Data

This dataset represents a species known range extent for Spizella breweri (Brewer's Sparrow). 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 habitat distribution model for Eurasian Tree Sparrow. These habitat maps are created by applying a deductive habitat model to remotely-sensed data layers within a species' range.

This dataset represents a species known range extent for Sciurus niger avicennia (Mangrove Fox Squirrel). 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 Lepidochelys kempii (Kemp's Ridley Sea Turtle). 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 Peromyscus attwateri (Texas Deermouse). 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 Melanerpes formicivorus (Acorn Woodpecker). These range maps are created by attributing sub-watershed polygons with information of a species presence, origin, seasonal and reproductive use.

Water and its location on the landscape are important aspects of a species distribution. A number of water related data layers were used to refine these USGS Gap Analysis Project species models. These include water type (i.e. flowing, open/standing), distance to and from water, and stream flow and underlying gradient. The source for this data was the USGS National Hydrography Dataset (NHD)(USGS 20

This dataset represents a species known range extent for Anaxyrus microscaphus (Arizona Toad). 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 Tympanuchus phasianellus campestris (Prarie Sharp-tailed Grouse). 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 Egretta rufescens (Reddish Egret). 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 Oporornis philadelphia (Mourning Warbler). 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 Sorex longirostris (Southeastern Shrew). These range maps are created by attributing sub-watershed polygons with information of a species presence, origin, seasonal and reproductive use.
