Description: This map shows output from the USGS statistical (Maxent) species distribution model for Desert Tortoise, Gopherus agassizii .

The species distribution model output includes both continuous and thresholded data.The binary layer depicts predicted suitable habitat using the equal training sensitivity and specificity threshold (0.506). The binary output was also processed by CBI to exclude agriculture, developed, and disturbed areas, based on the DRECP land cover/natural vegetation dataset provided by Todd Keeler-Wolf of the CA Dept. of Fish and Game.

Disclaimer: Species occurrence data shown on map are not a 100% complete representation of all locations of a given species.
