biodiversity stresses the difference between MIS monitoring and

maintaining viable species and argues the Forest Service conflates the two. See Aplt.

Reply Br. at 2-3. Although the 2005 Modification “eliminated the 1982 [R]ule’s

requirement to monitor MIS population trends, it did not eliminate the definition of a

viable population,” id. at 6, nor did it “eliminate the relevance, importance and

applicability of population figures and estimates for species viability determinations and

maintenance,” id. at 7.

       Biodiversity therefore generally argues the Forest Service must do more than

habitat analysis to ensure species viability. But beyond that, Biodiversity’s interpretation

of the regulations is difficult to decipher. Biodiversity’s various arguments can be read to

suggest a population data requirement applied to: (1) all species;30 (2) some species

beyond Emphasis Species;31 (3) species “requiring special attention;”32 (4) all Emphasis


       30
           See Aplt. Br. at 25 (“all native species”); Oral Arg. at 7:30-7:39, 7:52-8:01 (“I
also want to emphasize that species viability applies to all native species, not just
management indicator species. . . . By undertaking those viability determinations [in the
Final EIS] beyond management indicator species, the Forest Service recognized that
viability covers all native species.”); but see Oral Arg. at 8:32-8:40 (acknowledging

duties beyond MIS monitoring.37 Compounding this problem is Biodiversity’s failure to

specify what population data must be collected, how it must be analyzed, and whether it

must be collected at all when the Forest Service’s habitat analysis for a particular species

may be adequate to ensure species viability.38 We will not attempt to bring cohesion to

Biodiversity’s interpretation(s). Perry v. Woodward, 199 F.3d 1126, 1141 n.13 (10th Cir.

1999) (declining to address an alternative argument because defendants “have not

                                    iii) Conclusion

       Having reviewed the parties’ interpretations of the regulations, we conclude the

Forest Service’s interpretation is narrow but not unreasonable. It allows the agency

flexibility to use population data, as it has done,39 in meeting the species viability

Aplt. Reply Br. at 6 (“Yet, while Section 219.14(f) of the 2005 rule eliminated the 1982
rule’s requirement to monitor MIS population trends, it did not eliminate the definition of

as insufficiently gathering or analyzing population data).
       38
         The Forest Service conducted habitat analyses for many non-MIS species,
including the eight non-MIS identified by Biodiversity. See 2005 Final EIS, App. at

not persuaded us otherwise, presenting its interpretation in various permutations, leaving

us to guess what it is and without any basis to conclude the Forest Service’s interpretation

is plainly erroneous, inconsistent with the regulations, or otherwise unreasonable.

       For the foregoing reasons, we must defer in these circumstances to the Forest

Service’s interpretation of § 219.19 of the 1982 Rule and § 219.14(f) of the 2005 Rule

        And as to non-MIS, the Forest Service included population data in its analyses for
the Lewis’s woodpecker, northern goshawk, and American marten—either explicitly or
incorporating it by reference. See 2005 Final EIS, App. at 1928-29 (stating three Lewis’s

viability mandate and the 2005 Modification in violation of the APA. Biodiversity fails

to do so.

       Biodiversity contends the Phase II Amendment fails to ensure “species viability as

required by § 219.19.” Aplt Br. at 30. Referring to nine MIS and eight non-MIS

Emphasis Species as examples, it argues the Forest Service did not properly use

population data for those species. Aplt Br. at 30-35; Aplt. Reply Br. at 11-17.40

       As to non-MIS, § 219.19 imposed no obligation to use population data under the

Forest Service’s interpretation.

       As to MIS, the Forest Service conducted habitat viability analyses.41 Biodiversity

faults the Forest Service for failing to use population data for MIS. But under the Forest


       40
          Biodiversity identified nine MIS: black-backed woodpecker, brown creeper,
golden-crowned kinglet, grasshopper sparrow, ruffed grouse, song sparrow, beaver,
white-tailed deer, and mountain sucker. Aplt. Br. at 32-34; Aplt. Reply Br. at 8, 15; see
also 2005 Revised Forest Plan, App. at 2102 (listing MIS).
        Biodiversity also identified eight non-MIS Emphasis Species: northern leopard
frog, redbelly snake, Lewis’s woodpecker, northern goshawk, American marten, fringed
myotis, pygmy nuthatch, and northern flying squirrel. Aplt. Br. at 31; see also 2005 Final
EIS, App. at 1359-60 (listing the first six as “Sensitive Species”); 2005 Final EIS, App. at
1382, 1397, 1403, 1415 (organizing the discussion of the pygmy nuthatch under the
heading “Species of Local Concern—Birds,” and the flying squirrel under “Species of
Local Concern—Mammals”).
        Contrary to Biodiversity’s characterization that the Phase II Amendment
“pointedly avoid[s] the use of population figures to determine species viability,” Aplt.
Reply Br. at 14, the record shows the Forest Service included population data for all nine

Service’s interpretation of the 2005 Modification, the Phase II Amendment may comply

with “any” MIS monitoring obligations imposed under § 219.19 by using habitat data and

analysis in lieu of population data. See 36 C.F.R. § 219.14(f) (2005).

       Biodiversity fails to show how the Phase II Amendment is deficient under the

Forest Service’s interpretation of § 219.19’s viability mandate and the 2005

Modification. We therefore reject its APA claim that the Phase II Amendment violates

the species viability mandate.42

       42
          In its opening brief, Biodiversity mentions in a footnote that a federal district
court held the 2005 Rule unlawful in 2007. Aplt. Br. at 29 n.2 (citing Citizens for Better
Forestry v. USDA, 482 F. Supp. 1059, 1100-01 (N.D. Cal. 2007). The brief refers to the
2005 Rule as “now-invalidated.” Id. at 33. In its reply brief, Biodiversity states,
“[c]ontrary to the Intervenors’ assertion otherwise, [Biodiversity] does not contend in this
appeal that the invalidation of the 2005 rule . . . rendered Phase II unlawful.” Aplt. Reply
Br. at 10.
        This statement indicates Biodiversity does not fault the Forest Service for relying
on § 219.14(f) of the 2005 Rule in preparing the Phase II Amendment. We therefore
understand this statement as Biodiversity’s accepting § 219.14(f) was valid for purposes
of the Phase II Amendment, and our analysis proceeds on that basis.
        We note, however, in the same passage in its reply brief, Biodiversity further
states that “[t]he Forest Service’s response brief correctly notes that in the lower court,
[Biodiversity] argued the invalidation of the 2005 rule further called into question the
lawfulness of the Phase II Amendment.” Aplt. Reply Br. at 10. If Biodiversity actually
wished to make such an argument, it would need to explain why it would be unreasonable
for the Forest Service, in adopting the Phase II Amendment in 2005, to rely on
§ 219.14(f) before any court had held the 2005 rule invalid.
        But Biodiversity then suggests it does not wish to make such an argument:

       Before this Court, however, [Biodiversity] asserts that regardless of
       whether the 2005 rule was in effect at the time the Forest Service adopted
       Phase II, the agency still had an obligation to maintain viable populations
       of species in compliance with the 1982 rule’s provisions it purported to
       follow. Section 219.14(f) of the 2005 rule did not alter that requirement or
       the plain language of the 1982 rule explaining what constitutes a viable

              ii. Viable species mandate—habitat and protections

       Apart from challenging Forest Service’s species viability analyses generally,

Biodiversity also argues the Phase II Amendment violates § 219.19’s viability mandate

by failing to provide adequate: (1) habitat or protection for the northern goshawk;

(2) habitat for snag-dependent species; and (3) protection for sensitive plants.43 These

three challenges contest whether the Phase II Amendment provides adequate habitat or

protections to ensure the species’ viability.

        Our analysis is premised on § 219.14(f) having been in effect when the Forest
Service adopted the Phase II Amendment. If, based on this last quoted statement from its
reply brief, Biodiversity could somehow fall back on the argument that § 219.14(f) was
not in effect in 2005, the Forest Service has explained that a transition rule adopted in
2000 would have been in effect. Aplee. Br at 27-28; see also 36 C.F.R. § 219.35 (2001)
(allowing the Forest Service to “consider the best available science in implementing, and,
if appropriate, amending the current plan”); 36 C.F.R. § 219.35 App. B (2004)
(interpreting the 2000 transition rule); Utah Envtl. Cong. v. Bosworth, 443 F.3d 732, 749
(10th Cir. 2006) (concluding the Forest Service was not required to collect MIS
population data under the 2000 transition provision and its “best available science”
standard).
        The Forest Service interprets the 2000 transition rule as consistent with its
interpretation of § 219.19 of the 1982 Rule together with § 219.14(f) of the 2005 Rule.
See Aplee. Br. at 27-28. We again find the agency’s interpretation reasonable and
entitled to deference under Auer. Biodiversity argues against application of the 2000
transition rule only briefly. It has not developed that argument or shown that the Forest
Service violated the APA through non-compliance with the 2000 transition rule. See
Aplt. Br. at 35 (arguing only briefly); Aplt. Reply Br. at 8-9 (same).
       43
          Biodiversity also claims the Forest Service’s failure to provide habitat or
protections for these three categories violates the Chief’s 1999 Decision and the
Settlement Agreement.
       As noted above, neither document may be an independent basis for an APA
violation. We consider them as factors in determining whether the Forest Service acted
arbitrarily or capriciously when it promulgated the Phase II Amendment.

                     1) Northern goshawk

       Biodiversity contends that, instead of designating specific post-fledging areas for

the northern goshawk,44 the Phase II Amendment lists only general forest-wide goals to

create goshawk-friendly habitat. Aplt. Br. at 35-37, 40. Citing to various scientific

studies, id. at 36 (citing Goshawk Conservation Assessment, App. at 697), Biodiversity

argues the Phase II Amendment fails to provide sufficient dense canopy or large trees for

goshawks.45 Id. at 35-40. Biodiversity further argues the Forest Service failed to impose

restrictions on harvesting large trees in densely canopied areas, making the development

of mature, dense stands of trees “less likely.” Id. at 38.

       The Forest Service acknowledges it shifted from designating specific areas for

goshawks under the Phase I Amendment to using forest-wide goals to create goshawk-

       44
          A “post-fledgling area” is “the area used by the [goshawk] family group from
the time the young fledge until they are no longer dependent on the adults for food.”
Northern Goshawk (Accipiter gentiles atricapillus): A Technical Conservation
Assessment, App. at 697 (citations omitted) (“Goshawk Conservation Assessment”). As
goshawk fledglings mature, they range “farther from the nest over time.” Id. Thus, post-
fledgling areas “may be important to fledglings by providing prey items on which to
develop hunting skills, as well as cover from predators and prey.” Id. A post-fledgling
area is typically smaller than the foraging area used by the goshawk family group. See id.
at 691, 695.
       45
           Relying on various scientific studies—including the extensive Goshawk
Conservation Assessment conducted by the Forest Service—Biodiversity contends
goshawks prefer large trees (at least 16 inches in diameter) with relatively dense canopies
(at least 50% closed) for nesting and post-fledgling areas. Aplt. Br. at 37-38 (arguing
these conditions “might provide the highest quality habitat for goshawks”). Biodiversity
argues the Forest Service did not conduct a proper goshawk viability analysis because it
included areas without the qualities “preferred by goshawks.” See 2005 Final EIS, App.
at 1941-42 (analyzing the goshawk’s viability by examining habitat, including trees as
small as 9 inches in diameter and canopy densities as low as 40% closed).



