Density of oil and gas wells within a 270-m radius developed using a circular focal moving window analysis.
Proportion of Salt Desert Shrub Land Cover (5-km scale) in the Wyoming Basins Ecoregional Assessment area
Proportion of salt desert shrub land cover within a 5-km radius developed using a circular focal moving window analysis.
Greater sage-grouse (Centrocercus urophasianus) have been declining both spatially and numerically throughout their range due to anthropogenic disturbance and loss and fragmentation of sagebrush (Artemisia spp.) habitats. Understanding how sage-grouse respond to these habitat alterations and disturbances, particularly the types of disturbances and extent at which they respond, is critical to designing management actions and prioritizing areas of conservation. To address these needs, we developed this spatially explicit model of the relationship between occurrence and abundance of greater sage-grouse and multi-scaled measures of vegetation, abiotic, and disturbance in the Wyoming Basins Ecoregional Assessment (WBEA)...

Density of oil and gas wells within a 3-km radius developed using a circular focal moving window analysis.
A summary data set of all fire polygons we could locate as of December 2007 . We used multiple datasets to developed 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. Data may...
