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.
A complete set of wells associated with oil, natural gas, and coal bed natural gas development in the western states as of June 2004. This is a static dataset even though liquid energy development is a highly dynamic endeavor. Because these well location datasets are generally housed and managed by various state-based agencies (typically the state Oil and Gas Conservation Commissions) a uniform, spatially precise coverage for the western United States has not been available to date. This layer consolidates the best available well location data from ND, SD, MT, WY, CO, NM, UT, AZ, OR, and CA (ID and WA do not report any liquid energy development) and standardizes the attributes. While static as of June 2004 the well...
Density of linear features, such as roads, power lines, telephone lines, and railroad tracks have been shown to influence synanthropic predator abundance patterns (Knight et al. 1995). Following Knight et al. (1995), we used linear features such as roads, railroads, and power line spatial data sets, but also included irrigation canals, to build a linear features spatial data set. However, we lacked spatial data on telephone and feeder-power lines and therefore our linear feature spatial data set vastly underestimates the number of linear features in some areas.

This dataset contains information regarding the acreages of land currently (as of 2004) enrolled in the Conservation Reserve Program (CRP) distributed by county and the year the CRP contract was initiated (1987-2004, excluding 1994 and 1995). Additionally, it contains total acreages of land enrolled in the CRP distributed by county and the contract year (1987-2003). USDA Farm Service Agency's (FSA) Conservation Reserve Program (CRP) is a voluntary program available to agricultural producers to help them safeguard environmentally sensitive land. Producers enrolled in CRP plant long-term, resource-conserving covers to improve the quality of water, control soil erosion, and enhance wildlife habitat. In return, FSA...

This model was constructed to model the risk of invasion by exotic plant species. Roads may directly influence exotic plant dispersal via disturbance during road construction or via alterations in soil regimes. For example, in Californian serpentine soil ecosystems, exotic plant species can be found up to 1km from the nearest road and Russian thistle (Salsola kali), an exotic forb growing along roads, is wind-dispersed over distances greater than 4km. Roads may also indirectly facilitate the dispersal of exotic grasses, such as crested wheatgrass (Agropyron cristatum), via human seeding along road verges or in burned areas near roads as a management strategy to curb the establishment of less desirable exotic grass...
All secondary roads in the western United States from the 2000 US Census TIGER/line files. Secondary roads are defined as all roadways not classified as an interstate, state highway, or federal highway.
A summary data set of all fire polygons we could locate as of December 2007. We used multiple datasets to develop this layer, including data gathered from the internet, publically available databases, and personal contacts with dozens of agency personnel throught the western U.S. Data were assessed for utility (but not accuracy) and formatted for consistency. Each source data set was then attributed consistently with fields for record number and year (of fire). Because various resource management entities map fires somewhat independently (especially in more recent years) we merged overlapping polygons for each year. Users are encouraged to understand the contents of this data file before using it.
Boundary for floristic regions used for the conservation assessment of Greater Sage-grouse and sagebrush habitat conducted by the Western Association of Fish and Wildlife Agencies. The floristic provinces were digitized from a figure from Miller, R. F., and L. Eddleman, 2001 (See source input for reference).
