This map shows output from the UCSB statistical (Maxent) species distribution model for the Southwestern willow flycatcher,
Empidonax traillii extimus
.
The UCSB Maxent output includes both continuous and thresholded data. The binary layer depicting predicted suitable habitat was derived using the equal training sensitivity and specificity threshold.
Empidonax traillii extimus, Max Sensitivity + Specificity threshold = 0.1039; best AUC = 0.9866; mean AUC = 0.9796.
Based on examination of species observation data and consultation with biologists, CBI masked the model's broad extent output to within 10 km of the Colorado River and the following USFS ecoregion subsections: 322Aa, M261Er, M261Es, 322Ag, M262Bi, M262Bh, M262Bg, 322Cc.