                                             - 46 -
friendly conditions under the Phase II Amendment. It did so based on new scientific

information about the goshawk. Aplee. Br. at 30-31. During the Phase II Amendment

process, the Forest Service performed a conservation assessment of the northern goshawk

that synthesized information from over 470 goshawk conservation studies, including

some of the same studies cited by Biodiversity. See Goshawk Conservation Assessment,

App. at 635; Aplee. Br. at 32. The Forest Service also reviewed other scientific literature

about goshawks and their habitat, see 2003 Survey Results for Small Forest Owls, the

Northern Goshawk, and Other Raptors of Interest in the Black Hills, South Dakota, App.

at 1049; 2005 Final EIS, App. at 1940-43, and conducted on-site surveys of goshawk

habitats. See 2005 Final EIS, App. at 1940-41. Finally, it performed a biological

evaluation of the goshawk and how the Phase II Amendment might adversely affect the

species. See 2005 Final EIS, App. at 1943-52. The Forest Service concluded a forest-

wide habitat approach would promote goshawk viability. See Aplee. Br. at 31-32.

       Biodiversity’s argument that the Phase II Amendment does not ensure the viability

of the goshawk invites us to compare its scientific analysis with the Forest Service’s. On

that score, “[w]e grant considerable discretion and deference to federal agencies on

matters that require a high level of technical or scientific expertise.” Forest Guardians v.

USFS, 641 F.3d 423, 442 (10th Cir. 2011) (per curiam) (citing Marsh v. Or. Natural Res.

Council, 490 U.S. 360, 377 (1989)). Biodiversity thinks the Forest Service should have

designated post-fledgling areas. The Forest Service decided on a forest-wide habitat

approach. Both rely on science, and “it is not our role to weigh competing scientific

analyses.” Forest Guardians, 641 F.3d at 442 (quotations omitted). Biodiversity has not


                                            - 47 -
shown why the Forest Service’s approach is unreasonable. We therefore defer to the

Forest Service and decline to find it violated the APA when it developed the forest-wide

approach in the Phase II Amendment to create a goshawk-friendly habitat.

                     2) Snag-dependent species

       Biodiversity argues the Phase II Amendment fails to ensure the viability of species

that depend on “snags” in violation of § 219.19 of the 1982 Rule.

       A “snag” is a dead standing tree. See Phase II Amendment Glossary, App. at

2363. Many species depend on snags for shelter, food, or both—such as the Lewis’s

woodpecker, the black-backed woodpecker, the pygmy nuthatch (a bird species), and the

fringed myotis (a bat species). When snags are scarce, snag-dependent species struggle

to survive. Botanists measure the number of snags per acre, or “snag density,” and the

diameter of the snag’s trunk, or “snag size.” See 2005 Final EIS, App. at 1214-15; Phase

II Amendment Glossary, App. Br. at 2317. The Forest Service seeks to manage snag

density and size in the BHNF to ensure the viability of snag-dependent species.

       The 1997 Forest Plan contained snag density and size standards, but the Chief’s

1999 Decision found them “inadequate to assure viability for the [BHNF]’s snag-

dependent [species].” Chief’s 1999 Decision, App. at 2505. The Chief prescribed

detailed snag standards and directed the Forest Service to adopt them. Chief’s 1999

Decision, App. at 2465-66, 2503-05. The Phase I Amendment did so.

       After the BHNF suffered a significant increase in forest fires and mountain pine

beetle infestation, the Forest Service altered its approach to snags in the Phase II

Amendment. See 2005 Revised Forest Plan, App. at 2036, 2090-91. For example, the


                                             - 48 -
Phase II Amendment aims for an average of 3 snags per acre that are greater than 9

inches in diameter, 25 percent of which are greater than 14 inches in diameter. 2005

Revised Forest Plan, App. at 2036.46 If an area does not meet that objective, the Forest

Service must keep all snags. See id. at 2090. The Forest Service must also keep all snags

greater than 20 inches in diameter, unless they are a safety hazard. Id. at 2090. The

Forest Service adopted the Phase II Amendment’s snag standards and objectives to meet

three important goals: (1) “provide for species viability,” (2) “reduce the probability of

large-scale, high intensity fires,” and (3) “reduce susceptibility to bark beetle infestation.”

2005 Record of Decision, App. at 1123-24.

       Biodiversity challenges the Forest Service’s technical and scientific evaluation of

the Phase II Amendment’s snag standards and objectives,47 arguing they fail to ensure the

viability of species. For example, Biodiversity contends that “[e]xperts recommend

roughly 41” snags per acre as optimal for black-backed woodpeckers. Aplt. Br. at 41.48


       46
          This contrasts with the snag management standard in the Chief’s 1999 Decision
to retain either 2 or 4 snags per acre greater than 10 inches in diameter (depending on the
slope’s orientation), 25 percent of which must be greater than 20 inches in diameter.
Chief’s 1999 Decision, App. at 2465; see also Phase I Amendment Decision Notice and
FONSI, App. at 368, 377.
       47
          In addition, Biodiversity attacks the Phase II Amendment’s use of standards and
objectives for snags, as opposed to standards only. Aplt. Br. at 41. It cites no authority,
and its argument that objectives offer less accountability and are less effective at ensuring
the viability of species fails to show how the Phase II Amendment violates the APA.
       48
         The experts’ recommendation of 41 snags per acre is “for burned forest” only.
Conservation Assessment of Woodpeckers in the BHNF, South Dakota and Wyoming,
App. at 932 n.b.



                                             - 49 -
Biodiversity therefore concludes the Phase II Amendment’s snag standard providing for

only 3 snags per acre fails to ensure the viability of this species. Moreover, Biodiversity

argues that pygmy nuthatches “prefer snags of 19 or more” inches in diameter. Aplt. Br.

at 42. Biodiversity concludes the Phase II Amendment’s snag standard providing for

snags 9 inches in diameter, 25% of which are 14 inches in diameter, and retaining all

snags greater than 20 inches, fails to ensure the pygmy nuthatches’ viability in the BHNF.

       Biodiversity’s argument addresses what a species prefers, rather than what a

species needs for viability in terms of snags. It fails to show why we should not defer to

the Forest Service’s technical and scientific expertise. Forest Guardians, 641 F.3d at

442.

       For example, experts told the Forest Service that black-backed woodpeckers prefer

high snag densities produced by fires and mountain pine beetles, but lower snag densities

“provide suitable nesting and foraging habitat” in between fire or beetle outbreaks.

Expert Interview Summary for the BHNF LRMP, App. at 532-33. Moreover, the Phase

II Amendment contains objectives retaining high snag-densities following fires or

infestations. See 2005 Revised Forest Plan, App. at 2066. Expert reports also advised

the Forest Service that although the pygmy nuthatch prefers 19-inch diameter snags, this

species uses a range of snag sizes, including snags as small as 11-inches in diameter. See




                                            - 50 -
Conservation Assessment of the Pygmy Nuthatch in the BHNF, South Dakota and

Wyoming, App. at 1006-07.49

       Relying on this technical and scientific expertise, the Forest Service concluded its

snag standards and objectives would provide sufficient habitat to ensure species viability,

including for the black backed woodpecker, 2005 Final EIS, App. at 1451-52, and the

pygmy nuthatch, 2005 Final EIS, App. at 1399-1400. Biodiversity has not shown why

we should not defer to the Forest Service’s technical or scientific assessment.

       Applying deference to the Forest Service’s reliance on technical or scientific

expertise, we have examined the Phase II Amendment’s analyses for each snag-

dependent species identified by Biodiversity. We conclude Biodiversity has not shown

that the Phase II Amendment as to snag standards and objectives is arbitrary, capricious,

an abuse of discretion, or otherwise contrary to law.

                     3) Sensitive plants

       Biodiversity argues the Phase II Amendment fails to establish “unambiguous”

standards and guidelines to protect the viability of sensitive plants from ground-

disturbing activities such as timber harvesting and other vegetative management. Aplt.

Br. at 44-46; Reply at 22. Biodiversity does not identify any statute, regulation, or case

law to support its argument. Instead, it relies on the Chief’s 1999 Decision and the

       49
          The Forest Service integrated this information into its pygmy nuthatch viability
analysis, noting that “snags greater than 15 inches in diameter are an integral part of
pygmy nuthatch nesting and roosting habitat,” and that providing for snags at least 14
inches in diameter and requiring retention of all snags greater than 20 inches in diameter
would meet the pygmy nuthatch’s habitat needs. 2005 Final EIS, App. at 1339.



                                            - 51 -
Settlement Agreement, which required the Forest Service to promulgate “specific and

unambiguous standards and guidelines” to protect and maintain viability of sensitive

plants. Chief’s 1999 Decision, App. at 2516. But, as noted above, those documents

cannot serve as an independent basis for a violation of the APA.

       Even considering the Chief’s 1999 Decision and the Settlement Agreement as

factors, the Forest Service did not violate the APA. The Phase II Amendment includes

numerous protections for sensitive plants. See 2005 Final EIS, App. at 1202; 2005

Revised Forest Plan, App. at 2104-09, 2111, 2118-19, 2121-24, 2175, 2180, 2184, 2201,

2283. Biodiversity does not argue those protections are arbitrary, capricious, or have no

factual basis. Instead, it contends the protections are unclear and inadequate to protect

sensitive plants. The scope of our APA review is narrow. We do not “substitute our

judgment for that of the agency’s on matters within its expertise,” Colorado Wild,

Heartwood v. USFS, 435 F.3d 1204, 1213 (10th Cir. 2006), including how to protect

sensitive plants.

       Without having more than Biodiversity’s vague and unpersuasive argument that

those protections might have been more restrictive or written more clearly, we cannot

find an APA violation. See also Forest Guardians v. USFS, 329 F.3d 1089, 1099 (9th

Cir. 2003) (“An agency’s actions need not be perfect; we may only set aside decisions

that have no basis in fact, and not those with which we disagree.”). Biodiversity fails to

show how the sensitive plant protections in the Phase II Amendment are arbitrary,

capricious, an abuse of discretion, or otherwise contrary to law.

       b. Protect RNAs and Botanical Areas

       Biodiversity argues the Phase II Amendment fails to comply with the 1982 Rule

requiring the Forest Service to establish and follow heightened protections in two BHNF

areas: Research Natural Areas (“RNAs”) and Botanical Areas.

              i. Protecting RNAs

       Biodiversity contends the Forest Service violated NFMA and the APA by

allowing livestock on RNAs without first having RNA management plans in place. Aplt.

Br. at 49-51, Aplt. Reply Br. at 25-27.

       The 1982 Rule required the Forest Service to establish and protect RNAs. 36

C.F.R. § 251.23 (1982). RNAs must “be retained in a virgin or unmodified condition

except where measures are required to maintain a plant community which the area is

intended to represent.” Id. The Forest Service may “establish a level of acceptable

casual or incidental livestock use that can be tolerated and is consistent with the

management prescription for the research natural area.” Forest Service Manual

§ 4063.3(3); Suppl. App. at 181-82.

