Summary
Raster data depicting estimated jaguar energy expenditure required to move north from the US-Mexico border to reach important water sources. The data were generated for five scenarios: walled, un-walled crossing and three remediation scenarios: a border crossing through the wall in rugged terrain towards the west end of the wall, a crossing in a dry wash centrally located, one in less rugged terrain east of both.

The construction of a wall at the U.S.-Mexico border is known to impede and deter movement of terrestrial wildlife between the two countries. One such species is the jaguar, in its northernmost range in the borderlands of Arizona and Sonora. We developed an anisotropic cost distance model for jaguar in a binational crossing area of the Madrean Sky Islands at the U.S.-Mexico border in Southern Arizona using previously collected GPS tracking data for jaguars, bioenergetic calculations for pumas, and shuttle radar topography. This model describes projected energy expenditure for jaguar to reach key water sources, within a corridor, north of the international border.
