Endangered and Threatened Wildlife and Plants; Finding for the 
Gray Wolf in the Northern Rocky Mountains and the Western United States

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notification of finding.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a 
finding on the gray wolf (Canis lupus) in the Northern Rocky Mountains 
(NRM) and in the Western United States. After a thorough review of the 
best available scientific and commercial data, we find that gray wolves 
within the NRM area do not, on their own, represent a valid listable 
entity; therefore, the NRM is not warranted for listing under the 
Endangered Species Act of 1973, as amended (Act). We find that the gray 
wolf in the Western United States is a valid listable entity; however, 
the gray wolf in the Western United States does not meet the definition 
of an endangered species or a threatened species. Thus, we find that 
listing the gray wolf in the Western United States is not warranted at 
this time.

DATES: The finding in this document was made on February 7, 2024.

ADDRESSES: This finding and the supporting information that we 
developed for this finding, including the species status assessment 
(SSA) report and species assessment form, are available on the internet 
at https://www.regulations.gov at Docket No. FWS-HQ-ES-2021-0106. 
Please submit any new information, materials, comments, or questions 
concerning this finding to the appropriate person, as specified under 
FOR FURTHER INFORMATION CONTACT.

SUPPLEMENTARY INFORMATION:

Previous Federal Actions

    Gray wolves were originally listed as subspecies or as regional 
populations of subspecies in the lower 48 United States and Mexico. We 
detail these various original rulemakings in the November 3, 2020, rule 
delisting the gray wolf throughout much of its range in the lower 48 
States and Mexico (85 FR 69778).
    In 1978, we published a rule reclassifying the gray wolf in 
Minnesota as a threatened species and gray wolves elsewhere in the 
lower 48 United States and Mexico as an endangered species. We later 
revised this listing by designating the population of gray wolves in 
the NRM, including Idaho, Montana, and Wyoming, the eastern one-third 
of Oregon and Washington, and a small portion of north-central Utah, as 
a Distinct Population Segment (DPS) and, following legal challenges and 
several rulemakings, ultimately delisting this population due to 
recovery (74 FR 15123, April 2, 2009; 76 FR 25590, May 5, 2011; 77 FR 
55530, September 10, 2012; 82 FR 20284, May 1, 2017). Since delisting, 
gray wolves in the NRM have been managed by the States and Tribes.
    On November 3, 2020, we published a final rule removing the Act's 
protections for gray wolves everywhere they were listed in the lower 48 
States and Mexico, not including the Mexican

[[Page 8392]]

wolf subspecies (Canis lupus baileyi) (85 FR 69778). The rule took 
effect January 4, 2021.
    On June 1, 2021, we received a petition from the Center for 
Biological Diversity, the Humane Society of the United States, Humane 
Society Legislative Fund, and the Sierra Club requesting that the gray 
wolf in the NRM be emergency listed as a threatened species or an 
endangered species under the Act. The petition included, as an 
alternative option, a request that we list a Western DPS of gray wolf 
that would include all of California, Colorado, Idaho, Montana, Nevada, 
Oregon, Utah, Washington, and Wyoming, and, if the Service chose to 
include them, Arizona and New Mexico, north of Interstate 40 (first 
petition). The Act does not provide a process to petition for emergency 
listing; therefore, we evaluated this petition under the normal process 
of determining if it presented substantial scientific or commercial 
information indicating that the petitioned action may be warranted.
    On July 29, 2021, we received a petition from Western Watersheds 
Project and 70 other organizations requesting that gray wolves in 
Idaho, Montana, Wyoming, Utah, Oregon, Washington, Colorado, 
California, Nevada, and northern Arizona be listed as an endangered 
species under the Act (second petition). On August 10, 2021, we 
received an addendum to the second petition, which provided minor 
clarifications and corrections to the original petition but did not 
change the scope of the petitioned entity.
    On September 17, 2021, we published a 90-day finding (86 FR 51857) 
concluding that both petitions contained substantial information 
indicating that the petitioned actions may be warranted, and we 
initiated a status review to determine whether the petitioned actions 
were warranted.
    On February 10, 2022, the gray wolf 2020 final delisting rule was 
vacated and remanded by the U.S. District Court for the Northern 
District of California. (Defenders of Wildlife v. US Fish and Wildlife 
Service, No. 21-00344 (N.D. Cal.), WildEarth Guardians v. Bernhardt, 
No. 21-00349 (N.D. Cal.), NRDC v. U.S. Department of the Interior, No. 
21-00561 (N.D. Cal.)). On November 3, 2023, we published a final rule 
to comply with the district court's order (88 FR 75506). As a result, 
all gray wolves in the lower 48 States, outside of the NRM, are 
currently listed under the Act. The court's decision was specific to 
the gray wolf and does not affect the separate endangered listing of 
the Mexican wolf subspecies.
    On March 1, 2022, we received a petition from the International 
Wildlife Coexistence Network and nine other organizations requesting 
that a DPS of the gray wolf in the NRM or in the Western United States 
be emergency listed under the Act. As stated previously, we evaluate 
petitions requesting emergency listing under our normal petition review 
process. However, because we were actively engaged in a status review 
of the entities for which the petitioners requested listing, we did not 
issue a 90-day finding; rather, we evaluated the information provided 
by the petitioners in the context of this status review.
    On August 9, 2022, petitioners (June 1, 2021 petition) filed a 
lawsuit to compel us to complete a 12-month finding on their petition 
(Center for Biological Diversity et al. v. U.S. Department of the 
Interior et al. No. 22-00134 (D. MT). On March 31, 2023, the parties 
entered into a settlement agreement under which the Service agreed 
that, on or before February 2, 2024, we would submit to the Federal 
Register a determination as to whether listing a Northern Rocky 
Mountains DPS or a Western United States DPS of the gray wolf as a 
threatened species or an endangered species is warranted, not 
warranted, or warranted but precluded by other pending proposals.