       The Forest Service designates RNAs via a multi-step process that takes several

years to complete. As part of this process, the Forest Service must establish boundaries,

maps, and monuments; withdraw those areas from “mineral entry” (disallowing new

mineral rights claims); and create an individualized management plan. See Forest

Service Manual ch. 4060. The regulations do not impose deadlines to complete the RNA

designation process. See id.




                                             - 53 -
      In 2005, the Forest Service conducted a detailed RNA analysis, 2005 Final EIS,

App. at 1526-37, and designated four new RNAs in the BHNF, subject to general RNA

management guidelines and protections, 2005 Revised Forest Plan, App. at 2020, 2176-

2180. The Phase II Amendment directs the Forest Service to prepare individualized

management plans for these RNAs by 2008. 2005 Revised Forest Plan, App. at 2179.

The Forest Service admits it missed that deadline, but reports it is withdrawing the RNAs

from mineral entry and proceeding with the management plan process. Aplee. Br. at 42.

      Biodiversity contends the Forest Service failed to comply with its RNA duties

under NFMA by missing the Phase II Amendment’s internal deadline to complete

individualized management plans and by allowing livestock to trample and graze on

sensitive plants in the RNAs. Aplt. Br. at 49-51, Aplt. Reply Br. at 25-27. Biodiversity

insists that, without individualized management plans, the Forest Service must ban all

livestock in the RNAs because it is impossible to determine whether any use would be

consistent with the management plan for the RNA. Aplt. Br. at 50-51; see also Forest

Service Manual § 4063.3(3).

      The APA “leaves in the courts the discretion to decide whether agency delay is

unreasonable.” Forest Guardians v. Babbitt, 174 F.3d 1178, 1190 (10th Cir. 1999). If an

agency has no “concrete statutory deadline” for agency action and such action is

“governed only by general timing provisions,” such as a general statutory admonition that

agencies complete a task “within a reasonable time,” then “a court must compel only

action that is delayed unreasonably.” Id. at 1190-91 (quotations omitted); see Cobell v.

Norton, 240 F.3d 1081, 1096 (D.C. Cir. 2001) (“An agency’s own timetable for


                                           - 54 -
performing its duties in the absence of a statutory deadline is due considerable

deference.” (quotations omitted)).

       Biodiversity has not shown how the Forest Service’s delay regarding the RNA

management plans is unreasonable. Although completion of the plans is pending, the

Phase II Amendment imposes standards and guidelines to protect sensitive plants forest-

wide, see, e.g., 2005 Revised Forest Plan, App. at 2089, 2099-100, 2109, and includes

additional RNA-specific protections, 2005 Revised Forest Plan, App. at 2179. The Forest

Service has excluded livestock grazing in two of the new RNAs (other than a semi-annual

cattle drive through one RNA), and it has limited livestock grazing in the other two areas

to incidental use. 2005 Final EIS, App. at 1534; Chief’s 2006 Decision, App. at 2715.

The Forest Service also monitors conditions in the RNAs. See Monitoring Reports, App.

2717-940. If livestock use “begins to affect the ecological characteristic[s], the use will

be removed from the RNA.” 2005 Revised Forest Plan, App. at 2179.

       We conclude Biodiversity has not shown the Forest Service acted arbitrarily or

capriciously, abused its discretion, or otherwise violated the law as to RNAs.

              ii. Protecting Botanical Areas

       Biodiversity claims the Phase II Amendment lacks adequate monitoring

requirements to protect sensitive plants in Botanical Areas from livestock damage. Aplt.

Br. at 46-48; Aplt. Reply Br. at 23-24.

       Botanical Areas protect sensitive species and “exhibit plant communities,

associations, and/or individual species of particular interest.” 2005 Revised Forest Plan,

App. at 2183; see also Forest Service Manual § 2372.05(3) (definition). Although not


                                             - 55 -
subject to the same level of regulation and approval as RNAs, they receive protections to

preserve their unique ecological characteristics. Compare Forest Service Manual

§ 2372.2 (Botanical Area designation process) with id. ch. 4060 (RNA designation

process).

       To protect Botanical Areas, the 1997 Forest Plan adopted Standard 3.1-2501,

which allowed livestock grazing in Botanical Areas if it did “not conflict with the values

for which the botanical area was designated.” See Chief’s 1999 Decision, App. at 2515

(describing Standard 3.1-2501 under the 1997 Forest Plan). The Chief’s 1999 Decision

criticized this standard, stating that “Standard 3.1-2501 . . . lacks sufficiently strong

monitoring requirements to quantify impacts to sensitive plants in a manner that would

provide a basis for ensuring that standard is met.” Id.

       In response to this criticism, both the Phase I and Phase II Amendments added

Standard 3.1-2503, which requires the Forest Service to “[r]estrict access of domestic

livestock to protect . . . sensitive and species of local concern plant occurrences in

designated botanical areas.” 2005 Revised Forest Plan, App. at 2185 (same); see also

Phase I Amendment Decision Notice and FONSI, App. at 347. Although livestock may

still graze in Botanical Areas (if not in conflict with the areas’ ecological values), the

Forest Service must “restrict” livestock access if the Botanical Area contains sensitive

plants. See Revised Forest Plan, App. at 2185. When the Forest Chief denied

Biodiversity’s administrative challenge to the Phase II Amendment in 2006, he

determined these standards “provide adequate direction with respect to grazing, which is

consistent with NFMA regulations . . . .” Chief’s 2006 Decision, App. at 2716.


                                              - 56 -
       Biodiversity argues the Phase II Amendment “failed to strengthen monitoring

requirements or other protections,” Aplt. Br. at 48, in violation of the Chief’s 1999

Decision’s directing the Forest Service to strengthen monitoring requirements and the

Settlement Agreement’s promising to remedy “‘all inadequacies identified in the Chief’s

[1999 Decision].’” Aplt. Reply Br. at 24 (quoting Settlement Agreement, App. at 436).50

It contends the Phase II Amendment’s monitoring requirements are too weak to ensure

livestock grazing does not compromise Botanical Areas. Aplt. Reply Br. at 24.

Biodiversity insists that instances of livestock grazing and trampling sensitive plants in

some of the Botanical Areas between 2006 and 2009 prove Standards 3.1-2501 and 3.1-

2503 are not strong enough. Aplt. Br. at 48-49; Aplt. Reply Br. at 23-24.

       Biodiversity’s argument, however, only goes so far. Our APA review “is narrow,”

asking only whether the Forest Service “examine[d] the relevant data and articulate[d] a

satisfactory explanation for its action including a rational connection between the facts

found and the choice made.” Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. State Farm Mut.

Auto. Ins. Co., 463 U.S. 29, 43 (1983) (quotations omitted). We must not “substitute

[our] judgment for that of the agency.” Judulang v. Holder, 132 S. Ct. 476, 483 (2011)

(quotations omitted).


       50
          Although Biodiversity alleges the Forest Service failed to strengthen monitoring
requirements to protect sensitive plants in Botanical Areas “in violation of NFMA,” Aplt.
Br. at 49, it does not cite any NFMA statutory or regulatory authority. Biodiversity cites
only the Chief’s 1999 Decision and the Settlement Agreement. As we have noted, an
APA claim cannot be based on these non-statutory and non-regulatory documents. They
only may be considered as factors in our APA analysis.



                                            - 57 -
       The Forest Service added Standard 3.1-2503 in the Phase I Amendment “[t]o

clarify protection of sensitive plant populations within designated Botanical Areas as per

the Deputy Chief’s direction.” 1997 Revised Forest Plan Corrections or Additions, App.

at 386. It expanded on that rationale in the Phase II Amendment, explaining “the

standard was reworded to clarify that livestock would be restricted access to R2

sensitive . . . plant occurrences.” 2005 Revised Forest Plan, App. at 1522 (also

recognizing Standard 3.1-2503 would be explained in greater detail in the “Forest Plan

Monitoring and Implementation Guide”).51 It further explained that if monitoring shows

livestock access Botanical Areas with sensitive plants, the Forest Service would take

steps to exclude the cattle. See 2005 Final EIS, App. at 1773.

       By adding Standard 3.1-2503 to restrict livestock from Botanical Areas that

contain sensitive plants, the Phase II Amendment does more than strengthen “monitoring

requirements to quantify impacts to sensitive plants,” Chief’s 1999 Decision, App. at

2515—it “[r]estrict[s]” livestock from Botanical Areas that have sensitive plants. 2005

sensitive plants in Botanical Areas between 2006 and 2009, noted livestock damage, and

       Although Biodiversity cites the portions of the monitoring reports about livestock

damaging some sensitive plants in Botanical Areas between 2006 and 2009, Aplt. Br. at

          Although the Forest Service does not define “restrict” in the Phase II
Amendment, it does say in the 2005 Final EIS that if “domestic livestock are not
restricted from accessing” sensitive plants in Botanical Areas under Standard 3.1-2503,
“then method(s) will be implemented to remove the cattle” from those areas. 2005 Final
EIS, App. at 1773; see also id., App. at 1795 (same). And during its discussion of
specific sensitive plant species, the 2005 Final EIS further states, “[i]t is assumed that
restrictions of livestock will be fully implemented and therefore no direct effects would
be associated with livestock use at [highbush cranberry (a sensitive plant)] occurrences
within the designated Biological Areas.” 2005 Final EIS, App. at 1768.

          Claims regarding an agency’s failure to act may proceed under § 706(1) of the
APA, which authorizes courts to “compel agency action unlawfully withheld or
unreasonably delayed.” 5 U.S.C. § 706(1). Such challenges are appropriate, however,

demonstrate based on the monitoring reports how the Forest Service acted arbitrarily or

capriciously when it adopted Standard 3.1-2503 in 2005. Biodiversity makes no

argument the Forest Service failed to examine relevant data or inadequately explained the

rationale for adopting Standards 3.1-2501 and 3.1-2503. See State Farm, 463 U.S. at 43.

       Based on our review of the Phase II Amendment’s protective measures and the

Forest Service’s explanation for their adoption and our weighing the monitoring reports,

Biodiversity has not shown the Forest Service acted arbitrarily or capriciously with

respect to Botanical Areas.

       c. Suitability and capability assessments

       Biodiversity contends the Forest Service did not comply with § 219.20 of the 1982

Rule, which required the Forest Service to conduct a proper suitability and capability

analysis for MIS and livestock grazing in preparing the Phase II Amendment. See 36

C.F.R. § 219.20.

              i. When to conduct a suitability or capability analysis

       The parties dispute when § 219.20 required each type of analysis. Biodiversity

contends § 219.20 required the Forest Service to conduct both a suitability and a

capability analysis for inclusion in the overall forest plan, and do both again for each site-

specific project. Aplt. Reply Br. at 30-31. The Forest Service interprets § 219.20 as

requiring a suitability analysis only at the forest-wide level, and then a capability analysis

only at the project level. See, e.g., Aplee Br. at 44-45 (“The Forest Service makes

suitability determinations at the forest plan level. . . . Capability is verified at the project

level.”). The Phase II Amendment itself takes that position. 2005 Revised Forest Plan,

App. at 2414.

