The Mountain-Prairie Region consists of 8 states in the heart of the American west including Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah and Wyoming.
The U.S. Fish and Wildlife Service has a long tradition of scientific excellence and always uses the best-available science to inform its work to conserve fish, wildlife, plants, and their habitat for the benefit of the American public.
Created in 1903 by President Theodore Roosevelt, today's National Wildlife Refuge System protects habitats and wildlife across the country, from the Alaskan tundra to subtropical wetlands. Managed by the U.S. Fish and Wildlife Service, the Refuge System's 560-plus refuges cover more than 150 million acres and protect nearly 1,400 species of birds, mammals, reptiles, amphibians, and fish.
While national wildlife refuges were created to protect wildlife, they are for people too. Refuges are ideal places for people of all ages to explore and connect with the natural world. We invite you to learn more about and visit the national wildlife refuges and wetland management districts in Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming.
The Mountain-Prairie Region's Office of Ecological Services (ES) works to restore and protect healthy populations of fish, wildlife, and plants and the environments upon which they depend. Using the best available science, ES personnel work with Federal, State, Tribal, local, and non-profit stakeholders, as well as private land owners, to avoid, minimize, and mitigate threats to our Nation's natural resources.
Providing leadership in the conservation of migratory bird habitat through partnerships, grants, and outreach for present and future generations. The Migratory Bird Program is responsible for maintaining healthy migratory bird populations for the benefit of the American people.
The U.S. Fish & Wildlife Service Fish and Aquatic Conservation Program in the Mountain-Prairie Region helps conserve, protect, and enhance aquatic resources and provides economically valuable recreational fishing to anglers across the country. The program comprises 12 National Fish Hatcheries.
Law enforcement is essential to virtually every aspect of wildlife conservation. The Office of Law Enforcement contributes to Service efforts to manage ecosystems, save endangered species, conserve migratory birds, preserve wildlife habitat, restore fisheries, combat invasive species, and promote international wildlife conservation.
External Affairs staff in the Mountain-Prairie Region of the U.S. Fish and Wildlife Service provides support to the regional office and field stations to communicate and faciliate information about the Service's programs to the public, media, Congress, Tribes, partners, and other stakeholders in the 8-state region.
When Lewis and Clark explored the West in the early 1800s an estimated 50,000 grizzly bears roamed between the Pacific Ocean and the Great Plains, across vast stretches of open and unpopulated land. But when pioneers moved in, bears were persecuted and their numbers and range drastically declined. As European settlement expanded over the next hundred years, towns and cities sprung up, and habitat for these large omnivores—along with their numbers—shrunk drastically. Today, with the western United States inhabited by millions of Americans, only a few small corners of grizzly country remain, supporting about 1,400-1,700 wild grizzly bears. Of the 37 separate grizzly populations present in 1922, 31 were extirpated by 1975.
In 1975, the Service listed the grizzly bear as a threatened species in the lower 48 states under the Endangered Species Act. There are five areas where grizzlies remain today, Yellowstone ecosystem, Northern Continental Divide ecosystem, Cabinet-Yaak ecosystem, Selkirk ecosystem, and Northern Cascades ecosystem. The grizzly bear recovery effort has met with some successes. These successes have been largely due to a cooperative effort among several organizations called the Interagency Grizzly Bear Committee, which coordinates habitat management, research, education, and outreach.

September 6, 2016 - The Service is reopening of the comment period on the proposed rule to delist the Greater Yellowstone Ecosystem grizzly bear population, which initially published March 11, 2016. This decision comes after July’s release of the findings of an extensive scientific peer review of the delisting proposal. The extended comment period also allows the public to comment on the protective measures passed by Idaho, Montana, and Wyoming for post-delisting management of grizzly bears.

March 3, 2016 - The Service is requesting public review and input on Proposed Revisions to the Demographic Recovery Criteria for the Grizzly Bear Population in the Greater Yellowstone Area Docket No. FWS–R6–ES–2016–0042. These proposed revisions and supporting documents are listed below:
Grizzly bears were listed as a threatened species in 1975 in the conterminous 48 States. Currently grizzly bear distribution has been reduced to 5 areas in the western United States, including the Bitterroot in central Idaho and western Montana. Despite numerous studies of this area, there were no verifiable sightings of grizzly bears in the last 60 years until an adult male grizzly bear was mistakenly killed by a black bear hunter is September 2007 in the northern mountains of the Bitterroot. Recovery programs include activities such as improving management of grizzly bears on public lands, genetic research, population monitoring, public education, and implementing the recovery plans for each population.
In 2007, the Service initiated a 5-year review of grizzly bear (as listed in the lower 48 States excluding the Greater Yellowstone Area population) and 8 other species (72 FR 19549).
Grizzly bears were listed as a threatened species in 1975 in the conterminous 48 States. Currently grizzly bear distribution has been reduced to 5 areas in the western United States, including the Cabinet-Yaak in northern Idaho and northwest Montana. Populations are estimated to be Active research began in both the Cabinet–Yaak and Selkirk recovery zones in 1983 when one bear was captured and radiocollared in each ecosystem. The Cabinet–Yaak ecosystem encompasses the Yaak River drainage and the Cabinet Mountains. The ecosystem is bisected by the Kootenai River, with the Cabinet Mountains to the south and the Yaak River area to the north. Approximately 90% of the study area is on public land administered by the Kootenai and Panhandle National Forests. The Cabinet Mountains Wilderness Area encompasses part of the study area at higher elevations of the Cabinet Mountains.

