This dataset uses habitat suitability models to identify areas representing habitat conservation opportunities for a taxonomically diverse set of 2,216 of the nation's most imperiled species as listed below. Imperiled species are defined as species designated Globally Critically Imperiled (G1), Globally Imperiled (G2), or listed at the full species level on the Endangered Species Act. Higher scores are driven by the rarity (range size) of an imperiled species, the number of imperiled species co-occurring in a single grid cell, or a combination of both. Species include: -Vertebrates (birds, mammals, amphibians, reptiles, freshwater fishes; 309 species) -Freshwater invertebrates (mussels and crayfishes; 228 species) -Pollinators (bumblebees, butterflies, and skippers; 43 species) -Vascular plants (1,636 species) MoBI highlights the important relationship between species range size and habitat conservation opportunities. Within each Forest Service region, the grid cells with the highest (25%, 10%, 5%, and 1%) scores were identified.
