Estimated potential for sage-grouse movement among sage-grouse leks (Circuitscape; McRae 2006). Rescaled HSI values were used as a measure of landscape resistance
thumbnail
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. Provides 5-km scale proportion of sagebrush land cover for use in examining multi-scale relationships.

This map depicts the distribution of existing vegetation types contained in the LANDFIRE dataset. All 30-meter EVT grids were resampled to 90-meter grids and merged to create the final product.

Humans have dramatically altered wildlands in the western United States over the past 100 years by using these lands and the resources they provide. Anthropogenic changes to the landscape, such as urban expansion, construction of roads, power lines, and other networks and land uses necessary to maintain human populations influence the number and kinds of plants and wildlife that remain. We developed the map of the human footprint for the western United States from an analysis of 14 landscape structure and anthropogenic features: human habitation, interstate highways, federal and state highways, secondary roads, railroads, irrigation canals, power lines, linear feature densities, agricultural land, campgrounds, highway...

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.

Habitat similarity index (HSI) values for greater sage-grouse across their western range. HSI values represent the relationship of environmental values at map locations to themultivariate model of minimum requirements for sage-grouse defined by land cover, anthropogenic variables, soil, topography, and climate.