       NFMA directs the Forest Service to “specify guidelines for land management

plans” that “provide for diversity of plant and animal communities based on the

suitability and capability of the specific land area in order to meet overall multiple-use

objectives.” 16 U.S.C. § 1604(g)(3)(B) (emphasis added). Section 219.20 of the 1982

Rule provided further direction, requiring the Forest Service to conduct a suitability and

capability analysis for MIS and grazing:

              In forest planning, the suitability and potential capability of National
       Forest System lands for producing forage for grazing animals and for
       providing habitat for management indicator species shall be determined as
       provided in paragraphs (a) and (b) of this section. Lands so identified shall
       be managed in accordance with direction established in forest plans.

              (a) Lands suitable for grazing and browsing shall be identified and
       their condition and trend shall be determined. The present and potential
       supply of forage for livestock, wild and free-roaming horses and burros,
       and the capability of these lands to produce suitable food and cover for
       selected wildlife species shall be estimated. The use of forage by grazing
       and browsing animals will be estimated. Lands in less than satisfactory
       condition shall be identified and appropriate action planned for their
       restoration.

              (b) Alternative range management prescriptions shall consider
       grazing systems and the facilities necessary to implement them; land
       treatment and vegetation manipulation practices; and evaluation of pest
       problems; possible conflict or beneficial interactions among livestock, wild
       free-roaming horses and burros and wild animal populations, and methods
       of regulating these; direction for rehabilitation of ranges in unsatisfactory
       condition; and comparative cost efficiency of the prescriptions.

36 C.F.R. § 219.20 (1982). The 1982 Rule defined “suitability” and “capability.” Id.

§ 219.3.54

       Section 219.20 did not specify the level at which and how often the Forest Service

must have conducted suitability and capability analyses. The Forest Service states its

interpretation of § 219.20 in the Phase II Amendment:

               The planning regulations at 36 CFR 219.20 requires lands to be
       identified which are capable and suitable for producing forage for grazing
       animals and for providing habitat for indicator species. . . . Capability and
       suitability for grazing and browsing use is presently determined at two
       Forest Service planning levels (i.e. Forest plans (suitability) and project
       plans (AMPs) (capability)).

2005 Revised Forest Plan, App. at 2414.

       Among the reasonable interpretations of § 219.20, the Forest Service’s is one of

them. We will defer to it unless it is “unreasonable, plainly erroneous, or inconsistent

with the regulation’s plain meaning.” Utah Envtl. Cong. v. Troyer, 479 F.3d 1269, 1281

(10th Cir. 2007) (quotations omitted); see Auer v. Robbins, 519 U. S. 452, 461 (1997).

       Biodiversity posits an alternative interpretation, directing us to Western

         “Suitability” was defined as “[t]he appropriateness of applying certain resource
management practices to a particular area of land, as determined by an analysis of the
economic and environmental consequences and the alternative uses foregone. A unit of
land may be suitable for a variety of individual or combined management practices.” 36

       “Capability” was defined as “[t]he potential of an area of land to . . . allow

Idaho Feb. 7, 2006) for the proposition that “forest-wide determinations set up a baseline

against which site-specific determinations must then be made based on site-specific

conditions.” Aplt. Br. at 56.55 It also argues the Forest Service offered contradictory and

inconsistent statements in some of the site-specific project documents regarding whether

to conduct a suitability or capability analysis at the site-specific level. Id. at 54-56.

       These arguments propose an alternative interpretation and criticize the Forest

Service’s ambiguous use of terminology. We find no reason, however, to conclude the

Forest Service’s interpretation is unreasonable, plainly erroneous, or inconsistent with the

regulation. See Decker v. Nw. Envtl. Def. Ctr., 133 S. Ct. 1326, 1337 (2013) (“[A]n

agency’s interpretation need not be the only possible reading of a regulation—or even the

best one—to prevail.”). As a result, we defer to the Forest Service’s interpretation.

              ii. MIS suitability and capability analyses

       Biodiversity alleges the Forest Service did not conduct an adequate suitability or

capability analysis of the selected MIS populations for the Phase II Amendment.56

                      1) MIS suitability analysis

       Biodiversity first argues the Forest Service failed to conduct an adequate MIS

suitability analysis at the forest-planning level. It does not allege the Forest Service

failed to conduct an MIS suitability analysis at the site-specific level.57

       Biodiversity points out that the Phase II Amendment (1) does not contain a formal

MIS suitability analysis and (2) states that “‘[h]abitat capability/suitability models are

available for’ only ‘some management indicator species (MIS), Sensitive Species,

Species of Local Concern and Demand Species.’” Aplt. Br. at 52 (emphasis added)

(quoting 2005 Revised Forest Plan, App. at 2436). This shows, Biodiversity says, the

Forest Service did not conduct an adequate MIS suitability analysis. Id. at 52.

       Although the Forest Service did not conduct a formal suitability analysis on MIS,

it evaluated each MIS’s habitat needs and assessed how various proposed actions might

affect the MIS.58 Each analysis examined the distribution and natural history of each

species, what kind of habitat it favors, conditions and trends in the habitat, population


       57
          Biodiversity contends the Forest Service “failed to determine the suitability and
capability of lands for MIS.” Aplt. Br. at 52. Biodiversity’s arguments, however, are
directed to the lack of forest-wide analyses. See id. at 52-53. To the extent that
Biodiversity challenges the lack of site-specific analyses, that argument is inadequately
developed, and we do not consider it here. See Utah Environmental Congress v.
Bosworth, 439 F.3d 1184, 1194 n.2 (10th Cir. 2006) (“An issue mentioned in a brief on
appeal, but not addressed, is waived.”)

kinglet); id. at 1474-79 (ruffed grouse); id. at 1480-88 (song sparrow); id. at 1489-96

status and trends, how various management activities affect the habitat and population

(such as the ecosystem approach to management, the designation of RNAs, and the

activities designed to reduce the risks of fire and insect infestation), and how the MIS

would be monitored.

       Biodiversity does not explain how these detailed analyses—especially those that

examined the effects of management activities on the MIS—fail to comply with § 219.20.

Biodiversity also does not explain how a lack of some “habitat capability/suitability

models,” 2005 Revised Forest Plan, App. at 2436, renders an MIS suitability analysis

inadequate. Accordingly, Biodiversity has failed to show the Forest Service did not

comply with § 219.20’s mandate to analyze “[t]he appropriateness of applying certain

resource management practices to a particular area of land,” including examining “the

economic and environmental consequences and the alternative uses foregone” concerning

the habitat needed to support the MIS. 36 C.F.R. § 219.3 (1982); see San Juan Citizens

Alliance v. Stiles, 654 F.3d 1038, 1045 (10th Cir. 2011) (“When courts consider [APA]

challenges, an agency’s decision is entitled to a presumption of regularity, and the

challenger bears the burden of persuasion.” (citation omitted)).

                     2) MIS capability analysis

       Biodiversity alleges the Forest Service failed to conduct a forest-wide MIS

capability analysis. See Aplt. Br. at 52-53; Aplt. Reply Br. at 30-31. We defer to the

Forest Service’s interpretation that no such capability analysis was required under

§ 219.20. Biodiversity does not allege the Forest Service failed to conduct an MIS




                                            - 65 -
capability analysis at the site-specific level. Biodiversity’s MIS capability analysis

argument therefore fails.

              iii. Grazing suitability and capability analyses

       The 1982 Rule required the Forest Service to analyze “the suitability and potential

capability” of the land “for producing forage for grazing animals.” 36 C.F.R. § 219.20

(1982). As noted above, the Forest Service conducts a suitability analysis at the forest-

wide level, and then a further capability analysis at the project level. See id. § 219.3;

2005 Revised Forest Plan, App. at 2414. We therefore limit our review to the Forest

Service’s grazing suitability analysis at the forest-wide level and its grazing capability

analysis at the project level.

                      1) Grazing suitability analysis

       Biodiversity contends the Forest Service did not conduct a proper grazing

suitability analysis for the Phase II Amendment because it improperly relied on the 1997

Forest Plan’s grazing suitability analysis. Aplt. Br. at 53, 56.

       The Forest Service conducted a grazing suitability analysis for the 1997 Forest

Plan. 1997 Final EIS, App. at 284-87; 1997 Record of Decision, App. at 324. In 1999,

the Chief determined the “Forest [Service] has performed the suitability determination

and analysis necessary for compliance with NFMA,” and there was no deficiency

“concerning the general issue of livestock grazing suitability.” Chief’s 1999 Decision,

App. at 2537. He did, however, recognize deficiencies in other areas of the 1997 Forest

Plan, and therefore gave “[i]nstructions for further action concerning grazing associated

with riparian areas, sensitive species, and Botanical Areas, [as] provided in the Decision


                                             - 66 -
Summary.” Id.; see also Chief’s 2006 Decision, App. at 2704 (concluding “[l]ivestock

grazing was not identified as a major issue” in the Phase II Amendment).

       Biodiversity argues “[i]n light of the number of issues identified by the Chief [in

1999] regarding livestock and sensitive plants, grazing suitability falls within the scope of

the Phase II Amendment,” and the Forest Service should have conducted a new grazing

suitability analysis. Aplt. Reply Br. at 27. Biodiversity’s assessment, however,

overstates the Chief’s concerns with livestock grazing.

       The Chief’s 1999 Decision focused on four “primary deficiencies of concern,”

none of which contemplated extensive changes to livestock grazing. See Chief’s 1999

Decision, App. at 2462 (identifying the primary deficiencies as: (1) “[v]iability

determinations for some species,” (2) “[s]tandards and guidelines to maintain viability of

some species,” (3) “[m]anagement indicator species (MIS) requirements,” and

(4) “[m]onitoring direction for some sensitive species”). As a result, consistent with the

Chief’s 1999 Decision, the Phase II Amendment contains limited changes to grazing and

no major changes at the forest-wide level. See 2005 Record of Decision, App. at 1126-

27; see id. at 1123-31 (describing the rationale for the Phase II Amendment, which does

not contemplate major changes to livestock grazing); id. at 1156 (describing purpose of

the Phase II Amendment, which does not include modifying livestock grazing allotments

forest-wide). The Phase II Amendment addresses grazing suitability mostly by repeating

the Forest Service’s 1997 analysis. See 2005 Revised Forest Plan, App. at 2414-16.

       Biodiversity has not shown how the Forest Service’s treatment of grazing in the

Phase II Amendment violates the APA. The 1982 Rule required the Forest Service to


                                            - 67 -
conduct a grazing suitability analysis. 36 C.F.R. § 219.20 (1982). It did so in 1997.

Neither the Chief’s 1999 Decision nor the Phase II Amendment identified grazing as one

of the major issues for revision, nor did they contemplate modifying grazing activities

forest-wide. Instead, grazing was considered in conjunction with other issues, such as

addressing additional measures to protect sensitive plants and animals “in areas with

ongoing livestock grazing activities.” Chief’s 1999 Decision, App. at 2463.

       Biodiversity fails to show how the Phase II Amendment’s reliance on the 1997

grazing suitability analysis and its changes to the 1997 Forest Plan grazing were arbitrary,

capricious, an abuse of discretion, or otherwise contrary to law.

                      2) Grazing capability analysis

       Biodiversity also argues the Forest Service did not conduct proper grazing

capability analyses for four site-specific projects.59 It contends the Forest Service either

omitted or inadequately addressed the issue because the site-specific project documents

contain inconsistent statements about whether to conduct a suitability or capability

analysis at the site-specific level. Aplt. Br. at 53-56.