Background

    Under section 4(b)(3)(B) of the Act (16 U.S.C. 1531 et seq.), we 
are required to make a finding, within 12 months after receiving any 
petition that we have determined contains substantial scientific or 
commercial information indicating that the petitioned action may be 
warranted, as to whether the petitioned action is warranted, not 
warranted, or warranted but precluded by other pending proposals (known 
as a ``12-month finding''). We must publish a notification of this 12-
month finding in the Federal Register.

Listable Entity Requirements

    Under the Act, the term ``species'' includes any subspecies of fish 
or wildlife or plants, and any distinct population segment of any 
vertebrate fish or wildlife which interbreeds when mature (16 U.S.C. 
1532(16)). To interpret and implement the distinct population segment 
(DPS) provisions of the Act, the Service and the National Oceanic and 
Atmospheric Administration published in the Federal Register the Policy 
Regarding the Recognition of Distinct Vertebrate Population Segments 
Under the Endangered Species Act on February 7, 1996 (61 FR 4722) (DPS 
Policy). Under the DPS Policy, we consider three elements to determine 
whether to classify a population of a vertebrate species as a DPS: (1) 
the discreteness of the population segment in relation to the remainder 
of the species to which it belongs; (2) the significance of the 
population segment to the species to which it belongs; and (3) the 
population segment's conservation status in relation to the Act's 
standard for listing, delisting, or reclassification. Both discreteness 
and significance are used to determine whether the population segment 
constitutes a valid DPS. If it does, then the population segment's 
conservation status is used to consider whether the DPS warrants 
listing.

Summary of Biological Information

    Gray wolves are the largest wild members of the Canidae or dog 
family (Mech 1974, pp. 11-12). Gray wolves have a circumpolar range 
including North America, Europe, and Asia. In the Western United 
States, the gray wolf currently occurs in one interconnected 
metapopulation with packs distributed across California, Idaho, 
Montana, Oregon, Washington, and Wyoming, and, more recently, wolves 
have been documented in Colorado (Service 2023, pp. 13-16).
    Gray wolves are highly territorial, social animals and group 
hunters, normally living in packs with high reproductive capacity (Mech 
1970, pp. 38-43; Mech and Boitani 2003, p. 8; Paquet and Carbyn 2003, 
pp. 485-486; Stahler et al. 2020, p. 46). Gray wolves are habitat 
generalists, meaning they can thrive in a variety of habitats and 
consume a diversity of prey species (though wolves are primarily 
predators of medium and large mammals) (Mech and Boitani 2003, p. 163). 
In general, to maintain populations in the wild over time, wolves in 
the Western United States need well-connected and genetically diverse 
subpopulations that function as a metapopulation distributed across 
enough of their range to be able to withstand stochastic events, 
rebound after catastrophes (e.g., severe disease outbreaks), and adapt 
to changing environmental conditions (Service 2023, p. 29).

