Appeal from the United States District Court
for the District of Montana
Donald W. Molloy, District Judge, Presiding
Argued and Submitted February 6, 2025
Portland, Oregon
Before: BEA, KOH, and SUNG, Circuit Judges.
3
This appeal involves consolidated cases concerning the Black Ram Project
(“Project”) in the Kootenai National Forest and its effects on the grizzly bear.
Plaintiffs Center for Biological Diversity, Yaak Valley Forest Council, and
WildEarth Guardians (collectively, “CBD”) along with consolidated plaintiffs
Alliance for the Wild Rockies and Native Ecosystems Council (collectively,
“AWR”) brought suit against the United States Forest Service (the “Forest
Service”) and the United States Fish and Wildlife Service (“FWS”) (collectively,
“federal defendants”), alleging that approval of the Project violated the Endangered
Species Act (“ESA”), the National Environmental Policy Act (“NEPA”), and the
National Forest Management Act (“NFMA”). The Kootenai Tribe of Idaho (the
“Tribe”) intervened as a defendant.
On cross motions for summary judgment, the district court ruled for CBD on
four claims, for AWR on three claims, and for the defendants on five claims. The
federal defendants appeal the district court’s grant of summary judgment to CBD
on CBD’s claims 4 and 7 and the district court’s grant of summary judgment to
AWR on AWR’s claims 1 and 3. The Tribe joins the federal defendants’ appeal
and additionally appeals the district court’s grant of summary judgment to CBD on
CBD’s claim 1. On cross appeal, CBD challenges the district court’s grant of
summary judgment to the federal defendants on CBD’s claim 6.
We review the district court’s summary judgment decision de novo.

Corrigan v. Haaland, 12 F.4th 901, 906 (9th Cir. 2021). Our review of agency
decision-making under the ESA, NEPA, and NFMA is governed by the judicial
review provisions of the Administrative Procedure Act (“APA”), 5 U.S.C. § 706.
See Friends of the Inyo v. U.S. Forest Serv., 103 F.4th 543, 551 (9th Cir. 2024)
(NEPA claims); San Luis & Delta-Mendota Water Auth. v. Jewell, 747 F.3d 581,
601 (9th Cir. 2014) (ESA and NEPA claims); Native Ecosystems Council v. U.S.
Forest Serv., 418 F.3d 953, 960 (9th Cir. 2005) (NFMA claims). Under the APA, a
reviewing court may set aside agency action only if it is “arbitrary, capricious, an
abuse of discretion, or otherwise not in accordance with law.” 5 U.S.C.
§ 706(2)(A).
1. As an initial matter, AWR argues that the federal defendants lack
Article III standing because they appeal some, but not all, of the district court’s
adverse rulings and do not appeal the vacatur of the underlying project decision.
This argument is squarely foreclosed by our precedents. See All. for Wild Rockies
v. Petrick, 68 F.4th 475, 486-87 (9th Cir. 2023) (holding that the Forest Service
had standing where it “challenge[d] what the district court ordered it to do on
remand”); Crow Indian Tribe v. United States, 965 F.3d 662, 675-76 (9th Cir.
2020) (“FWS has standing[] because its alleged injury—being required to
reevaluate certain aspects of [a challenged rule] that it claims are legal—is
redressable by a favorable decision.”). The district court ordered the federal
5
defendants to remedy multiple discrete statutory violations. “Because the manner
in which the [federal defendants] would reevaluate [the Project] on remand would
be altered by a favorable decision by this court,” their injury is redressable, and the
federal defendants have standing. Crow Indian Tribe, 965 F.3d at 676.
2. We reverse the district court’s grant of summary judgment to CBD on
CBD’s claim 4 and hold that the grizzly bear population estimate in the FWS
biological opinion’s environmental baseline satisfies the ESA’s best available data
requirement. See 16 U.S.C. § 1536(a)(2) (stating that agencies “shall use the best
scientific and commercial data available”).
In its biological opinion, FWS relied on a peer-reviewed study that used a
well-established statistical method to estimate the baseline population of grizzly
bears. FWS’s reasonable determination that this study was the best available data is
entitled to deference. See San Luis & Delta-Mendota Water Auth., 747 F.3d at 602
(“The determination of what constitutes the ‘best scientific data available’ belongs
to the agency’s ‘special expertise.’” (first quoting 16 U.S.C. § 1536(a)(2); then
quoting Baltimore Gas & Elec. Co. v. Nat. Res. Def. Council, Inc., 462 U.S. 87,
103 (1983))).
The district court nonetheless concluded that FWS had violated the best
available data requirement because it “disregarded biological information
indicating an increase in grizzly bear mortality” and “ignore[d] the issue of female
6
bear mortality altogether.” Ctr. for Biological Diversity v. U.S. Forest Serv., 687 F.
Supp. 3d 1053, 1068-69 (D. Mont. 2023) [hereinafter “MSJ Opinion”].
