Summary
These data are statistical model outputs for Swainson's hawk (Buteo swainsoni ) species distribution, completed by Frank Davisâ Biogeography Lab at UC Santa Barbara. 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. The UCSB Biogeography Lab used Maxent to generate predictions of habitat occupancy for ~70 species for the CA Energy Commissionâs project âCumulative Biological Impacts Framework for Solar Energy in the CA Desertâ, 500-10-021. Species distribution models were produced at 270 m resolution using a subset of 22 environmental variables. Models were evaluated with 10-fold [...]
Summary
These data are statistical model outputs for Swainson's hawk (
Buteo swainsoni ) species distribution, completed by Frank Davisâ Biogeography Lab at UC Santa Barbara. 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.Â
The UCSB Biogeography Lab used Maxent to generate predictions of habitat occupancy for ~70 species for the CA Energy Commissionâs project âCumulative Biological Impacts Framework for Solar Energy in the CA Desertâ, 500-10-021.
Species distribution models were produced at 270 m resolution using a subset of 22 environmental variables. Models were evaluated with 10-fold cross validated AUC scores.Â
Both continuous probability surfaces and binary layers are available for each species modeled. Binary layers depicting predicted suitable habitat were derived using the equal training sensitivity and specificity threshold.Â
For
Buteo swainsoni, Max Sensitivity + Specificity threshold = 0.3028; best AUC = 0.9146; mean AUC = 0.9066.Â
