This map was developed to show the distribution of human influence in the western United States. This dataset was developed from the Human Footprint inthe western United States (Leu et al. 2008) in order to ease the interpretation of humand footprint comparisons. Provides the distirubtion of 3 human foorpint instensity class in the western United States.

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 was developed to examine the distribution of edge denisty between sagebrush and all other landcover types. A map of sagebrush in the western United States was used as a base layer for a moving window analysis in FRAGSTATS to calculate edge density (km/sq km) within a 5-km search radius. Provides 5-km sagebrush edge density for examining landscape connctivity and spatial metrics.

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 the multivariate model of minimum requirements for sage-grouse deļ¬ned by land cover, anthropogenic variables, soil, topography, and climate.
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 18-km search radius. Provides 18-km scale proportion of sagebrush land cover for use in examining multi-scale relationships.
Location of agriculture obtained from the LANDFIRE (90m) Existing Vegetation Type dataset
This map was developed to examine the distribution of edge denisty between sagebrush and all other landcover types. A map of sagebrush in the western United States was used as a base layer for a moving window analysis in FRAGSTATS to calculate edge density (km/sq km) within a 54-km search radius. Provides 54-km sagebrush edge density for examining landscape connctivity and spatial metrics.

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).

Powerlines in the western United States and Canada as identified by the 22 source data layers used to compile this shapefile. Source data were collected by personal contact or through the internet in the winter and spring of 2004 and assimilated using ArcGIS. This file is a complete record of overhead powerline data that was avaliable as of 5/15/2004 but IS NOT INTENDED TO BE A COMPLETE REPRESENTATION OF THE SUM TOTAL OF ALL POWERLINES ON THE GROUND. These data primarily depict the higher voltage, long distance transmission lines but some arcs likely represent lower voltage distribution lines.

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.

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...
