The Suitable Habitat boundary identifies areas inside the Greater Yellowstone Ecosystem where habitat is deemed suitable for supporting a viable and self-sustaining Yellowstone grizzly bear population into the foreseeable future. The boundary was established by the U.S. Fish and Wildlife Service (USFWS) and formalized in the 2007 Final Rule to remove the Yellowstone grizzly bear from federal protection as a Threatened species under the Endangered Species Act (72 FR 14866 – currently vacated).

The Distinct Population Segment (DPS) boundary is an area formalized in the 2007 Final Delisting Rule (72 FR 14866) which designates the Greater Yellowstone Ecosystem (GYE) population of grizzly bears (Ursus arctos horribilis) as a single and distinct population from the remaining populations in the lower 48 States. The U.S. Fish and Wildlife Service applied the DPS policy based on the discreteness and significance of the Yellowstone population segment in relation to the remainder of the taxon in the conterminous 48 States.

Grizzly bear recovery zones were established by the U.S. Fish and Wildlife Service in 1993 to delineate regions in the lower 48 states that have sufficient habitat to target recovery for five, and possibly six remnant grizzly bear populations. Recovery zones represent the five known populations in the lower 48 United States including the Northern Continental Divide, Greater Yellowstone, Cabinet-Yaak, Selkirk, and North Cascade populations. The bitterroot ecosystem in Idaho represents the possible sixth population. The grizzly bear once ranged across a large portion of western North America from northern Mexico to Alaska and across much of Canada. Current distribution in the lower 48 United States is reduced to less...

Bear Management Units (BMUs) are management areas within the Grizzly Bear Recovery Zone (GBRZ) that were delineated by the Interagency Grizzly Bear Study Team (IGBST) to assist in managing habitat and monitoring population trends of the Yellowstone grizzly bear population. BMU areas approximate the size of the lifetime range of an average adult female and reflect areas of biological relevance to grizzly bears in the Greater Yellowstone Ecosystem (GYE). The GBRZ was divided into 18 distinct BMUs to facilitate monitoring and ensure that adequate habitat and numbers of grizzly bears are well distributed throughout the GYE recovery zone.

This ArcView shapefile contains a representation of the boundary of the Ferris coalfield in the Hanna Basin, Wyoming. This theme was created specifically for the National Coal Resource Assessment in the Northern Rocky Mountains and Great Plains Region.

The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2000-2014. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 2000 to 2014.

The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2002-2016. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 2002 to 2016.

The Wyoming Landscape Conservation Initiative (WLCI) Boundary was buffered by 10 KM and intersected with the U.S. USGS 1:100,000 Topographic Quadrangle Series Index. The intersecting quadrangles were clipped, and then the quad boundary lines dissolved to form the Area of Interest for the WLCI.

This ArcView shapefile contains a polygon representation of the Deadman coal zone in the Black Butte area of the Point of Rocks-Black Butte coalfield, Wyoming. This boundary is a part of the National Coal Resource Assessment of the Northern Rocky Mountain and Great Plains Fort Union Coal Resources Assessment Area. This coal zone can be shown in relation to other relevant themes of this area.

This ArcView shapefile contains a polygon representation of the northern boundary of the Powder River Basin (Montana). This theme was created specifically for the National Coal Resources Assessment in the Northern Rocky Mountains and Great Plains Region.

The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 1990-2000. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 1990 to 2000.

Management units for Ellicott Slough NWR. These boundaries were updated as part of the Comprehensive Conservation Plan in 2009.

The Demographic Monitoring Area (DMA) is the boundary within which all demographic criteria for the Yellowstone grizzly bear population are currently monitored and evaluated. The DMA replaces the Conservation Strategy Management Area (CSMA) as the area within which total grizzly bear population size is estimated and biologically sustainable mortality thresholds are established. All grizzly bear observations and mortalities inside the DMA are counted toward population estimates and mortality thresholds; however, observations outside the monitoring area are also recorded and reported by the Interagency Grizzly Bear Study Team.

Bear management subunits are subdivisions of larger bear management units (BMUs) that make up the Grizzly Bear Recovery Zone (GBRZ) located at the core of the Greater Yellowstone Ecosystem (GYE). Subunits were delineated to assist in the management and monitoring of grizzly bear habitat and population trends. The 18 BMUs comprising the Yellowstone GBRZ were subdivided into a total of 40 subunits to provide greater landscape resolution and to account for seasonal heterogeneity of grizzly bear use patterns within a BMU. Subunits were typically delineated at the scale of the average annual home range of an adult female grizzly bear in the GYE and typically consist of a major drainage enclosed by segments of intervening...

The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 1973-1979. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 1973 to1979.

This data set represents the Wildlife Habitat Management Area boundaries. The Wyoming Game and Fish Department, under the direction of the Wyoming Game and Fish Commission, administers lands and public easement areas that are home to vast numbers of fish and wildlife. The department maintains approximately 413,000 acres of land under deed, lease or by agreement and continually strives to acquire new access areas. These areas include access to nearly 225 miles of streams, over 21,000 lake surface areas, and more than 148 miles of road right-of-ways. Management of these lands demonstrates our state's commitment to its precious wildlife heritage and those people who seek to enjoy our wildlife and wild lands.Wyoming's...