In 2007, the Service initiated a 5-year review of grizzly bear (as listed in the lower 48 States excluding the Greater Yellowstone Area population) and 8 other species (72 FR 19549).
In 2006, the Service issued a non-jeopardy biological opinion for the Revett Silver Company’s proposed Rock Creek Mine project in the Cabinet Mountains of Montana. The non-jeopardy opinion concludes that the project incorporates a conservative approach to ensure adequate measures to conserve grizzly bears and bull trout. The mitigation plan for the Rock Creek mine will be protective of threatened bull trout and should produce a positive net effect for the Cabinet-Yaak ecosystem grizzly bear population.

The North Cascades is a large ecosystem in north-central Washington State and south-central British Columbia. The largest area of the ecosystem, about 9,800 square miles, lies in the United States, with an additional 3,800 square miles across the international border in British Columbia. The North Cascades ecosystem (NCE) is isolated from other ecosystems in the United States and Canada with grizzly bear populations.
While study of this very rugged and remote habitat indicates that this ecosystem is capable of supporting a self-sustaining population of grizzlies, the population is estimated to be fewer than 20 animals within the recovery zone in the United States. The population in adjacent British Columbia portion of the ecosystem is estimated to be less than 25-30 grizzly bears. Given the low number of grizzly bears, very slow reproductive rate and other recovery constraints, the NCE grizzly bear population is the most at-risk grizzly bear population in the United States today.
The main threat to grizzly bears in this recovery zone is a small population size and population fragmentation, with resulting demographic and genetic risks.
In 2013, The Fish and Wildlife Service reaffirmed (78 Fed. Reg. 70104 [Nov. 22, 2013]) that the North Cascades ecosystem grizzly bear warrants uplisting from Threatened to Endangered under the Endangered Species Act.
To date, efforts toward recovery in the NCE have focused on habitat protection through a strategy of no net loss of core habitat, information and education efforts regarding grizzly bears and their habitat, and enhanced sanitation for proper garbage and food storage in bear habitat.

In accordance with the NCE Recovery Plan chapter (1997) and the National Environmental Policy Act of 1969 (NEPA), the National Park Service and U.S. Fish and Wildlife have jointly initiated (2014) an Environmental Impact Statement (EIS) planning process to evaluate a range of alternatives for recovering the North Cascades grizzly bear population. The Washington Department of Fish and Wildlife and the United States Department of Agriculture Forest Service are cooperating agencies in the process.
A recovery plan for the British Columbia ecosystem was completed in 2004.

Grizzly bears were listed as a threatened species in 1975 in the conterminous 48 States. Currently grizzly bear distribution has been reduced to 5 areas in the western United States, including the Northern Continental Divide in northwestern Montana. The grizzly population in this area includes Glacier National Park and adjacent areas in Canada, and the Bob Marshall Wilderness Complex. This population has approximately 1,000 animals and continues to grow each year.
May 2, 2013 – A draft conservation strategy for grizzly bears in the Northern Continental Divide Ecosystem (NCDE) is now available for public review and feedback. This document describes the management and monitoring programs that would be in place if and when this population is delisted from the Endangered Species Act. These measures are designed to maintain a recovered grizzly bear population in the NCDE. This document does not change the legal status of this population of grizzly bears. The U.S. Fish and Wildlife Service will not sign this conservation strategy or delist this population until agencies demonstrate their commitment to implementing it.

On April 18, 2007, the Fish and Wildlife Service announced the initiation of a 5-year review of grizzly bear (Ursus arctos horribilis) (as listed in the lower 48 States excluding the Greater Yellowstone Area population) and 8 other species (72 FR 19549). We conducted reviews to ensure that our classification of each species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants is accurate. A 5-year review is an assessment of the best scientific and commercial data available at the time of the review.
Funding was received in 2003 to begin the process to determine the total number of bears in this ecosystem with statistical confidence. Additional population monitoring ecosystem wide is necessary to further recovery and any potential delisting.
More than 17% of this ecosystem is private land and the majority of bear-human conflicts and bear deaths occur on these private lands. We must continue to work with private landowners to minimize these conflicts.

