Ecoregions are based on perceived patterns of a combination of causal and integrative factors including land use, land surface form, potential natural vegetation, and soils (Omernik, 1987).

This map depicts the proportion of non-Sage-grouse habitat with 18km of each pixel. The map was produced using a moving window analysis on the Distribution of Non-Sage Grouse Habitat in the Conservation Assessment Area with a search radius of 18km. The product of the moving window was the mean pixel value within the window. This map has a 540m resolution.

Locations of oil and gas wells in 11 western states. Data was obtained from the National Oil and Gas Assessment.

This multi-tiered, broad-scale, hierarchical system of ecoregions is based on numerous environmental variables at each level. The first two tiers are based on climate, followed by climate and physiograpghy, and finally topography and soils. This data was used to provide a general description of the ecosystem geography.