       A grazing capability analysis examines a project area to determine “[t]he potential

of an area of land to” produce forage “at a given level of management intensity” subject

to conditions at the site. 36 C.F.R. § 219.3 (1982).

       Each project includes an EIS or EA that contains a grazing capability analysis or

incorporates it by reference. See Bearlodge Range Project EA, App. at 3022-30

4372-4404 (including a grazing “capability assessment”); North Zone 05 Project Final

EIS, App. at 4826, 4944 (stating “[r]angeland analysis and inventories were conducted”

and the Forest Service analyzed which acres “were capable for grazing”); North Zone 08

Project EA, App. at 5179, 5218-52 (incorporating by reference a “Range Specialist

Report” and summarizing the range capability analysis). We agree with Biodiversity that

the Forest Service could have used the terms “suitability” and “capability” more clearly,

but that shortcoming does not amount to an APA violation.

       Biodiversity has not shown how the Forest Service’s actions regarding capability

analyses in the four challenged site-specific projects were arbitrary, capricious, an abuse

of discretion, or otherwise contrary to law.

                                    D. NEPA Issues

       Biodiversity challenges the Wyoming federal district court’s conclusion that the

Phase II Amendment complies with NEPA. It contends the Forest Service violated

NEPA in three ways: by failing to (1) consider a reasonable range of alternatives in the

Final EIS because it did not include a “no grazing” alternative; (2) take a “hard look” at

how the Phase II Amendment would affect sedimentation in the BHNF’s waterways,

including how the sedimentation might affect sensitive plants and aquatic fauna; and

(3) take a “hard look” at historical grazing practices before re-authorizing grazing use in

the Phase II Amendment.


                                               - 69 -
1. Reasonable Range of Alternatives

       Biodiversity argues the Phase II Amendment’s Final EIS should have included a

forest-wide “no grazing” alternative. Aplt. Br. at 59-60; Aplt. Reply Br. at 32. We

disagree because that alternative fell outside the main purposes of the Phase II

Amendment.

       “Under NEPA, an EIS prepared by a federal agency must include a discussion of

‘alternatives to the proposed action.’” Wyoming v. USDA, 661 F.3d 1209, 1243 (10th

Cir. 2011) (quoting 42 U.S.C. § 4332(2)(C)(iii)). The agency must “[r]igorously explore

and objectively evaluate all reasonable alternatives” for the proposed action in response

to a “specif[ied] underlying purpose and need.” 40 C.F.R. §§ 1502.13, 1502.14(a); see

also Wyoming, 661 F.3d at 1243. The range of reasonable alternatives must at least

include the alternative of taking “no action.” 40 C.F.R. § 1502.14(d).

       The range of reasonable alternatives “is not infinite.” Utahns for Better Transp. v.

U.S. Dep’t of Transp., 305 F.3d 1152, 1166 (10th Cir. 2002); see also Vermont Yankee

Nuclear Power Corp. v. Natural Res. Def. Council, Inc., 435 U.S. 519, 551 (1978)

(“Common sense also teaches us that the ‘detailed statement of alternatives’ cannot be

found wanting simply because the agency failed to include every alternative device and

thought conceivable by the mind of man.”). “[O]nce an agency establishes the objective

of the proposed action—which it has considerable discretion to define—the agency need

not provide a detailed study of alternatives that do not accomplish that purpose or

objective, as those alternatives are not ‘reasonable.’” Wyoming, 661 F.3d at 1244

(citations omitted); see also Biodiversity Conservation Alliance v. Bureau of Land Mgmt.,

608 F.3d 709, 715 (10th Cir. 2010) (“The [agency] may eliminate alternatives that . . . do

not meet the purposes and needs of the project.”)

       When we review an EIS under the APA to determine whether an agency acted

arbitrarily or capriciously by not considering certain alternatives, a “rule of reason and

practicality” informs the analysis. Airport Neighbors Alliance, Inc. v. United States, 90

F.3d 426, 432 (10th Cir. 1996). We ask whether the agency selected and considered a

range of alternatives “sufficient to permit a reasoned choice among the options.”

Wyoming, 661 F.3d at 1243 (quotations omitted). The “rule of reason” considers both the

range of alternatives and the extent the agency discusses the selected alternatives. Utahns

for Better Transp., 305 F.3d at 1166; see also Envtl. Def. Fund, Inc. v. Andrus, 619 F.2d

1368, 1375 (10th Cir. 1980) (“The discussion of environmental effects of all alternatives

need not be exhaustive, but it must be such that sufficient information is contained

therein to permit a ‘rule of reason’ designation of alternatives beyond the primary

proposal.”).

       The Chief’s 1999 Decision identified the four “primary deficiencies” in the 1997

Forest Plan as: (1) “[v]iability determinations for some species,” (2) “[s]tandards and

guidelines to maintain viability of some species,” (3) “[m]anagement indicator species

(MIS) requirements,” and (4) “[m]onitoring direction for some sensitive species.”

Chief’s 1999 Decision, App. at 2462. The Chief said the Forest Service should address

grazing only “relative to the deficiencies identified” in his 1999 Decision, including

ensuring sensitive plants were adequately protected. Id. at 2466. The inadequacies

identified by the Chief in 1999 did not contemplate cessation or other major changes to


                                             - 71 -
livestock grazing. The Settlement Agreement did not mention livestock. See Settlement

Agreement, App. at 418-47. And as noted by the Chief in 2006, the Phase II Amendment

did not identify livestock grazing “as a major issue.” Chief’s 2006 Decision, App. at

2704.

        The 2005 Final EIS summarized the scope of the Phase II Amendment:

(1) “[c]ompl[y] with the Chief’s October 1999 [Administrative] Appeal Decision” and

correct various deficiencies in the 1997 Forest Plan by ensuring the viability of species,

following MIS requirements, and creating monitoring objectives for sensitive species;

(2) “[f]ulfill[] components of the 2000 Settlement Agreement to complete an analysis of

candidate RNAs . . . and evaluate the viability of MIS and northern goshawk”; and

(3) “[m]odify[] management direction for fire hazard and insect risk to address both

species viability and diversity and effects on resources, human safety, and

property . . . .’” 2005 Final EIS, App. at 1156; see also id. at 1159-60.60

        Within this scope, the Forest Service considered two “no action” (1 and 2) and

four “action” alternatives (3 to 6):

    Alternative 1 would re-implement the 1997 Forest Plan;
    Alternative 2 would allow the Phase I Amendment to continue without
     modification, including keeping grazing levels the same;
    Alternative 3 would provide diversity by creating ideal habitat forest-wide;
    Alternative 4 would create dense, mature forest conditions forest-wide;
    Alternative 5 would allow timber harvest to equal annual timber growth;
     and


        60
      Biodiversity does not challenge the Forest Service’s definition of the Phase II
Amendment’s scope.



                                             - 72 -
    Alternative 6 would aggressively reduce fire and insect hazards while at the
     same time provide ideal habitat for species forest-wide.

See 2005 Record of Decision, App. at 1133-34; see also 2005 Final EIS, App. at 1201-06

(providing a detailed summary of the six alternatives as they relate to the scope of the

Phase II Amendment).

       Each alternative addressed livestock. See 2005 Final EIS, App. at 1591-92

(summarizing the proposed changes to livestock management under each alternative).

For example, Alternative 6 proposed installing structures to protect ponds containing

leopard frogs, prohibiting livestock from watering within hardwood groves, and

restricting livestock access to Botanical Areas containing sensitive plants. Id. None of

the alternatives contemplated major changes to livestock grazing forest-wide. See id.61

       Biodiversity argues Alternative 2 was not enough to comply with NEPA’s “no

action alternative” requirement because the Forest Service should have considered a no

grazing option “forest-wide.” Aplt. Br. at 59-60; Aplt. Reply Br. at 32.62 Biodiversity

relies on Western Watersheds Project v. Rosenkrance, No. 4:09-CV-298-EJL, 2011 WL

39651, at *10-11 (D. Idaho Jan. 5, 2011), which addressed a challenge to the Bureau of

Land Management’s (“BLM”) decision to grant several livestock grazing permits. The

       61
          The Forest Service declined to consider an alternative that would “[s]top
commercial development . . . (e.g., timber sales, domestic livestock grazing, and other
resources or services from the national forests).” The Forest Service stated those
activities are “a basic component of national forest management policy,” and “[c]hanging
this national policy is outside the scope of the Phase II Amendment . . . .” 2005 Final
EIS, App. at 1199.
       62
            Biodiversity does not address Alternative 1.



                                              - 73 -
plaintiff argued the agency failed to consider a no grazing “[n]o [a]ction [a]lternative.”

Id. at *1-2 (quotations omitted). The district court agreed, reasoning that a “real no

action alternative” would consider allowing “old grazing permits [to] expire” and not

allowing “new permits [to] issue,” thereby ceasing grazing altogether. Id. at 10.

Biodiversity argues a similar analysis should have happened here. Aplt. Br. at 59-60.

       Biodiversity’s argument is misplaced. Western Watersheds is distinguishable

because the only purpose of the BLM’s grazing allotment decision was to determine

whether grazing permits should be issued. Livestock grazing was the centerpiece of the

agency action. See id. at *1-2. By contrast, changing forest-wide grazing was not a

major purpose of the Phase II Amendment. See 2005 Final EIS, App. at 1591-92; see

also Chief’s 2006 Decision, App. at 2704 (recognizing that “[l]ivestock grazing was not

identified as a major issue” in the Phase II Amendment).

       The scope of the Phase II Amendment did not call for consideration of a no

grazing alternative. After “an agency establishes the objective of the proposed

action . . . the agency need not provide a detailed study of alternatives that do not

accomplish that purpose or objective . . . .” Wyoming, 661 F.3d at 1244 (citations and

quotations omitted); see, e.g., Biodiversity, 608 F.3d at 716-17 (concluding the BLM did

not need to consider a proposed alternative that “would not meet the project’s purposes”).

The purpose of the Phase II Amendment was to remedy deficiencies identified in the

Chief’s 1999 Decision, fulfill components of the 2000 Settlement Agreement, and

address fire hazard and insect infestation concerns. 2005 Final EIS, App. at 1156; see

also 2005 Record of Decision, App. at 1123-31. The Forest Service addressed grazing


                                             - 74 -
when relevant to those purposes, see 2005 Final EIS, App. at 1591-92, but a forest-wide

no grazing alternative fell outside the scope of the Phase II Amendment.

       The Forest Service’s choice of NEPA alternatives met the rule of reason. Its

omitting a no grazing alternative was not arbitrary or capricious.

2. Hard Look at Sedimentation Policies

       Biodiversity argues the Forest Service did not rigorously evaluate how the Phase II

Amendment would affect sedimentation and therefore did not meet NEPA’s “hard look”

requirement.63

       NEPA requires agencies to identify adverse effects of proposed agency actions on

the environment. 42 U.S.C. § 4332(2)(C)(i) & (ii). Agencies must “take a ‘hard look’ at

the environmental consequences of proposed actions utilizing public comment and the

best available scientific information.” Colorado Envtl. Coal. v. Dombeck, 185 F.3d 1162,

1171 (10th Cir. 1999) (quoting Robertson v. Methow Valley Citizens Council, 490 U.S.

