This dataset represents the probability of occurrence for the noncarbonate alpine species assemblage within the Central Great Basin and Mohave Basin Ecoregion. This model represents the composite of multiple cross-validated inductive (Maximum Entropy) models of species distributions using non-spectral landscape variables. Input Variables: Elevation, geology, NatureServe's ecological systems map, distance to calcium carbonate soils, soil pH, slope, and aspect. Classification Model: 1 - High Potential Habitat NoData - Very Low Habitat Potential or "Non-Habitat"