Grizzly bears were listed as a threatened species in 1975 in the conterminous 48 States. In 1999, the Fish and Wildlife Service first issued a warranted but precluded finding to uplist the Selkirk Mountains recovery zone population to endangered status. As noted in the recently published Annual Notice of Findings on Resubmitted Petitions, this uplisting action continues to be precluded by higher priority listing actions (see the species assessment form for additional information on why reclassification is warranted but precluded).
Current grizzly bear distribution has been reduced to 5 areas in the western United States, including the Selkirk Mountains in northern Idaho and northeast Washington, and southeast British Columbia. Populations are estimated to be 40-50 animals within the 2,200 square-mile Selkirk Mountains recovery zone. Threats to the species in this recovery zone include incomplete habitat protection measures (motorized access management), overutilization by human-caused mortality, small population size, and population fragmentation that produce genetic isolation. The Service assigned a listing priority number of 3 to this population due to continuing high levels of human caused mortality in British Columbia and new genetic information indicating the population is isolated and has declined in genetic diversity relative to both adjacent populations.

November 15, 2011 – The 9th Circuit Court of Appeals issued an opinion affirming in part and reversing in part the district court’s decision vacating the final rule delisting grizzly bears in the Greater Yellowstone Area. The Appellate court affirmed the U.S. Fish and Wildlife Service’s determination that existing regulatory mechanisms are adequate to protect grizzlies in the Yellowstone area while ruling that the Service had failed to adequately explain its conclusion that the loss of whitebark pine was not a threat to the population. In compliance with this order, the Greater Yellowstone Area population of grizzly bears remains federally listed as “threatened” under the Endangered Species Act while we consider more recent scientific data.
September 21, 2009 – The Federal District Court in Missoula issued an order vacating the delisting of the Greater Yellowstone Area grizzly population. In compliance with this order, the Yellowstone grizzly population was once again a threatened population under the Endangered Species Act (75 FR 14496, March 26, 2010). The District Court ruled that the Service was arbitrary and capricious in its evaluation of white bark pine and that the regulatory mechanisms identified in the final rule were not adequate because they were not legally enforceable.
March 22, 2007 – The U.S. Fish and Wildlife Service announced that the Greater Yellowstone Area population of grizzly bears was recovered and should be removed from the Federal list of threatened and endangered species.

Reinstatement of Protections for the Grizzly Bear in the Greater Yellowstone Ecosystem in Compliance With Court Order (75 FR 14496) (March 26, 2010)
On March 22, 2007, the U.S. Fish and Wildlife Service (Service) announced that the Yellowstone Distinct Population Segment (DPS) of grizzly bears is a recovered population no longer meeting the ESA’s definition of threatened or endangered. This DPS has increased from estimates as low as 136 individuals when listed in 1975 to more than 500 animals as of 2006. This population has been increasing between 4 and 7 percent annually. The range of this population also has increased dramatically as evidenced by the 48 percent increase in occupied habitat since the 1970s. Yellowstone grizzly bears continue to increase their range and distribution annually and grizzly bears in the Yellowstone area now occupy habitats they have been absent from for decades. Currently, roughly 84-90 percent of females with cubs occupy the Primary Conservation Area (PCA) and about 10 percent of females with cubs have expanded out beyond the PCA within the DPS boundaries. Grizzly bears now occupy 68 percent of suitable habitat within the DPS boundaries and may soon occupy the remainder of the suitable habitat.
Intensive monitoring of the population and its habitat will continue so that managers can continue to base management decisions on the best available scientific information. The Yellowstone DPS represents a viable population which has sufficient numbers and distribution of reproductive individuals so as to provide a high likelihood that the species will continue to exist and be well distributed throughout its range for the foreseeable future. The State and Federal agencies are committed to implementing the extensive Conservation Strategy and State management plans. They have formally incorporated the habitat and population standards described in the Conservation Strategy into the six affected National Forests' Land Management Plans and Yellowstone and Grand Teton's National Park Compendiums. This commitment coupled with State wildlife agencies' approved grizzly bear management plans ensure that adequate regulatory mechanisms are in place and that the Yellowstone grizzly bear population will not become an endangered species within the foreseeable future throughout all or a significant portion of its range. Therefore, based on the best scientific and commercial information available, we are finalizing the delisting of the Yellowstone grizzly bear DPS. More information on this action and other post-delisting management documents are available below.
