Summary

This dataset consists of point features identifying indices for potential passage rate at intersections with major transportation corridors for grizzly bear movements between the Greater Yellowstone Ecosystem (GYE) and Northern Continental Divide Ecosystem (NCDE) in the northwestern United States. Points are spaced at 300-meter intervals along major road corridors (interstates and U.S. highways) and are populated with values from Randomized Shortest Path (RSP) predictive raster models of potential male grizzly bear movement between the two ecosystems as described in Peck et al. 2016 (Potential paths for male-mediated gene flow to and from an isolated grizzly bear population, Ecosphere 8(10):e01969). RSP scores extracted to point features [...]

Purpose

Randomized Shortest Path rasters were generated to delineate potential movement corridors of dispersal for male-mediated gene flow between grizzly bear populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE). Major roadways with high traffic volumes may restrict movement of bears and inhibit genetic exchange between the two populations. RSP scores intersecting major transportation routes provide spatially explicit information for land managers and organizations working with private land owners to identify and prioritize strategic locations for crossing structures (i.e., underpasses and overpasses) and other conservation measures that maintain or enhance the integrity of potential areas conducive to grizzly bear movement between ecosystems.
