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 Wind River Indian Reservation is an area encompassing approximately 9,000 square kilometers in northwest Wyoming shared by the Eastern Shoshone and Northern Arapaho tribes of the Native American Indian Nations. The boundary feature was generated by the U.S. Geological Survey to represent the external boundary of the reservation at a scale of 1:500,000.

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 grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 1980-1989. 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 1980 to1989.

Aquatic invasive species are often transported between water bodies on boats or boat trailers, thus they are considered one of the primary vectors for new introductions of invasive species to a water body. This data set contains geographic positioning system locational data for boater access points, use data (i.e. recreational, fishing), water quality measurements (e.g. calcium concentrations, pH), risk assessment data, and other physical attributes (i.e. size, elevation) where available within the Columbia and Snake Rivers and throughout the Columbia River Basin. This work builds on an earlier body of work by Wells et al. 2011, Prioritizing Zebra and Quagga Mussel Monitoring in the Columbia River Basin (PDF link...

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...

This dataset provides numbers of documented mortalities for independent aged ( ≥ 2-years-old) grizzly bears (Ursus arctos) from human and undetermined causes that occurred during 1998–2017 within 49-km2 (7- x 7-km) grid cells from the Greater Yellowstone (GYE) and Northern Continental Divide (NCDE) ecosystems of the western United States.

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.

This dataset consists of point features identifying indices for potential passage rate at intersections with major transportation corridors for grizzly bear movements between the Greater Yellowstone Ecosystem (GYE) and Northern Continental Divide Ecosystem (NCDE) in the northwestern United States. Points are spaced at 300-meter intervals along major road corridors (interstates and U.S. highways) and are populated with values from Randomized Shortest Path (RSP) predictive raster models of potential male grizzly bear movement between the two ecosystems as described in Peck et al. 2016 (Potential paths for male-mediated gene flow to and from an isolated grizzly bear population, Ecosphere 8(10):e01969). RSP scores extracted...

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.

Side channels are small channels located parallel to the main channel of river that have a surface connection to the river at the upstream and/or downstream end. Connectivity may depend on river stage. Side channels are an important type of off-channel habitat for rearing of juvenile salmon and spawning by adults.

We analyzed detection/non-detection data from acoustic surveys of bat species in Colorado during the summers of 2016 and 2017. The goal of this analysis is to create species distribution maps estimating the probability of occupancy across the state for each species. We fit a community occupancy model using both years of data from all the available species. Spatially explicit covariates were included to explain heterogeneity in the probabilities of occupancy and nightly covariates were used to model detection. We also allowed for spatial patterns in the probability of occupancy for each species in order to account for the ranges of many species including only a portion of Colorado. This is also useful for explaining...

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.