Summary of Information Pertaining to the Five Factors

    Section 4 of the Act (16 U.S.C. 1533) and the implementing 
regulations at part 424 of title 50 of the Code of Federal Regulations 
(50 CFR part 424) set forth procedures for adding species to, removing 
species from, or reclassifying species on the Lists of Endangered and 
Threatened Wildlife and Plants (Lists). The Act defines

[[Page 8393]]

``species'' as including any subspecies of fish or wildlife or plants, 
and any distinct population segment of any species of vertebrate fish 
or wildlife which interbreeds when mature (16 U.S.C. 1532(16)). The Act 
defines an ``endangered species'' as any species that is in danger of 
extinction throughout all or a significant portion of its range (16 
U.S.C. 1532(6)), and a ``threatened species'' as any species that is 
likely to become an endangered species within the foreseeable future 
throughout all or a significant portion of its range (16 U.S.C. 
1532(20)). Under section 4(a)(1) of the Act, a species may be 
determined to be an endangered species or a threatened species because 
of any of the following five factors:
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;
    (B) Overutilization for commercial, recreational, scientific, or 
educational purposes;
    (C) Disease or predation;
    (D) The inadequacy of existing regulatory mechanisms; or
    (E) Other natural or manmade factors affecting its continued 
existence.
    These factors represent broad categories of natural or human-caused 
actions or conditions that could have an effect on a species' continued 
existence. In evaluating these actions and conditions, we look for 
those that may have a negative effect on individuals of the species, as 
well as other actions or conditions that may ameliorate any negative 
effects or may have positive effects.
    We use the term ``threat'' to refer in general to actions or 
conditions that are known to or are reasonably likely to negatively 
affect individuals of a species. The term ``threat'' includes actions 
or conditions that have a direct impact on individuals (direct 
impacts), as well as those that affect individuals through alteration 
of their habitat or required resources (stressors). The term ``threat'' 
may encompass--either together or separately--the source of the action 
or condition or the action or condition itself.
    However, the mere identification of any threat(s) does not 
necessarily mean that the species meets the statutory definition of an 
``endangered species'' or a ``threatened species.'' In determining 
whether a species meets either definition, we must evaluate all 
identified threats by considering the expected response by the species, 
and the effects of the threats--in light of those actions and 
conditions that will ameliorate the threats--on an individual, 
population, and species level. We evaluate each threat and its expected 
effects on the species, then analyze the cumulative effect of all of 
the threats on the species as a whole. We also consider the cumulative 
effect of the threats in light of those actions and conditions that 
will have positive effects on the species, such as any existing 
regulatory mechanisms or conservation efforts. The Secretary determines 
whether the species meets the Act's definition of an ``endangered 
species'' or a ``threatened species'' only after conducting this 
cumulative analysis and describing the expected effect on the species 
now and in the foreseeable future.
    The Act does not define the term ``foreseeable future,'' which 
appears in the statutory definition of ``threatened species.'' Our 
implementing regulations at 50 CFR 424.11(d) set forth a framework for 
evaluating the foreseeable future on a case-by-case basis. The term 
``foreseeable future'' extends only so far into the future as we can 
reasonably determine that both the future threats and the species' 
responses to those threats are likely. In other words, the foreseeable 
future is the period of time in which we can make reliable predictions. 
``Reliable'' does not mean ``certain''; it means sufficient to provide 
a reasonable degree of confidence in the prediction. Thus, a prediction 
is reliable if it is reasonable to depend on it when making decisions.
    It is not always possible or necessary to define the foreseeable 
future as a particular number of years. Analysis of the foreseeable 
future uses the best scientific and commercial data available and 
should consider the timeframes applicable to the relevant threats and 
to the species' likely responses to those threats in view of its life-
history characteristics. Data that are typically relevant to assessing 
the species' biological response include species-specific factors such 
as lifespan, reproductive rates or productivity, certain behaviors, and 
other demographic factors.
    In conducting our evaluation of the five factors in section 4(a)(1) 
of the Act to determine whether the gray wolf in the Western United 
States meets the Act's definition of an ``endangered species'' or 
``threatened species,'' we considered and thoroughly evaluated the best 
scientific and commercial information available regarding the past, 
present, and future stressors and threats. We reviewed the petitions, 
information available in our files, and other available published and 
unpublished information for the gray wolf in the Western United States. 
Our evaluation included information from recognized experts; Federal, 
State, and Tribal governments; academic institutions; foreign 
governments; private entities; and other members of the public.
    This document announces the not-warranted finding for the gray wolf 
in the NRM and the gray wolf in the Western United States, in 
accordance with the regulations at 50 CFR 424.14(h)(2)(i). In this 
document, we have also elected to include a summary of the analysis on 
which this finding is based. We provide the full analysis, including 
our rationale and the data on which the finding is based, in the 
decisional file for the action in this document. The following is a 
description of the documents containing this full analysis:
    The species assessment form contains detailed biological 
information; a thorough analysis of the listing factors; an explanation 
of why we determined (1) the gray wolf in the NRM is not a valid 
listable entity and (2) the gray wolf in the Western United States is a 
valid listable entity, but this entity does not meet the Act's 
definition of an ``endangered species'' or a ``threatened species''; 
and a list of literature cited. To inform our status review, we 
completed an SSA Report for the gray wolf in the Western United States 
(Service 2023, entire). The SSA contains a thorough review of the 
taxonomy, life history, ecology, current condition, and projected 
future condition for the gray wolf in the Western United States. This 
supporting information can be found on the internet at https://www.regulations.gov at Docket No. FWS-HQ-ES-2021-0106 (see ADDRESSES, 
above).
    Our analysis for this decision applied our current regulations, 
portions of which were last revised in 2019. Given that we proposed 
further revisions to these regulations on June 22, 2023 (88 FR 40764), 
we have also analyzed whether the decision would be different if we 
were to apply those proposed revisions. We concluded that the decision 
would have been the same if we had applied the proposed 2023 
regulations. The analysis under both the regulations currently in 
effect and the regulations after incorporating the June 22, 2023, 
proposed revisions are included in our decision file for this action.

