U.S. Fish and Wildlife Service Confirms Expansion of Gray Wolf Populations in Western States

Gray wolves are no longer confined to a handful of remote strongholds in the American West. After years of legal fights and scientific review, the U.S. Fish and Wildlife Service now confirms that packs are spreading across several western states, supported by a mix of natural dispersal and targeted reintroduction. That expansion is reshaping debates over endangered species policy, livestock conflicts and what recovery should look like on a modern working landscape.

From the Pacific Northwest to the central Rockies, new data show growing numbers and wider ranges, even as federal protections remain in place across most of the contiguous United States. The agency’s latest assessments describe a species that is biologically resilient yet still dependent on coordinated state and federal management to avoid backsliding.

Federal findings show a species in guarded recovery

The U.S. Fish and Wildlife Service has spent years reexamining the gray wolf’s status, culminating in a detailed Summary of Biological that pulls together population trends across North America, Europe and Asia. That review describes gray wolves as the largest wild members of the dog family and situates western U.S. packs within a much broader circumpolar range that spans North America, Europe and Asia. The biological takeaway is that the species is highly adaptable, capable of recolonizing large territories when given legal protection and sufficient prey.

The legal context, however, remains complex. Following a federal court order in early 2022, gray wolves in the contiguous 48 states and (with the exception of certain northern populations) regained Endangered Species Act protections that had been lifted in previous rulemakings. The gray wolf has been listed under the Endangered Species Act since 1978, a status that still shapes how states can respond to conflicts and how quickly they can transition to more flexible management once recovery targets are met and the species could be delisted.

USFWS declines a new national recovery plan while affirming progress

In its latest policy move, the U.S. Fish and Wildlife Service announced that it will not develop a new nationwide recovery plan for the gray wolf, a decision that reflects both confidence in existing regional frameworks and recognition of how far the species has come since the 1970s. After reviewing the most recent available assessments of the gray wolf’s status, the agency reiterated its finding that the gray wolf is progressing toward recovery, relying on a mix of population data, habitat modeling and threat analyses described as an extensive assessment. Federal officials argue that current tools and regional plans already provide a roadmap for continued gains.

The gray wolf has been listed under the Endangered Species Act since 1978, which has granted the species broad protection to promote recovery. According to agency explanations, that long history of protection, combined with strong state programs in places like the northern Rockies and western Great Lakes, informed the conclusion that an additional nationwide plan is not necessary, even as litigation and political pressure continue. The finding follows years of scientific review and, as one summary of the announcement noted, came after the Biden administration had previously signaled interest in a new planning effort, a shift that illustrates how dynamic gray wolf policy remains at the federal level.

Oregon and Washington data confirm steady pack growth

Nowhere is the westward expansion more evident than in the Pacific Northwest, where Oregon and Washington have seen steady increases in both pack numbers and occupied range. In Oregon, wildlife officials report that the minimum known count of wolves at the end of 2024 was 204 wolves, up from 178 the previous year, according to the Oregon Wolf monitoring program. That jump from 178 to 204 reflects not only reproduction within established packs but also dispersal into new parts of the state, including areas of private rangeland where coexistence tools are being tested in real time.

North of the Columbia River, Washington has moved from a handful of confirmed packs to a complex statewide management challenge. State biologists report that in general, about 80% of known wolf packs in Washington have not been involved in any documented livestock depredation in any given year, based on depredation records from 2021 to 2025. That figure, cited in a February monthly wolf report, has become a key talking point for those arguing that nonlethal deterrence, careful range riding and early conflict prevention can keep most packs out of trouble even as overall numbers climb.

Colorado’s reintroduction pause highlights tensions over pace and process

Farther inland, Colorado has emerged as a test case for how intentional reintroduction intersects with natural expansion from neighboring states. Voters there approved a ballot measure directing state officials to restore gray wolves to the Western Slope, and the first releases began in late 2023. Yet the rollout has already hit a political and logistical speed bump. Colorado Parks and Wildlife announced from Colorado that it currently has no plans for translocating additional wolves for the 2025 to 2026 release season, a decision framed as a pause to evaluate existing packs and refine conflict mitigation.

In a detailed statement from DENVER, Colorado Parks and (CPW) explained that the agency currently has no plans for translocating additional wolves during the 2025 to 2026 gray wolf release season and instead will focus on providing the tools and support needed to help minimize conflict. That decision came shortly before local reporting confirmed that, despite previous plans for gray wolf releases in Gunnison County this winter, that plan has officially been cancelled. Colorado Pa officials cited both logistical constraints and federal conditions as reasons for stepping back, illustrating how sensitive the timing and location of each release can be when ranchers, recreation interests and conservation groups are all watching closely.

Legal uncertainty and local conflict shape the next phase of recovery

As numbers rise in Oregon, Washington and Colorado, the legal footing that underpins wolf management remains unsettled. The status of gray wolves under federal law has been debated and litigated for many years, and the level of protection for the species has changed several times as courts and agencies revisit Endangered Species Act decisions. That churn has left state agencies juggling overlapping rules, from full federal protection in much of the West to more flexible frameworks in areas where wolves were previously delisted, and it complicates long term planning for ranchers, hunters and rural communities.

Even with that uncertainty, the U.S. Fish and Wildlife Service has tried to anchor its decisions in a transparent record. The agency’s latest findings integrate years of field surveys, population modeling and public comment, a process summarized in an agency update that followed years of scientific review and came just one year after the Biden administration announced its intent to develop a fresh approach. That same update emphasized that the gray wolf has been listed under the Endangered Species Act since 1978, and that any move toward delisting will require clear evidence that regional populations are secure and that state plans can prevent renewed declines.
