Map containing historical census data from 1900 - 2000 throughout the western United States at the county level. Data includes total population, population density, and percent population change by decade for each county. Population data was obtained from the US Census Bureau and joined to 1:2,000,000 scale National Atlas counties shapefile.

Probability map of deer mouse occurrence in relation to vegetation, abiotic, and anthropogenic features. These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release.

Map of pronghorn distribution developed from a probability of occurrence map created using multi-scale vegetation, abiotic, and anthropogenic features. These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release.

This map was developed to examine multi-scale spatial relationships between percentage of sagebrush and other response variables of interest. A map of sagebrush in the western United States was used as a base layer for a moving window analysis to calculate the percentage of the area classified as sagebrush within a 5-km search radius.

Model of habitat utilization by synanthropic avian predators: common ravens (Corvus corax), American crows (Corvus brachyrhynchos), and black-billed magpies (Pica hudsonia). The former two species show increasing nation-wide population trends, and common ravens in the Mojave desert have been shown to have detrimental effects on threatened desert tortoise (Gopherus agassizii) populations. Power lines are used by common ravens and other raptors for nesting and as hunting perches. Linear features such as railroads, primary and secondary roads, and irrigation channels often serve as travel routes for these predators, and expand their movements into previously unused regions. Numbers of synanthropic avian predators increase...