Gray Wolf in the NRM

Summary of Finding
    After a thorough review of the best available scientific and 
commercial data, we determined that gray wolves within the boundaries 
of the NRM DPS described in our 2009 rule (i.e., Idaho, Montana, and 
Wyoming, the eastern

[[Page 8394]]

one-third of Oregon and Washington, and a small portion of north-
central Utah) no longer constitute a valid DPS. Gray wolves in the NRM 
are not markedly separated from other populations of the taxon outside 
of the NRM western boundary (i.e., the wolves in the eastern one-third 
of Oregon and Washington are not markedly separated from the wolves in 
California and the western two-thirds of Oregon and Washington) and, 
therefore, the NRM does not meet the ``discreteness'' element of the 
DPS Policy as a consequence of physical, physiological, ecological, or 
behavioral factors (61 FR 4722, February 7, 1996). Thus, we find that 
gray wolves in the NRM area do not, on their own, represent a valid DPS 
and we do not consider the status of gray wolves in the NRM area as a 
separately listable entity. However, we considered the status of gray 
wolves in the NRM area in the context of our significant portion of the 
range analysis for the gray wolf in the Western United States (see 
below). A detailed discussion of the basis for this finding can be 
found in the species assessment form and other supporting documents 
(see ADDRESSES, above).