Specifically, the district court faulted FWS for failing to consider documented bear
mortalities and failing to adequately credit annual minimum count data that
showed a decline in the number of bears detected between 2017 and 2020. See id.
However, the study that FWS relied on for its grizzly bear population estimate
directly incorporated bear mortality—both reported and unreported—into its
population modeling. Moreover, FWS explicitly considered the annual minimum
count data, but reasonably explained that this methodology over-simplified
population biology. See San Luis & Delta-Mendota Water Auth. v. Locke, 776 F.3d
971, 995 (9th Cir. 2014) (“An agency complies with the best available science
standard so long as it does not ignore available studies, even if it disagrees with or
discredits them.”).
Because FWS relied on a sound statistical method and considered all
relevant factors in establishing the environmental baseline for grizzly bears in its
biological opinion, the district court erred in holding that FWS violated the ESA’s
best available data requirement.
3. We reverse the district court’s grant of summary judgment to CBD on
CBD’s claim 7. An agency violates the ESA if it relies on a legally flawed
biological opinion. See Ctr. for Biological Diversity v. U.S. Bureau of Land Mgmt.,
7
698 F.3d 1101, 1127-28 (9th Cir. 2012). Here, the district court determined that
FWS’s biological opinion was flawed only because it “failed to use the best
available science to create its environmental baseline for grizzly bears.” MSJ
Opinion, 687 F. Supp. 3d at 1072. As discussed above, this conclusion was error.
Therefore, it was not arbitrary and capricious for the Forest Service to approve of
the Project pursuant to the biological opinion.
4. We reverse the district court’s grant of summary judgment to CBD on
CBD’s claim 1. Although it was error under NEPA for the Forest Service to rely
on stale grizzly bear population data in establishing the environmental baseline in
its final environmental assessment, this error was harmless. See 5 U.S.C. § 706
(reviewing courts shall take “due account . . . of the rule of prejudicial error”).
“The harmless-error analysis asks whether the failure to consult materially
impeded NEPA’s goals—that is, whether the error caused the agency not to be
fully aware of the environmental consequences of the proposed action, thereby
precluding informed decision[-]making and public participation, or otherwise
materially affected the substance of the agency’s decision.” Idaho Wool Growers
Ass’n v. Vilsack, 816 F.3d 1095, 1104 (9th Cir. 2016).
Here, CBD has failed to identify how the Forest Service’s citation to the
stale data materially affected the agency’s decision or public participation. In its
final environmental assessment, which was issued in June 2022, the Forest Service
8
cited a study estimating the grizzly bear population as of 2017. The grizzly bear
population data that became available between 2017 and 2022, however, did not
reflect a meaningfully different condition for the grizzly bear. Indeed, updated data
reflected potential improvement in the grizzly bear’s condition. The 2017
population estimate was 55 to 60 bears, whereas the 2021 population estimate was
60 to 65 bears. Considering these facts, newer data would not have altered the
Forest Service’s analysis or decision, and CBD has failed to articulate any way in
which public participation could have been materially affected. See Idaho Wool
Growers, 816 F.3d at 1104.
5. We affirm the district court’s grant of summary judgment to AWR on
AWR’s claim 1 and hold that the Forest Service failed to demonstrate compliance
with Standard FW-STD-WL-02 of the Access Amendments (“Access Standard 2”)
in the 2015 Kootenai National Forest Plan in violation of NFMA. See Native
Ecosystems Council, 418 F.3d at 961 (“Under NFMA . . . we must still be able
reasonably to ascertain from the record that the Forest Service is in compliance
with [the forest plan’s standards].”). Specifically, because the extent to which the
Forest Service included unauthorized road use in its core habitat and road density
calculations is unclear, it is impossible to discern from the record whether the
Project has complied with Access Standard 2.
The Access Amendments do not differentiate between authorized and
9
unauthorized road use, nor does a plain reading of the relevant definitions for road
density metrics suggest that unauthorized road use can be excluded from core
habitat and road density calculations. Rather, the Access Amendments’ road
density definitions explicitly contemplate the effectiveness of road closures and
actual functionality of roads. Therefore, the Forest Service may not exclude
categorically documented unauthorized road use. See All. for Wild Rockies v.
Bradford, 856 F.3d 1238, 1243 (9th Cir. 2017) (explaining that “any closure that
fails to effectively prevent motorized access also fails to comply with [Access
Standard 2]”).
