The Map of Biodiversity Importance (MoBI) identifies areas of high importance for species conservation in the contiguous United States. Building on habitat suitability models for 2,216 of the nation’s most imperiled species, and information on range size and degree of protection derived from those models, the MoBI project provides a series of maps that can help inform conservation efforts. This map depicts richness of Critically Imperiled (categorized by <a href="http://natureserve.org/">NatureServe</a> as “G1”), Imperiled (“G2”), and ESA-listed (i.e., full species listed as Endangered or Threatened under the Endangered Species Act) species in the taxonomic group specified in the layer name. High values identify areas where more imperiled species are most likely to occur. Habitat models for most species were generated using the random forest algorithm with (1) NatureServe Network, <a href="https://bison.usgs.gov/">USGS BISON</a>, and other sources of population and locality data and (2) environmental predictors representing terrain, climate, land cover, soils, and hydrology. The modeling resolution for terrestrial species was either 30 m (most species) or 330 m (some wide-ranging species). Models for aquatic species used the medium resolution <a href="https://www.usgs.gov/core-science-systems/ngp/national-hydrography">National Hydrography Dataset (NHD)</a> as the modeling unit. For species not amenable to random forest modeling, habitat maps were derived by buffering locality data and/or building simple deductive models based on habitat information. NatureServe converted habitat maps to a 990-m raster to provide a consistent unit of aggregation and avoid revealing the precise location of sensitive species. Richness values are simply a tally of the number of species with habitat overlapping a cell.