332, 350 (1989)). An agency meets the “hard look” requirement when it has “made a

reasoned evaluation of the available information and its method was not arbitrary or

capricious.” Utah Shared Access Alliance v. USFS, 288 F.3d 1205, 1213 (10th Cir.


       63
          “Sedimentation” is the accumulation of gravel, sand, silt, and other particulates
in streams and lakes. See Phase II Amendment Glossary, App. at 2360 (defining
sediment). Nature can cause it, but human and livestock activities, such as motorized
vehicles, mining, and overgrazing, can accelerate it. See 2005 Final EIS, App. at 1266-
67, 1385, 1440-41. Sedimentation threatens some plant and animal species, especially
fish. See id. at 1267, 1440-41. For example, the Phase II Amendment discusses the
threats of sedimentation to the American dipper (a bird) and the lake chub (a fish). Id. at
1385, 1875.



                                            - 75 -
2002). A “hard look” seeks to ensure the “agency did a careful job at fact gathering and

otherwise supporting its position.” New Mexico ex rel. Richardson, 565 F.3d at 704

(quotations omitted).

       Biodiversity contends the Forest Service inadequately evaluated whether its two

proposed methods of sedimentation mitigation in the Phase II Amendment—Watershed

Conservation Practices Handbook (“WCPH”)64 and Best Management Practices

(“BMPs”)65—will mitigate the impacts of sedimentation in lakes and streams caused by

livestock, timber harvesting, mining, road construction, and recreation. Aplt. Br. at 62-

63. The record indicates otherwise. The Forest Service looked hard at how the WCPH

and the BMPs would mitigate sedimentation.

       First, the Forest Service explained how the WCPH provides “proven watershed

conservation practices to protect soil, aquatic, and riparian systems,” 2005 Final EIS,

App. at 1268, that “conserve and enhance riparian and wetland ecosystems on the

[BHNF],” id. at 1254. Based on the effective use of WCPH mitigation practices since



       64
          The WCPH contains numerous detailed standards “to protect soil, aquatic, and
riparian systems,” including “hydrologic function, riparian areas, sediment control, soil
productivity, and water purity.” Watershed Conservation Practices Handbook, App. at
4645; see also id. at 4644-66.
        For example, it directs the Forest Service to “[a]void season-long grazing in
riparian areas and wetlands” and “[a]pply short-duration grazing as feasible (generally
less than 20 days) to provide greater opportunity for regrowth . . . .” Id. at 4649.
       65
         In 2005, BMPs were defined as “management practices to prevent or reduce the
pollution of ‘waters of the United States,’” such as “practices to control plant site runoff.”
40 C.F.R. § 122.2 (2005).



                                             - 76 -
1996, the Forest Service incorporates the WCPH “verbatim into forest plans as

standards.” Id. at 1268.

       Second, regarding BMPs, the Final EIS recognized that certain human and

livestock activities could cause sedimentation, but explained how BMPs would help

mitigate the effects. See, e.g., 2005 Final EIS, App. at 1267-68. The Forest Service cited

how BMPs had been used effectively in other national forests and compared those

practices to relevant areas in the BHNF, id. at 1268. It determined that “the

implementation of BMPs [in the BHNF] . . . will be as effective or more effective at

preventing erosion . . . as those studied [in other areas] because of the less erodible soil

types, the seasonal rainfall pattern, and the gentler topography existing [in the BHNF].”

Id. The Final EIS also noted that evaluations conducted in 2001 showed the BMPs in the

BHNF effectively mitigated sedimentation. 2005 Final EIS, App. at 1662. One such

sedimentation evaluation had a “91 percent incidence of meeting or exceeding BMP

application standards and a 96 percent effectiveness in providing adequate protection”

against sedimentation. Id.

       We conclude the Forest Service made a reasoned evaluation of how the WCPH

and the BMPs would mitigate sedimentation under the Phase II Amendment, and reliance

on these methods was not arbitrary or capricious. Biodiversity has not shown that the

Forest Service failed to meet NEPA’s “hard look” requirement.

3. Hard Look at Historical Grazing Practices

       Biodiversity also argues the Forest Service violated NEPA by failing to take a

“hard look” at the effects of past grazing projects before approving four site-specific


                                             - 77 -
grazing projects.66 Aplt. Br. at 64. It contends the Forest Service “‘should disclose the

history of success and failure of similar projects’” to meet NEPA’s “hard look”

requirement. Aplt. Br. at 64 (quoting Sierra Club v. Morton, 510 F.2d 813, 824 (5th Cir.

1975)). Biodiversity has not carried its burden because it does not explain why

considering past grazing information merits inclusion or is reasonably necessary for the

evaluation of each project. See Wyoming, 661 F.3d at 1251 (stating the Forest Service

need not discuss impacts more than “reasonably necessary under the circumstances for

evaluation of the project.” (quotations omitted)); see also San Juan Citizens Alliance v.

Stiles, 654 F.3d 1038, 1045 (10th Cir. 2011) (noting the “challenger bears the burden of

persuasion”).

       Even if the Forest Service were required to consider past grazing practices for the

four site-specific projects, the record indicates it did so. See Bearlodge Range Project

Final EIS, App. at 2999-3000 (noting the project analyzed the “cumulative effects” of

“past human actions” by “focusing on the current aggregate effects of past actions

without delving into the historical details of individual past actions”); Mystic Range

Project Final EIS, App. at 4368 (same); North Zone 05 Project Final EIS, App. at 4776

(same); North Zone 08 Project Final EIS, App. at 5179 (same).

                                            - 78 -
       In sum, Biodiversity has not shown the Forest Service failed to meet the hard look

requirement as to the four site-specific projects, nor has it shown arbitrary or capricious

action in consideration of the four site-specific projects.

                      III. DISCUSSION—COLORADO APPEAL

       After losing in Wyoming, Biodiversity attempted to reopen the Colorado litigation

in May 2013 by filing a motion to enforce the Settlement Agreement and compel the

Forest Service to prepare a Phase II Amendment that complies with NFMA, the 1982

Rule, the Chief’s 1999 Decision, and the Settlement Agreement. See Mot. to Enforce

Settlement Agreement, App. at 150, 159-60. The district court denied the motion based

on laches, reasoning that Biodiversity had waited too long to enforce the Settlement

Agreement. Order Den. Mot. to Enforce Settlement Agreement, App. at 247, 253-54.

Biodiversity argues on appeal the district court abused its discretion. See Aplt. Br. at 66-

77.

       We (A) describe relevant facts and procedure; (B) review the law of laches and

our standard of review; and (C) address Biodiversity’s argument.

                        A. Factual and Procedural Background

1. The Settlement Agreement

       In August 2000, the Forest Service and Biodiversity settled litigation involving the

Beaver Park timber sale. Settlement Agreement, App. at 418-47. In a section titled

“Phase II Forest Plan Amendment defined,” the Settlement Agreement said:

              In the Phase II Forest Plan amendment the Forest Service shall
       amend current management direction—including forest-wide standards and
       guidelines—with appropriate public involvement to ensure compliance


                                             - 79 -
       with requirements of NFMA, its implementing regulations and agency
       policy, and all inadequacies identified in the Chief’s appeal decision of
       October 12, 1999 for the remainder of the life of the Forest Plan Revision,
       except as otherwise amended pursuant to applicable law. Phase II shall
       address all of the issues identified in paragraphs 2, 3, and 4 of this
       settlement agreement, including northern goshawk, Management Indicator
       Species, and Research Natural Areas.

Settlement Agreement § 9(a), App. at 436.

2. Administrative Challenges to the Phase II Amendment

       In October 2005, the Forest Service promulgated the Phase II Amendment, which

Biodiversity challenged in May 2006. See Administrative Appeals, App. at 2581, 2600-

01, & 2612. Biodiversity argued, in part, the Phase II Amendment violated the

Settlement Agreement. See Administrative Appeals, App. at 2583-84, 2604, 2606, 2609,

2615, 2617 n.1, 2619, 2663-64, 2683-2686.

       On November 1, 2006, the Forest Chief denied this administrative challenge,

stating in part that the Forest Service had considered the Settlement Agreement when it

promulgated the Phase II Amendment. Chief’s 2006 Decision, App. at 2698-99, 2704.

Biodiversity then challenged nine site-specific projects implemented under the Phase II

Amendment. During some of those administrative challenges, Biodiversity alleged

violations of the Settlement Agreement.67 Each was denied. See supra notes 22-24 and

accompanying text.


       67
          Biodiversity argued the Forest Service violated the Settlement Agreement in at
least five of its administrative challenges to the site-specific projects. Biodiversity’s
Dean Project Admin. Appeal, App. at 3831 (June 26, 2006) (“In light of all the
aforementioned deficiencies in the [2005 Final EIS] and the Regional Forester’s [2005
Record of Decision], the Phase II Amendment fails to live up to the USFS’s promises as
                                                                                Continued . . .

3. Wyoming Litigation

       Even though Biodiversity had already alleged Settlement Agreement violations in

its administrative challenges, on January 31, 2011, it sent “notice to the Forest Service

that . . . the Forest Service has breached the [Settlement A]greement.” Notice of Breach,

App. at 167. The Forest Service declined to negotiate.

       In October 2011, Biodiversity petitioned the Wyoming federal district court for

review of the Phase II Amendment under the APA. See Pet. for Review, App. at 25, 31.

Biodiversity alleged the Phase II Amendment “violates the September 6, 2000 Settlement

Agreement . . . .” Id. at 31.

       In November 2012, the district court denied Biodiversity’s APA challenge. See

Order Den. Pet., App. at 76. It noted Biodiversity had requested “declaratory and

injunctive relief vacating and setting aside” the Phase II Amendment until it complied

with the Chief’s 1999 Decision and the Settlement Agreement. Id. at 95, 97. The district

court said it “lack[ed] subject matter jurisdiction to address alleged violations of these

Cont.
set forth in the Settlement Agreement in Civil Action No. 99-N-2173.”); Biodiversity’s
Moskee Project Admin. Appeal, App. at 4270 (Oct. 29, 2007) (“[T]he Phase II
Amendment violates the Settlement Agreement by failing to address and fix the
following flaws in the 1997 Revised BHNF LRMP as identified in the Chief’s 1999
Appeal Decision . . . .”); Biodiversity’s Citadel Project Admin. Appeal, App. at 3402
(Oct. 29, 2007) (arguing the Forest Service’s actions were “in complete contradiction of
the Settlement Agreement”); Biodiversity’s Telegraph Project Admin. Appeal, App. at
6342 (Aug. 24, 2009) (“[T]he Phase II Amendment fails to comply with key paragraphs
of the Settlement Agreement.”); Biodiversity’s Rattlesnake Project Admin. Appeal, App.
at 5788 (July 2, 2010) (“[T]he Phase II Amendment itself is illegal and does not comply
with the applicable 1982 implementing regulations, 1999 Appeal Decision, or 2000
Settlement Agreement . . . .”).

documents because neither independently provide [Biodiversity] with appealable issues

under the APA.” Id. at 95.

