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 facilitate information about the Service's programs to the public, media, Congress, Tribes, partners, and other stakeholders in the 8-state region.

Grizzly bear (Ursus arctos horribilis)
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.
May 24, 2018 - The U.S. Fish and Wildlife Service (Service) announced today the availability of the final Grizzly
Bear Recovery Plan Supplement: Habitat-Based Recovery Criteria for the Northern Continental Divide Ecosystem
(Recovery Plan Supplement). The final Recovery Plan Supplement provides objective, habitat-based criteria
for the recovery of Northern Continental Divide Ecosystem grizzly bears, and builds upon the existing roadmap to
grizzly bear recovery for the Service and our conservation partners.
December 11, 2017 - DENVER –The U.S. Fish and Wildlife Service is soliciting input from the
scientific community and the broader public on draft criteria set for the eventual recovery of the Northern
Continental Divide Ecosystem (NCDE) grizzly bear. The NCDE region encompasses Glacier National Park and other
parts of northwestern Montana.
December 6, 2017 - DENVER – Today the U.S. Fish and Wildlife Service (Service) published a
Notice of Regulatory Review (NORR) in the Federal Register requesting public comment on any potential
effects a recent D.C. Circuit Court of Appeals ruling may have on the Service’s June 30, 2017 final rule
delisting the Greater Yellowstone Ecosystem (GYE) grizzly bear Distinct Population Segment (DPS).
June 22, 2017 - WASHINGTON – Due to the success of conservation efforts and collaboration among a variety of
stakeholders, U.S. Secretary of the Interior Ryan Zinke announced today that the Yellowstone population of
the grizzly bear has been recovered to the point where federal protections can be removed and overall
management can be returned to the states and tribes. The population has rebounded from as few as 136 bears in
1975 to an estimated 700 today and meets all the criteria for delisting.
November 16, 2016 - The Yellowstone Ecosystem Subcommittee (YES) of the Interagency Grizzly Bear Committee
(IGBC) completed and accepted the Revised Draft Conservation Strategy by a vote of 18 in favor, one opposed, and
one abstention at its fall meeting in Cody, Wyoming on November 16-17, 2016. The Conservation Strategy is not
official until it is signed by the agency leaders whose staff worked and voted on the revision. It is anticipated
that this signing will take place at the IGBC annual winter meeting December
13-14, 2016 at the Holiday Inn Downtown Missoula, Montana.
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. Please see Docket No. FWS–R6–ES–2016–0042, and the supporting documents listed below:
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. The Cabinet-Yaak grizzly bear population is estimated to be approximately
50 individuals. Active research began in the Cabinet-Yaak recovery zone in 1983 when one bear was captured and
radio collared. 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. The current
population estimate within the 2,200 square mile Selkirk Mountain recovery zone is approximately 80
individuals. 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 produces genetic isolation.

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.
