Data

This dataset represents a species known range extent for Pantherophis vulpina (Western Foxsnake). These range maps are created by attributing sub-watershed polygons with information of a species presence, origin, seasonal and reproductive use.

This dataset represents a species known range extent for Crotalus oreganus (Western Rattlesnake). These range maps are created by attributing sub-watershed polygons with information of a species presence, origin, seasonal and reproductive use.

This dataset represents a species known range extent for Microtus ochrogaster (Prairie Vole). These range maps are created by attributing sub-watershed polygons with information of a species presence, origin, seasonal and reproductive use.

GAP species range data are coarse representations of the total areal extent a species occupies, in other words the geographic limits within which a species can be found (Morrison and Hall 2002). These data provide the geographic extent within which the USGS Gap Analysis Project delineates areas of suitable habitat for terrestrial vertebrate species in their species' habitat maps. The range maps ar

Gap Analysis Project (GAP) habitat maps are predictions of the spatial distribution of suitable environmental and land cover conditions within the United States for individual species. Mapped areas represent places where the environment is suitable for the species to occur (i.e. suitable to support one or more life history requirements for breeding, resting, or foraging), while areas not included

This dataset was used in the USGS Gap Analysis Project (GAP) species habitat distribution modeling process. Processing constraints made it impractical to model the species habitat distributions across the full conterminous U.S. in one model. The modeling regions were used to stratify the lower 48 states into modeling extents that could be efficiently used in our workflow. The regions were based on
