This map shows output from the UCSB statistical (Maxent) species distribution model for the Swainson's hawk,
Buteo swainsoni.
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.
For Buteo swainsoni, Max Sensitivity + Specificity threshold = 0.3028; best AUC = 0.9146; mean AUC = 0.9066.
Based on examination of species observation data and consultation with biologists, CBI used the model's narrow extent output masked to the following USFS ecoregion subsections: 322Ag, 322Aa, 322Cc.
Disclaimer: Species occurrence data shown on map are not a 100% complete representation of all locations of a given species.