The federal defendants argue that unauthorized road use need not have been
counted because Access Standard 2 limits only permanent road mileage. The
federal defendants assert that the Forest Service “promptly” fixes unauthorized
road use issues and that “unauthorized use on any given route is not chronic from
year to year.” Although the federal defendants correctly argue that Access
Standard 2 places restrictions only on permanent routes, the record belies the
federal defendants’ blanket assertion that unauthorized road use is sporadic and
temporary. Rather, the record shows that unauthorized road use was observed in
the Project’s action area during three of eight monitored years and that only a small
fraction of gate and barrier breaches are promptly repaired. Given the uncertainty
as to the extent of ineffective closures and chronic unauthorized road use, it is
10
impossible to discern actual, baseline motorized access conditions. Therefore, in
violation of NFMA, it is also impossible to discern whether the Project complies
with Access Standard 2. See All. for Wild Rockies v. Savage, 897 F.3d 1025, 1035
(9th Cir. 2018) (“[T]he Forest Service’s ‘failure to measure [linear road miles] as
defined by the [Access Amendments] renders us unable to determine from the
record that the agency is complying with the forest plan standard.’” (second and
third alterations in original) (quoting Hapner v. Tidwell, 621 F.3d 1239, 1250 (9th
Cir. 2010))).
Of note, the district court also determined that the Forest Service obscured
its methodology for how compliance with Access Standard 2 was calculated in
violation of NEPA. See MSJ Order, 687 F. Supp. 3d at 1082. NEPA requires
agencies to “identify any methodologies used” and “make explicit reference by
footnote to the scientific and other sources relied upon for conclusions in the
statement.” 40 C.F.R. § 1502.24 (2018).1 We do not agree that the Forest Service
failed to comply with this specific procedural regulation in its final environmental
assessment. The Forest Service identified the metrics it used to measure changes to
core grizzly bear habitat and road densities and identified the source of these
1
NEPA’s implementing regulations were updated in 2020. See Update to the
Regulations Implementing the Procedural Provisions of the National
Environmental Policy Act, 85 Fed. Reg. 43,304 (July 16, 2020). As the agencies
applied the previous regulations to the Project, so do we. See Bair v. Cal. Dep’t of
Transp., 982 F.3d 569, 577 n.20 (9th Cir. 2020).
11
metrics as the Access Amendments. It further explained that these metrics would
be calculated using geographic information system (GIS) applications. This
satisfies the methodological requirements of § 1502.24. We decline to require that
the Forest Service explain its methodology with more specificity than the
implementing regulation requires. See Earth Island Inst. v. Carlton, 626 F.3d 462,
472 (9th Cir. 2010) (“Courts may not impose procedural requirements not
explicitly enumerated in the pertinent statutes.” (internal quotation marks and
citation omitted)).
Nonetheless, because the Forest Service failed to demonstrate substantive
compliance with Access Standard 2 in violation of NFMA, we affirm the district
court’s grant of summary judgment to AWR on AWR’s claim 1.
6. We affirm the district court’s grant of summary judgment to AWR on
AWR’s claim 3 and hold that the Forest Service failed to take a “hard look” at
unauthorized road use in violation of NEPA. Under NEPA, an agency’s
“assessment of baseline conditions ‘must be based on accurate information and
defensible reasoning.’” Great Basin Res. Watch v. Bureau of Land Mgmt., 844
F.3d 1095, 1101 (9th Cir. 2016) (quoting Oregon Nat. Desert Ass’n v. Jewell, 840
F.3d 562, 570 (9th Cir. 2016)); see also Native Ecosystems Council, 418 F.3d at
964 (“To take the required ‘hard look’ at a proposed project’s effects . . . an agency
may not rely on incorrect assumptions or data.”).
12
As discussed above, the Forest Service’s analysis of baseline conditions and
the Project’s compliance with Access Standard 2 was premised on unsupported
assumptions that unauthorized roads use is sporadic and temporary, and that
ineffective barriers and road closures would be promptly repaired. The Forest
Service’s “failure to explain [these] baseline assumption[s] frustrated [its] ability to
take a ‘hard look’” at the effects of unauthorized road use. Great Basin Res.
Watch., 844 F.3d at 1104.
7. On cross appeal, we affirm the district court’s grant of summary
judgment to the federal defendants on CBD’s claim 6 and hold that FWS’s no
jeopardy determination was not arbitrary and capricious. FWS evaluated all
relevant factors and reasonably concluded that the Project was not likely to
jeopardize the existence of the species as a whole. See 16 U.S.C. § 1536(a)(2); 50
C.F.R. § 402.14(g)(4), (h)(1)(iv); see also 50 C.F.R. § 402.02 (“Jeopardize the
continued existence of means to engage in an action that reasonably would be
expected, directly or indirectly, to reduce appreciably the likelihood of both the
survival and recovery of a listed species in the wild by reducing the reproduction,
numbers or distribution of that species.”).
FWS concluded that the Project could have adverse effects on a few
individual female grizzly bears but explained that these effects were “expected to
be non-lethal” and could “decrease[] reproduction for 1-2 reproductive cycles.”
13
FWS’s conclusion that a temporary reduction in reproduction for a few individual
bears would not jeopardize the species as a whole was reasonable. See Rock Creek
All. v. U.S. Fish & Wildlife Serv., 663 F.3d 439, 443 (9th Cir. 2011) (upholding a
no jeopardy determination for the bull trout even where FWS concluded “the rate
of recovery of the core area population may slow slightly”).
