Connectivity for Climate Change in the Southeastern United States
In partnership with South Atlantic LCC members, we assessed current and projected connectivity for three species (black bear [Ursus americanus], Rafinesque’s big-eared bat [Corynorhinus rafinesquii], timber rattlesnake [Crotalus horridus]) that inhabit bottomland hardwoods throughout the southeastern US. For each species, we mapped important habitat connections between core patches of habitat using three different modeling approaches (Connectivity Analysis Toolkit (CAT), Circuitscape, and Linkage Mapper) that incorporated three types of resistance layers (expert opinion, niche modeling, and empirical data for the black bear only). The result was 21 sets of important connections, one for each of the species-resistance-connectivity algorithm combinations we analyzed. In this data set, we present the results of overlaying all of the connections in the 21 sets of results on current climate suitability, as well as future climate suitability. The data here show the change in suitability under climate change for all connections mapped in our study.