Gray Wolf in the Western United States

Summary of Finding
    Based on our review of the best available scientific data, we 
determined that the gray wolf in the Western United States is a DPS. We 
find that the gray wolf in the Western United States meets both 
possible discreteness criteria of our DPS Policy: (1) it is markedly 
separated, genetically and physically, from other populations of the 
taxon (i.e., wolves in the Great Lakes area and ``coastal wolves''); 
and (2) it is delimited by international governmental boundaries (the 
United States and Canada border) within which differences in control of 
exploitation and regulatory mechanisms exist that are significant in 
light of section 4(a)(1)(D) of the Act (61 FR 4722, February 7, 1996). 
We also find that the gray wolf in the Western United States meets the 
significance criteria of the DPS Policy because its loss would result 
in a significant gap in the range of the taxon because it would create 
a gap of more than 1,000 mi (1,600 km) between the Mexican wolf 
subspecies of gray wolf to the south of the Western United States wolf 
metapopulation and gray wolves in Canada to the north. Because the 
Western United States population of gray wolf is both discrete and 
significant, we determined that it is a valid DPS and considered its 
conservation status under the Act.
    We have carefully assessed the best scientific and commercial 
information available regarding the past, present, and future threats 
to the gray wolf in the Western United States and evaluated the five 
listing factors, including any regulatory mechanisms and conservation 
measures addressing these threats. The primary stressors with the 
potential to affect the gray wolf's biological status include human-
caused mortality (Factor C), disease and parasites (Factor C), and 
inbreeding depression (Factor E) (Service 2023, pp. 30-93). We also 
considered the potential effects of climate change (Factor E), diseases 
in prey species (Factor E), and other sources of habitat modification 
(Factor A) on gray wolves in the Western United States, but these 
stressors have not negatively influenced gray wolf viability, nor are 
they anticipated to do so in the foreseeable future (Service 2023, pp. 
93-103).
    Our assessment of current condition indicates that habitat and prey 
for wolves are abundant and well distributed in the Western United 
States. This, in conjunction with the high reproductive potential of 
wolves and their innate behavior to disperse and locate social openings 
or vacant suitable habitats, has allowed wolf populations to withstand 
relatively high rates of human-caused mortality. Our analysis of the 
current condition of gray wolves in the Western United States 
demonstrates that, despite current levels of regulated harvest, lethal 
control, and episodic disease outbreaks, wolf abundance in the Western 
United States has generally continued to increase and occupied range 
has continued to expand since reintroduction in the 1990s, with the 
exception of 3 years during which wolf abundance in the Western 
metapopulation decreased slightly (i.e., a decrease of approximately 50 
to 100 wolves in 1 year). As of the end of 2022, States estimated that 
there were 2,797 wolves distributed among at least 286 packs in 7 
States. This large population size and broad distribution contributes 
to the resiliency and redundancy of wolves in the Western United 
States. Moreover, wolves in the Western United States currently have 
high levels of genetic diversity and connectivity, further supporting 
the resiliency of wolves throughout the West. Finally, based on several 
metrics for assessing adaptive capacity, wolves in the Western United 
States currently retain the ability to adapt to changes in their 
environment (representation) (Service 2023, pp. 104-134).
    We also evaluated the future condition of gray wolves in the 
Western United States under multiple different future scenarios that 
varied levels of harvest and disease. Our analysis indicates that 
wolves will avoid extirpation in the Western United States over the 
next 100 years. Even in the extremely unlikely scenarios in which 
harvest substantially increases and is maintained at high rates over 
time in Idaho and Montana, while population sizes decrease in these 
states, the overall population remains well above quasi-extinction 
levels in the Western United States; the median projected population 
sizes for the entirety of Idaho, Montana, Oregon, Washington, and 
Wyoming (the five states we modeled) in 100 years ranged from 935 
wolves (95% Credible Interval 739-1,091) for the most impactful 
combination of disease and harvest scenarios we analyzed to 2,161 
wolves (95% Credible Interval 1,684-2,586) for the least impactful 
combination of disease and harvest scenarios we analyzed. More 
generally, gray wolves in the Western metapopulation will retain the 
ability to withstand stochastic and catastrophic events in the future 
(resiliency and redundancy) despite the decrease in the number of 
wolves relative to current condition under our future scenarios. We 
also expect the population size to remain large enough, with sufficient 
connectivity and genetic diversity, to avoid consequential levels of 
inbreeding or inbreeding depression in the future. Given this 
maintained connectivity, combined with wolves' adaptable life-history 
characteristics, we expect wolf populations in the Western United 
States will be able to maintain their evolutionary potential and adapt 
to future change (representation). The likelihood of additional wolves 
in California and Colorado (and possibly in Arizona, New Mexico, and 
Utah in the long term), the continued recolonization of Western Oregon 
and Washington, and the availability of suitable wolf habitat and prey 
further support the continued viability of the gray wolf in the Western 
United States under the existing management commitments, albeit at 
potentially reduced population sizes compared to current numbers 
(Service 2023, pp. 135-188).
    According to our analysis of the best available scientific and 
commercial data, now and into the foreseeable future, wolves in the 
Western United States are projected to withstand environmental and 
demographic stochasticity, increased human-caused mortality, potential 
disease events, and changing environmental conditions. Given the 
natural resiliency of wolf populations (e.g., high fecundity, dispersal 
abilities), the conservation

