Raster digital data sets identifying a range-wide network of priority areas for greater sage-grouse The delineation of priority areas in western North America for managing Greater Sage-Grouse (Centrocercus urophasianus) represents a broad-scale experiment in conservation biology. The strategy of limiting spatial disturbance and focusing conservation actions within delineated areas may benefit the greatest proportion of Greater Sage-Grouse. However, land use under normal restrictions outside priority areas potentially limits dispersal and gene flow, which can isolate priority areas and lead to spatially disjunct populations. We used graph theory, representing priority areas as spatially distributed nodes interconnected by movement corridors, to understand the capacity of priority areas to function as connected...

We assumed that individual sage-grouse would move more easily through areas meeting their habitat requirements and used a scaled inverse of our mapped habitat scores as resistance to sage-grouse movements among the priority areas. Resistance values ranged from 1 representing the lowest resistance/highest habitat value to 100 (high resistance/lowest habitat value). Circuitscape (McRae et al. 2008) was run using the pairwise mode to calculate connectivity between all pairs of priority areas. Priority areas were treated as focal...
