Abstract:

This appendix focuses on the western rattlesnake (Crotalus oreganus) and describes the species’ distribution and habitat associations (such as for active seasons and wintering), movements/dispersal, and susceptibility to threats. This information is then used to model connectivity for rattlesnakes across the Columbia Plateau Ecoregion. The species was chosen because it is strongly associated with the shrubsteppe ecosystem that characterizes the Columbia Plateau, and its potential distribution spans the majority of the ecoregion, but its movement ecology leaves it susceptible to fragmentation. Results of modeling are discussed: resistance modeling, habitat modeling and habitat concentration areas, cost-weighted distance modeling, linkage modeling; maps illustrate. Key patterns and insights from the modeling analysis are listed. Linkage modeling can be useful for conservation planning of rattlesnakes, a species that may also represent other Columbia Plateau reptiles.