[[Page 8395]]

efforts and regulatory mechanisms in place reinforce that States within 
the Western U.S. metapopulation will continue to manage human-caused 
mortality such that this stressor does not compromise the current or 
future viability of the metapopulation.
    Specifically, now and into the foreseeable future, wolves are 
likely to retain a healthy level of abundance. Given the assumptions in 
our model (Service 2023a, pp. 181-186), our analysis of our model 
projections indicates that there is no risk of quasi-extinction in the 
next 100 years under any of our future scenarios. More specifically, 
according to the population projections from our forecasting model 
(Service 2023, pp. 185-188), which incorporates Idaho, Montana, and 
Wyoming's minimum management commitments since delisting (Service 2023, 
pp. 163-164), we project there would be at least 739 wolves throughout 
Idaho, Montana, Oregon, Washington, and Wyoming for the next 100 years 
(Service 2023, pp. 185-188) (according to the lower credible interval 
of the population projection from the most impactful combination of 
disease and harvest scenarios we analyzed, scenarios we find unlikely 
for the reasons explained in the SSA Report (Service 2023, pp. 172-
177)). If states continue to harvest wolves at past observed rates of 
harvest (Harvest Scenario 1), which they have yet to significantly 
exceed despite implementing less-restrictive regulations and which are 
more consistent with new management objectives in Idaho (IDFG 2023b, 
pp. 39-42), the projected population size would remain above 
approximately 1,300 to 1,600 wolves for the next 100 years, even with 
catastrophic levels of disease (Service 2023, pp. 185-188). Prey and 
habitat are not limiting and are not likely to become so. Wolves are 
also likely to retain their connectivity within the Western United 
States and to Canada, supporting healthy levels of genetic diversity. 
Wolves are also likely to be able to withstand catastrophic events 
(i.e., disease) now and into the foreseeable future, given their 
retention of a wide distribution, their high fecundity, and the fact 
that our models indicate the population would not crash due to 
catastrophic disease events. Finally, wolves currently have the ability 
to and will retain the ability to adapt to changes in their environment 
given their retained distribution across a diversity of ecoregions 
(even with projected future population declines in Idaho and Montana), 
their generalist life history, and their genetic diversity. Thus, after 
assessing the best available data, we conclude that the gray wolf in 
the Western United States is not in danger of extinction or likely to 
become so in the foreseeable future throughout all of its range.
    Having concluded that gray wolves in the Western United States are 
not in danger of extinction or likely to become so in the foreseeable 
future throughout their range, we also evaluated four different 
potential significant portions of the range: (1) Idaho; (2) Montana; 
(3) California, Western Oregon, and Western Washington; and (4) the 
NRM. We determined that, due to the current and projected demographic 
health of these portions and the existing regulatory mechanisms, none 
of these portions are in danger of extinction or likely to become so in 
the foreseeable future (i.e., none of these portions have a different 
status than the gray wolf throughout its entire range in the Western 
United States, now or into the foreseeable future). After assessing the 
best available data, we concluded that the gray wolf in the Western 
United States is not in danger of extinction, or likely to become in 
danger of extinction in the foreseeable future, throughout all of its 
range or in any significant portion of its range. Therefore, we find 
that listing the gray wolf in the Western United States as an 
endangered species or a threatened species under the Act is not 
warranted. A detailed discussion of the basis for this finding can be 
found in the species assessment form and other supporting documents 
(see ADDRESSES, above).

Peer Review

    In accordance with our July 1, 1994, peer review policy (59 FR 
34270; July 1, 1994) and the Service's August 22, 2016, Director's Memo 
on the Peer Review Process, we solicited independent scientific reviews 
of the information contained in the SSA report for the gray wolf in the 
Western United States. On behalf of the Service, an outside contractor 
sent the SSA report to five independent peer reviewers and received 
five responses. Results of this structured peer review process can be 
found at https://www.regulations.gov. We incorporated the results of
