This dataset contains measures of natural vegetation fragmentation for the Colorado Plateau Ecoregion calculated using FRAGSTATS, a program which produces a series of metrics that are focused on fragmentation at the individual patch, class, and landscape levels. The fragmentation surface (input to FRAGSTATS) was created from NLCD Impervious Surfaces, LANDFIRE EVT, NatureServe National Landcover, roads, utility lines, power plants, pipelines, geothermal wells, mines, wind turbines, and oil/gas wells.The following three fragmentation metrics generated by FRAGSTATS (contained in this dataset) were chosen as input variables to the terrestrial landscape intactness logic model:1.) Number of patches [NP attribute] 2.)...

The landscape permeability model represents the structural connectivity of sagebrush ecosystem habitat in the Green River Basin (including ~5-10 km boundary outside of the GRB. This model connects patches of habitat, across the landscape using resistances that represent the degree of human modification and slope (energetic costs), using the Multi-Scale Landscape Permeability model (Theobald et al. 2012; Theobald unpublished). We used two metrics: (a) patch importance and (b) betweeness centrality amongst patches. These metrics were summarized for each HUC12. This dataset represents the vulnerability of sagebrush ecosystem permeability to human modification summarized for each HUC12 watershed within the Green River...
