Species models are ResUNet-34 convolutional neural networks, trained per USGS region against GAP species habitat maps and aligned to a 30m grid across CONUS. Predictions are converted to state and national percentiles so the map reads as a ranking, not a raw score.
• LANDFIRE Existing Vegetation Type, Cover, and Height (EVT / EVC / EVH)
• LANDFIRE 30m Digital Elevation Model (elevation, with derived slope and aspect)
• NLCD Impervious Surface Descriptor (road proximity)
• USGS GAP Species Habitat Maps (training labels)
• PADUS (public-land boundaries, map overlay)