       In April 2013, the district court reiterated its reasoning when it denied

Biodiversity’s motion for reconsideration. See Order Den. Mot. for Reconsideration,

App. at 148-49 (“Petitioners have cited no authority supporting the novel proposition that

any federal district court other than the District of Colorado could properly exercise

ancillary jurisdiction to enforce the agreement.”).

4. The Motion to Enforce the Settlement Agreement in Colorado and Dismissal
   Based on Laches

       One month later, on May 31, 2013, Biodiversity moved to enforce the Settlement

Agreement in the Colorado federal district court, arguing the Forest Service breached by

failing to promulgate a Phase II Amendment that “compl[ied] with the 1982 Rule” and

“repair[ed] all inadequacies identified” in the Chief’s 1999 Decision. Mot. to Enforce the

Settlement Agreement, App. at 150, 159 (quotations omitted).

       The district court denied the motion based on laches, concluding Biodiversity had

sat on its contract rights too long. See Order Den. Mot. to Enforce the Settlement

Agreement, App. at 247, 253. The district court said laches is appropriate when the delay

is unreasonable and prejudiced the defendant. Id. at 251. It concluded Biodiversity could

have brought its claim at least as early as November 1, 2006—the day the Forest Chief

denied Biodiversity’s administrative appeal of the Phase II Amendment. The district

court said:

       [Biodiversity] knew or should have known by at least November 1, 2006,
       that Phase II would be implemented as set forth in the 2005 [Record of


                                             - 82 -
       Decision], that is, without the provisions here claimed the agreement
       required be included. Their claim that such failure constituted a breach of
       the terms of the Settlement Agreement therefore was fully ripe at that time,
       and their failure to seek a judicial remedy of that alleged breach until years
       later constitutes the type of unreasonable delay which the equitable doctrine
       of laches was intended to address.

Id. at 252.

       The district concluded the six-and-a-half year delay between November 2006 and

May 2013 was unreasonable because Biodiversity “offer[ed] little explanation of their

activities relevant to pursuing available remedies during this appreciable lapse of time.”

Id. Biodiversity’s argument that it “could not immediately challenge the Phase II

Amendment but instead exhausted their administrative remedies on a number of site-

specific projects implementing Phase II,” was unpersuasive because “[Biodiversity]

provide[d] not a shred of evidence to substantiate these bald, global assertions.” Id.

(quotations omitted).

       The district court also determined the delay prejudiced the Forest Service: “the

Forest Service has managed the BHNF in accordance with the Phase II [A]mendment,

with no apparent indication that plaintiffs believed such implementation to constitute a

violation of the Settlement Agreement.” Id. at 253. The court mentioned the Forest

Service had undertaken significant efforts to implement the Phase II Amendment, such as

thinning trees to reduce insect infestation and fire risks. Id. It concluded “any delay in

implementing” the Phase II Amendment’s measures controlling these threats “poses a

significant risk not only to the forest itself, but to property and persons located adjacent to

it.” Id.

                    B. Standard of Review and Legal Background

1. Standard of Review

       We review a district court’s laches decision for abuse of discretion. “Whether

laches bars an action in a given case . . . ‘is a question primarily addressed to the

discretion of the trial court.’” Burnett v. New York Cent. R.R. Co., 380 U.S. 424, 435

(1965) (quoting Gardner v. Panama R.R. Co., 342 U.S. 29, 30-31 (1951) (per curiam)).

On appeal, “we may not disturb the trial court’s ruling in the absence of abuse of that

discretion.” Brunswick Corp. v. Spinit Reel Co., 832 F.2d 513, 523 (10th Cir. 1987);

Mile High Indus. v. Cohen, 222 F.3d 845, 857 (10th Cir. 2000) (same). “We review the

district court’s factual findings as to [a defendant’s] equitable defenses under the clearly

erroneous standard, and its legal conclusions de novo.” Mile High, 222 F.3d at 859; see

also Bermuda Exp., N.V. v. M/V Litsa, 872 F.2d 554, 557 (3d Cir. 1989) (“Our standard

of review on the laches issue has various components. We review factual findings such

as length of delay and prejudice under the clearly erroneous standard; we review the

district court’s balancing of the equities for abuse of discretion; and our review of legal

precepts applied by the district court in determining that the delay was excusable is

plenary.”).68


       68
         The parties agree we should review the laches decision here for abuse of
discretion. See Aplt. Br. at 66-77; Aplee. Br. at 56-57; Aplt. Reply Br. at 34-35, 37.
Although summary judgment based on laches was reviewed de novo in Jacobsen v.
Deseret Book Co., 287 F.3d 936, 948 (10th Cir. 2002) and Hutchinson v. Pfeil, 105 F.3d
562, 564 (10th Cir. 1997), the standard of review for summary judgment is typically de
novo, e.g., Adler v. Wal-Mart Stores, Inc., 144 F.3d 664, 670 (10th Cir. 1998), this appeal
does not arise from summary judgment, and the clear weight of authority is that circuit
                                                                              Continued . . .

2. Legal Background

       The laches defense bars a party’s dilatory claim. Nat’l R.R. Passenger Corp. v.

Morgan, 536 U.S. 101, 121-22 (2002); Jicarilla Apache Tribe v. Andrus, 687 F.2d 1324,

1338 (10th Cir. 1982).69 It stems from the principle that “equity aids the vigilant and not

those who slumber on their rights.” Kansas v. Colorado, 514 U.S. 673, 687 (1995)

(quotations omitted); see also Bowman v. Wathen, 42 U.S. 189, 193 (1843) (“[A] court of

equity . . . has always refused its aid to stale demands, where the party has slept upon his

rights for a great length of time.” (quotations omitted)). Laches bars a claim when there

is: “(1) lack of diligence by the party against whom the defense is asserted, and

(2) prejudice to the party asserting the defense.” Nat’l R.R. Passenger Corp., 536 U.S. at

121-22 (quotations omitted).

       Courts apply the delay and prejudice elements with flexibility. As the Supreme

Court noted, “[e]quity eschews mechanical rules; it depends on flexibility. Equity has

acted on the principle that laches is not, like limitation, a mere matter of time; but

principally a question of the inequity of permitting the claim to be enforced . . . .”

is appropriate depends on “the peculiar equitable circumstances” in each case); Bechler v.

Kaye, 222 F.2d 216, 219 (10th Cir. 1955) (“In the final analysis each case must be

determined upon its own circumstances and whether or not the doctrine of laches should

be applied will be determined from the equities as shown by the evidence.”).

       Courts have said the “lack of diligence” element was met when delay was

“inexcusable,” “unreasonable,” or “undue;”70 and the “prejudice” element was met when

prejudice was “undue,” “substantial,” or “material.”71 Further, courts have said that

prejudice is established when the defendant has expended substantial time and effort

during the delay that the defendant’s claim could defeat. See, e.g., Jicarilla, 687 F.2d at

1338-39 (noting that if the plaintiffs’ delayed NEPA claim were successful and would

thereby cancel defendants’ leases, defendants would be prejudiced because of

expenditures to improve the land and the “loss of future profits”); Southside Fair Hous.

United States, 21 F.3d 895, 913-14 (9th Cir. 1994) (affirming a district court’s

application of laches because plaintiffs brought a claim “[o]nly after substantial work on

the [project] had been completed,” resulting in “undue prejudice” to the Forest Service);

power line, and result in power shortages during the rerouting); see also Park Cnty. Res.

on other grounds by Vill. of Los Ranchos De Albuquerque v. Marsh, 956 F.2d 970, 973

(10th Cir. 1992) (en banc).

       In litigation brought under environmental federal statutes, laches “is disfavored

because of the interests of the public in environmental quality and because the agency

would escape compliance with NEPA if laches were generally applied, thus defeating

Congress’ environmental policy.” Jicarilla, 687 F.2d at 1338-39. As we further

explained in Park County, “laches must be invoked sparingly in environmental cases

because ordinarily the plaintiff will not be the only victim of alleged environmental

damage. A less grudging application of the doctrine might defeat Congress’s

environmental policy.” 817 F.2d at 617 (quotations omitted).




                                            - 87 -
       In Park County, we said that if a district court “fails to consider the legal standard

disfavoring laches . . . . [t]his failure amounts to an abuse of discretion.” Id. If a district

court misapprehends the law in assessing a laches defense, the appellate court may

remand for application of the correct standard, especially if further factual development is

necessary. Id. at 617-18. Some circuit courts, however, have resolved the laches issue on

appeal in cases brought under environmental statutes when the factual record is

sufficiently developed. Id.; accord Apache Survival Coal., 21 F.3d at 906-07.

                                        C. Analysis

       Biodiversity claims the district court abused its discretion in three ways:

(1) failing to consider the precedent disfavoring laches in environmental cases;

(2) erroneously determining Biodiversity’s delay was unreasonable; and (3) improperly

concluding the delay prejudiced the Forest Service.

1. Failure to Consider Laches Is Disfavored

       In its memorandum opinion and order dismissing the case based on laches, the

district court said:

       I note that [Biodiversity]’s claims in this suit do not arise under the NFMA
       or any other environmental statute; instead, they seek to enforce a contract.
       Therefore, whatever administrative or other remedial actions plaintiffs may
       have been required to undertake pursuant to any such environmental
       statutes are not relevant in considering their rights to enforce the terms of
       the Settlement Agreement.

Order Den. Mot. to Enforce Settlement Agreement, App. at 252.




                                              - 88 -
        Biodiversity argues the district court “fail[ed] to acknowledge this is an

environmental case, and that in such cases, application of the doctrine of laches is

disfavored.” Aplt. Br. at 69. This argument misreads the district court in two ways.

        First, to assert the district court “fail[ed] to acknowledge this is an environmental

case” is implausible—the district court’s rulings and analysis since Biodiversity filed its

complaint in 1999 demonstrate it clearly understood the environmental nature of this

case.

        Second, as to acknowledging whether laches should be disfavored, the district

court correctly noted that Biodiversity’s motion to enforce the Settlement Agreement is a

breach of contract claim, not an APA claim based on NFMA, NEPA, or any other

environmental statute. See Order Den. Mot. to Enforce Settlement Agreement, App. at

252. As such, administrative actions that must precede the usual environmental statutory

claim are unnecessary. Rather than failing to acknowledge “the doctrine of laches is

disfavored,” Aplt. Br. at 69, the district court, having received briefs from two parties

making this very point about the doctrine and citing two cases applying it,72 said any

administrative exhaustion rationale to disfavor laches does not apply—is “not relevant”—

        72
          See Intervenors’ Opp’n to the Mot. to Enforce, App. at 182 (“Laches is invoked
‘sparingly’ in environmental litigation, but it does apply when the movant has engaged in
unreasonable delay and the nonmovant has relied extensively on the project at issue and
would be prejudiced by the requested relief.” (citing Park Cnty., 817 F.2d at 617));
Biodiversity’s Reply in Supp. of Mot. to Enforce, App. at 216 (“‘Laches must be invoked
sparingly in environmental cases be [sic, because] ordinarily the plaintiff will not be the
only victim of alleged environmental damage.’” (quoting Park Cnty., 817 F.2d at 617));
Order Den. Mot. to Enforce Settlement Agreement, App. at 251 (citing Park Cnty., 817
F.2d at 617; Jicarilla, 687 F.2d at 1338).



