The Gunnison sage-grouse (Centrocercus minimus) habitat suitability surface for San Miguel satellite population represented here reflects breeding season at a landscape scale context (window extents [radius] of 1 km, 3 km, and 6.4 km). Habitat suitability estimated for Colorado Parks and Wildlife critical habitat extent (southwestern Colorado). The critical habitat defined by Colorado Parks and Wildlife (CPW) is similar to the U.S. Fish and Wildlife Service critical habitat, but due to a lack of mapped urban features, we did not extrapolate models beyond the CPW boundary. We developed habitat selection models for Gunnison sage-grouse (Centrocercus minimus), a threatened species under the U.S. Endangered Species...

These are geospatial data that characterize the distribution of polar bear denning habitat on the National Petroleum Reserve–Alaska (NPR-A), the 1002 Area of the Arctic National Wildlife Refuge and the coastal plain of northern Alaska between the Colville River and the Alaska/Canada border.
These data describe differences in percent cover of microhabitats and vegetation types at giant gartersnake locations and random points paired with giant gartersnake locations for use in case-control logistic regression. The data also include information on the individual snake, the year of observation, and whether the individual had moved from its previous location to allow for correlation of the data within individuals and locations

Conversion of native winter range into producing gas fields can affect the habitat selection and distribution patterns of mule deer (Odocoileus hemionus). Understanding how levels of human activity influence mule deer is necessary to evaluate mitigation measures and reduce indirect habitat loss to mule deer on winter ranges with natural gas development. We examined how 3 types of well pads with varying levels of vehicle traffic influenced mule deer habitat selection in western Wyoming during the winters of 2005–2006 and 2006–2007. Well pad types included producing wells without a liquids gathering system (LGS), producing wells with a LGS, and well pads with active directional drilling. We used 36,699 Global Positioning...

Step selection functions use animal movement patterns to estimate habitats available at each step along a movement track. These data were generated from four species of waterfowl (Anser albifrons [greater white-fronted goose], Anser caerulescens caerulescens [lesser snow goose], Anas platyrhynchos [mallard], Anas acuta [northern pintail]) using the Central Valley of California 2016 to 2022 that were fit with tracking devices collecting GPS data every hour (or subset to hourly locations). Observed movements were used to estimate a 2-mixture log-normal step length distribution for each species. The shorter mean step length mixture generally reflected step lengths consistent with individual immobility and GPS errors....

The Gunnison sage-grouse (Centrocercus minimus) habitat suitability surface for Cerro Summit-Cimarron-Sims satellite population represented here reflects breeding season at a patch scale context (30 m x 30 m pixel and radius window extents [radius] of 45 m, 120 m, 180 m, 270 m, 390 m, and 570 m). Habitat suitability estimated for areas constrained within the thresholded landscape model (containing 95% of use locations) developed for Colorado Parks and Wildlife critical habitat extent (southwestern Colorado). This population did not have sufficient use locations to model habitat, and therefore, we extrapolated the Crawford population (nearest and considered most similar to Cerro Summit-Cimarron-Sims habitat) models...
This data release includes three types of data used in habitat modeling, and predictions from the habitat models. (1) Predictor rasters for proportion urban development within 1-km radius, proportion exurban within 1-km radius, vector ruggedness measure (VRM) within 500-m radius, topographic position index (TPI) within 500-m radius. (2) Twenty-nine null models for space use for 29 different golden eagles. (3) Twenty-nine response variable rasters of eagle locations per cell for 29 golden eagles. (4) A raster for predicted population-level probability of habitat selection and contours for predicted population-level probability of habitat selection and contours. These data support the following publication: Tracey,...

Habitat suitability estimated for Colorado Parks and Wildlife critical habitat extent (southwestern Colorado).

However, roads were not digitized for the Cerro Summit-Cimarron-Sims population, so we selected the top model from Crawford that did...

The Gunnison sage-grouse (Centrocercus minimus) habitat suitability surface for Pinyon Mesa satellite population represented here reflects summer season at a landscape scale context (window extents [radius] of 1 km, 3 km, and 6.4 km). Habitat suitability estimated for Colorado Parks and Wildlife critical habitat extent (southwestern Colorado). We developed habitat selection models for Gunnison sage-grouse (Centrocercus minimus), a threatened species under the U.S. Endangered Species Act. We followed a management-centric modeling approach that sought to balance the need to evaluate the consistency of key habitat conditions and improvement actions across multiple, distinct populations, while allowing context-specific...
The Mexican spotted owl (Strix occidentalis lucida) is a threatened subspecies whose recovery depends, in part, on both an understanding of its habitat requirements and the protection of its habitat. Therefore, we evaluated habitat composition and configuration around owl sites in the Tularosa Mountains, New Mexico, using a vegetation map derived from Landsat Thematic Mapper (TM) digital imagery and digital elevation models. Owls occupied sites with more mature mixed-conifer and mature pine and less pinyon-juniper than random sites. No difference existed in the amount of young forest between owl and random sites. After correcting for the area of the vegetation classes within owl territories, no difference existed...

We used radio-telemetry to study the movements and habitat use of Western toads (Bufo boreas) in the Targhee National Forest in southeastern Idaho. Eighteen toads (10 male and 8 female) that bred in a seasonally flooded pond, were fitted with radio-transmitters, tracked, and their movements mapped and analyzed with global positioning and geographic information systems. We also analyzed their patterns of habitat selection at micro- and macro-scales by comparing sites used by toads with randomly selected sites. After breeding, two male and six female toads left the breeding pond and used terrestrial habitats extensively. Male and female toads showed different patterns of movement and habitat use, although all toads...

These data describe coarse habitat use, activity information, and differences between used and available microhabitats and vegetation types to provide information about the behavior and habitat relationships of adult female giant gartersnakes (Thamnophis gigas) associated with a restored marsh in the Sacramento Valley of California. These data support the following publication: Brian J. Halstead, Patricia Valcarcel, Glenn D. Wylie, Peter S. Coates, Michael L. Casazza, and Daniel K. Rosenberg (2016) Active Season Microhabitat and Vegetation Selection by Giant Gartersnakes Associated with a Restored Marsh in California.

California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, including coastal dunes, remains obscure. To avoid and minimize potential negative effects of dune restoration activities, we studied the spatial ecology, habitat selection, and survival of California Red-legged Frogs in coastal dune drainages at Point Reyes National Seashore, California. Frogs remained in their home drainages throughout the summer, and, with some notable exceptions, most remained close to water. Home ranges of California Red-legged Frogs in dunes were generally small, and they selected areas near water with logs that served...
