This dataset contains thespecies richness (total number of CEs) value for each 5th level HUC was calculated using the fine-filter. CE richness for the terrestrial EI was calculated by summing the number of fine-filter terrestrial CEs occurring in each HUC based on the distribution outputs used for the fine-filter CE analysis. These species included the grizzly bear, greater sage-grouse (GRSG), golden eagle, mule deer, elk, bighorn sheep, Canada lynx, American marten, and the wolverine CEs in the Middle Rockies ecoregion.

The Randomized Shortest Path (RSP) raster delineates potential dispersal paths for male-mediated gene flow between grizzly bear (Ursus arctos) populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE). A RSP algorithm was used to estimate the average number of net passages for all grid cells at a spatial resolution of 300 m in the study region which spans parts of Montana, Idaho, and Wyoming. RSP rasters identify potential movement paths for 3 levels of random deviation determined by the parameter Θ (i.e., Θ = 0.01, 0.001, and 0.0001) for bears moving from an origin to a destination node. Lower values of Θ result in greater exploration and more random deviation around...

The Madison Valley is an important wildlife linkage zone between core habitats at the center of the Greater Yellowstone Ecosystem (GYE) and habitats at the western edge of the GYE and beyond. This report identifies lands in the Madison Valley watershed which are significant for conservation based on the common occurrence of key threats to wildlife and their critical habitats and migration corridors. The species emphasized in this report - grizzly bear, wolverine, and pronghorn antelope - were selected for their need to move across or along the valley to maintain traditional migration routes, enable genetic exchange across the valley, or expand into unoccupied habitat. The selected species are also intended to serve...

Establishing connections among natural landscapes is the most frequently recommended strategy for adapting management of natural resources in response to climate change. The U.S. Northern Rockies still support a full suite of native wildlife, and survival of these populations depends on connected landscapes. Connected landscapes support current migration and dispersal as well as future shifts in species ranges that will be necessary for species to adapt to our changing climate. Working in partnership with state and federal resource managers and private land trusts, we sought to: 1) understand how future climate change may alter habitat composition of landscapes expected to serve as important connections for wildlife,...

The Grizzly Bear Recovery Zone (GBRZ) for the Greater Yellowstone Ecosystem (GYE) delineates the area inside the GYE where demographic and habitat criteria were applied, monitored, and evaluated to achieve recovered status of the Yellowstone grizzly bear population. The GBRZ was established by the U.S. Fish and Wildlife Service (USFWS) in 1993 as part of the Recovery Plan for grizzly bears in the lower 48 conterminous United States. The recovery zone boundary identifies the known distribution of bears at that time and encompasses seasonal habitats needed to support a recovered population. The GYE recovery zone spans portions of Montana, Idaho and Wyoming and includes parts of 5 National Forests (Beaverhead-Deerlodge,...
The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2004-2018. 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 2004 to 2018.

The Conservation Strategy Management Area (CSMA) is an area within which a delisted Yellowstone grizzly bear population was managed with the objective to maintain a stable to increasing population. The CSMA was formalized in the 2007 Federal Rule (72 FR 14866) which removed the Yellowstone distinct population segment from Federal protection as a threatened species under the Endangered Species Act. The CSMA was delineated as the area from within which the Yellowstone grizzly bear population size was estimated and sustainable mortality thresholds and demographic criteria were applied. The decision to replace the CSMA boundary with the Demographic Monitoring Area was first approved by the Yellowstone Ecosystem Subcommittee...

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).
Flight Observation Units, also referred to as Bear Observation Areas (BOAs), were delineated by the Interagency Grizzly Bear Study Team (IGBST) to facilitate systematic aerial monitoring of the grizzly bear population within the Greater Yellowstone Ecosystem. Flight units were last updated in 2014 to depict 54 distinct observation areas spanning the spatial extent of the Demographic Monitoring Area established for the Yellowstone grizzly bear population.

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...

The 2016 Food Storage Order (FSO) boundary layer depicts those areas on Federal lands within the Greater Yellowstone Ecosystem (GYE) where legal requirements pertaining to safe storage, possession, and handling of food and other grizzly bear attractants are implemented. FSOs give Forest Supervisors and National Park Superintendents the authority to close or restrict the use of designated areas under their jurisdiction in order to minimize human/grizzly bear conflicts. As of 2016, FSOs are prescribed on 98% of all Forest and Park Service lands inside the grizzly bear demographic monitoring area of the GYE. FSOs help facilitate connectivity between the Yellowstone grizzly bear and adjacent populations by minimizing...
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.