                                              - 89 -
here. Order Den. Mot. to Enforce Settlement Agreement, App. at 252. The district court

understood Biodiversity’s motion to enforce a breach of contract arises in a case about

environmental concerns but is different from a claim based on environmental statutes. It

decided the laches issue against that backdrop and was not persuaded this matter fits

squarely into the category of cases based on environmental statutes to which the doctrine

disfavoring laches typically applies.

       As a result, we are not persuaded the district court did not “consider the legal

standard disfavoring laches,” Park Cnty., 817 F.2d at 617, and therefore reject

Biodiversity’s abuse of discretion argument on this ground.73

2. Unreasonable Delay

       Biodiversity argues the district court erred in finding unreasonable delay by

(1) determining the delay in bringing the breach of Settlement Agreement claim began on

November 1, 2006—the date the Forest Chief denied Biodiversity’s administrative

challenge to the Phase II Amendment—and (2) concluding any delay was unreasonable.

See Aplt. Br. at 69-74.




       73
          We note the concern about applying laches to “defeat Congress’s environmental
policy,” Park Cnty., 817 F.2d at 617 (quotations omitted), is mitigated here because
(1) the motion to enforce was based on a contract—the Settlement Agreement—not a
federal statute embodying environmental policy, and (2) Biodiversity has had ample
opportunity to pursue its claims based on Congress’s environmental policy in its many
administrative challenges to the Phase II Amendment and its implementation, and
especially through its lawsuit in the Wyoming federal district court under NFMA, NEPA,
and the APA.



                                            - 90 -
       First, as to the beginning of delay, if the Phase II Amendment violates the

Settlement Agreement, Biodiversity knew or should have known of its breach claim at

least by November 1, 2006. Indeed, the record shows Biodiversity knew of its breach

claim even earlier when it filed its administrative challenge in May 2006, arguing “the

Phase II Amendment fails to live up to the USFS’s promises as set forth in the Settlement

Agreement.” Biodiversity’s Administrative Appeal, App. at 2683. Because contract

actions accrue at the moment of breach, see Zamora v. Prematic Serv. Corp., 936 F.2d

1121, 1123 (10th Cir. 1991) and Hersh Cos. Inc. v. Highline Vill. Assocs., 30 P.3d 221,

224 (Colo. 2001) (en banc),74 and because Biodiversity cannot argue it was unaware of its

breach claim, the district court did not clearly err or otherwise abuse its discretion in

using the November 1, 2006 date as the starting point for its laches analysis. See

Jacobsen v. Deseret Book Co., 287 F.3d 936, 949 (10th Cir. 2002) (“Generally speaking,

the relevant delay is the period from when the plaintiff knew (or should have known) of

the allegedly infringing conduct, until the initiation of the lawsuit in which the defendant

seeks to counterpoise the laches defense.”) (quotations omitted).

       Second, as to unreasonable delay, Biodiversity argues the district court ignored its

strategic and diligent pursuit of its rights by “rais[ing] violations of the 2000 settlement

agreement in its comments and administrative appeals.” Aplt. Br. at 71. Biodiversity

       74
          In contrast, APA challenges to forest plans for violating NFMA are not ripe
until they have been implemented through site-specific projects. Ohio Forestry Ass’n,
Inc. v. Sierra Club, 523 U.S. 726, 732-37 (1998). As such, Biodiversity’s arguments
regarding the “ripeness” of the breach claim under the principles in Ohio Forestry are
misplaced. See Aplt. Br. at 71-72.



                                             - 91 -
relies on Park County, 817 F.2d at 617-18, in which we concluded a district court erred in

holding that laches barred a NEPA claim. We reasoned that plaintiffs’ almost two-year

delay in bringing its NEPA challenge was not unreasonable or “sinister” because it was

merely a “tactical decision” to “concentrate their energies and resources” in “the most

efficient way to press their substantive objectives.” Id. at 618. Biodiversity argues its

almost seven-year delay is similarly not unreasonable because it made “strategic

decisions” to challenge the Phase II Amendment and the nine site-specific projects “in

administrative processes before resorting to litigation.” Aplt. Br. at 70-71.

       Park County is distinguishable on several grounds. First, the delayed claim in

Park County was a federal environmental statutory claim. Biodiversity’s claim is a

Settlement Agreement breach of contract claim. Second, the Park County plaintiffs

delayed less than two years before filing suit. Biodiversity delayed more than three times

longer to bring its motion. Third, the challenged project in Park County was

“not . . . substantially completed” because significant drilling activities “ha[d] not yet

transpired.” Park Cnty., 817 F.2d at 618. Biodiversity challenges a forest plan that the

Forest Service has substantially implemented in dozens of projects and has relied upon to

manage the BHNF for eight years. Fourth, we recognized the Park County plaintiffs’

efforts to streamline their litigation by focusing on challenging a drilling permit before

bringing the NEPA challenge. Id. By contrast, Biodiversity’s strategy increased

litigation. Starting in 2006, in numerous administrative challenges and then in the

Wyoming federal district court, Biodiversity alleged violations of the Settlement

Agreement even though, as the Wyoming court correctly decided, only the Colorado


                                             - 92 -
federal district court had jurisdiction to enforce the agreement. Order Den. Mot. for

Reconsideration, App. at 148-49.75 Biodiversity chose to avoid the Colorado federal

district court and attempted instead to enforce the Settlement Agreement in

administrative and district court forums lacking jurisdiction. Only after those efforts

failed did Biodiversity return to the Colorado federal district court, almost seven years

after its breach of contract claim accrued and nearly thirteen years after the Settlement

Agreement was finalized. Just because Biodiversity’s delay may have been strategic

does not make it reasonable—in fact, just the opposite.

       For the foregoing reasons, the district court did not abuse its discretion when it

determined that Biodiversity’s delay was unreasonable.

3. Undue Prejudice

       Biodiversity argues the district court abused its discretion by concluding the delay

prejudiced the Forest Service. It argues (1) the Forest Service was aware of

Biodiversity’s concerns, Aplt. Br. at 75, and (2) enforcement of the Settlement

Agreement would neither “halt any project underway” nor “necessarily delay ongoing




       75
          During that whole period, Biodiversity was aware the Colorado federal district
court had “retain[ed] jurisdiction of this matter for the purpose of entering such further
orders, direction, or relief as may be necessary or appropriate for the construction,
implementation, or enforcement of this Agreement . . . .” Settlement Agreement, App. at
442. As noted by the Wyoming federal district court, Biodiversity has “cited no authority
supporting the novel proposition that any federal district court other than the District of
Colorado could properly exercise ancillary jurisdiction to enforce the agreement.” Order
Den. Mot. for Reconsideration, App. at 148-49.



                                             - 93 -
on-the-ground implementation of projects.” Aplt. Reply Br. at 36; see also Aplt. Br. at

75-77.

         How much of the district court’s prejudice analysis rested on factual

determinations versus a balance of the equities is not clear. But whether we review the

district court’s determination of prejudice under clear error or abuse of discretion, we see

no reason to reverse the district court’s decision.

         First, no party disputes the Forest Service was aware of Biodiversity’s concerns.76

Starting in 2006, Biodiversity alleged Settlement Agreement violations in its

administrative challenges and in its Wyoming lawsuit. But that does not foreclose

prejudice to the Forest Service. The Forest Service devoted substantial time and

resources responding to Biodiversity’s various administrative challenges and its

Wyoming lawsuit while Biodiversity held in reserve the breach of contract claim it could

have brought at least by November 1, 2006. Based on Biodiversity’s jurisdictionally

defective protests of Settlement Agreement breach outside the Colorado forum, the Forest

Service may reasonably have been lulled into thinking Biodiversity had chosen the route

of challenging the Phase II Amendment for violations of NFMA and NEPA under the

APA in lieu of attempting to enforce the Settlement Agreement in Colorado. See Pro

         76
         On this score, we disagree with the district court’s statement that there was “no
apparent indication that plaintiffs believed such implementation [of the Phase II
Amendment] to constitute a violation of the Settlement Agreement.” Order Den. Mot. to
Enforce the Settlement Agreement, App. at 253. That the Forest Service was on notice of
Biodiversity’s Settlement Agreement violation concerns, however, not only does not alter
our unreasonable delay and undue prejudice analysis, it strengthens it given the
circumstances of this case.



                                              - 94 -
Football, Inc. v. Harjo, 565 F.3d 880, 884 (D.C. Cir. 2009) (“When there has been an

unreasonable period of delay by a plaintiff . . . prejudice to the defendant may ensue

whether or not the plaintiff overtly lulled the defendant into believing that the plaintiff

would not act, or whether or not the defendant believed that the plaintiff would have

grounds for action.”).

       Second, Biodiversity’s argument that enforcing the Settlement Agreement would

not “necessarily delay” ongoing projects, Aplt. Reply Br. at 36, overlooks the prejudice

the Forest Service would suffer from Biodiversity’s delayed motion. As the district court

noted, “the Forest Service has managed the BHNF in accordance with the Phase II

[A]mendment” as a blueprint for nearly eight years, including implementing dozens of

projects and creating a forest-wide strategy to combat insect infestation and fire risks.

Order Den. Mot. to Enforce Settlement Agreement, App. at 253. During the period of

delay since November 2006, the Forest Service has invested significant time and

resources, and requiring the Forest Service to change its blueprint governing these efforts

would compromise work that has already been done.

       For example, the district court observed the Forest Service “proffered evidence

substantiating that [it] has undertaken significant efforts to manage the mountain pine

beetle infestation that has plagued the BHNF in reliance on the Phase II [A]mendment

and the terms of the Settlement Agreement.” Order Den. Mot. to Enforce Settlement

Agreement, App. at 253. Because the BHNF includes within its boundaries not only

federally managed lands, but also parcels of state-managed and private lands, the Forest

Service has worked with the Intervenors and private landowners to battle the bark beetle


                                             - 95 -
epidemic using a “wall to wall” coordinated strategy. See Am. Decl. of S.D. State

Forester Raymond Sowers, App. at 209. Requiring the Forest Service to revisit and

revise the Phase II Amendment now would threaten what has been achieved so far: “a

comprehensive and continual program is required,” and an interruption “in implementing

the measures already underway poses a significant risk not only to the forest itself, but to

property and persons located adjacent to it.” Order Den. Mot. to Enforce Settlement

Agreement, App. at 253; see also Intervenors’ Opp’n to Mot. to Enforce, App. at 185

(“This is not the time to stop for more study and then start again. Laches applies because

. . . [the parties] have relied on the current Phase II and associated projects to invest

heavily in control of the mountain pine beetle, and the beetle control efforts must be

continued to be effective.”).

       The district court properly weighed “the peculiar equitable circumstances” in this

case, Czaplicki, 351 U.S. at 533, and determined the Forest Service would be unduly

prejudiced from the delay in Biodiversity’s requested relief. We discern no reason to

conclude the district court abused its discretion.

                                    IV. CONCLUSION

       In Case No. 13-8053, we affirm the Wyoming federal district court’s denial of

Biodiversity’s petition for review under the APA. In Case No. 13-1352, we affirm the

Colorado federal district court’s dismissal of Biodiversity’s motion to enforce the

Settlement Agreement.
