Description
This map shows output from the UCSB statistical (Maxent) species distribution model for Flat-tailed horned lizard, Phrynosoma mcallii .

Based on examination of species observation data and consultation with biologists, CBI used the model's broad extent masked to the following USFS ecoregion subsections: 322Cd, 322Cc, 322Cb, 322Ca. The binary layer depicts predicted suitable habitat using the equal training sensitivity and specificity threshold (0.2456) and was processed by CBI to include the FTHL Borrego Badlands management area and to exclude areas outside of the species' historic range, based on data provided by Tony McKinny of US Fish and Wildlife Service.

The UCSB Maxent output includes both continuous and thresholded data. 

For Phrynosoma mcallii, Max Sensitivity + Specificity threshold = 0.2456; best AUC = 0.9314; mean AUC = 0.9286.
