The Map of Biodiversity Importance (MoBI) consists of a series of raster maps that combine habitat information for 2,216 imperiled species occurring in the conterminous United States, using weightings based on range size and degree of protection to identify areas of high importance for biodiversity conservation. Species included in the project are those which, as of September 2018, had a global conservation status of G1 (critical imperiled) or G2 (imperiled) or which are listed as threatened or endangered at the full species level under the United States Endangered Species Act. Taxonomic groups included in the project are vertebrates (birds, mammals, amphibians, reptiles, turtles, crocodilians, and freshwater and anadromous fishes), vascular plants, selected aquatic invertebrates (freshwater mussels and crayfish) and selected pollinators (bumblebees, butterflies, and skippers).<\/SPAN><\/SPAN><\/P>

This specific raster depicts summed range-size rarity for vertebrates, vascular plants, selected aquatic invertebrates (mussels and crayfish) and selected pollinators (bumblebees and butterflies and skippers) based on habitat data for 2216 species.<\/SPAN><\/SPAN><\/P>

NatureServe developed a habitat map for each species. Habitat maps for most species are model outputs generated using the random forest algorithm. Data inputs into the models include forty years of NatureServe Network element occurrence and observation data supplemented with records from USGS BISON and other sources and environmental predictors representing terrain, climate, land cover, soils, and hydrology. A national library of over 200 terrestrial and aquatic predictor variables supported the project. The resolution of modeling was 30m for most terrestrial species and 330m resolution for some wide-ranging species. Habitat models for aquatic species used a similar approach, but the medium resolution National Hydrography Dataset (NHD) was the modeling unit rather than a raster grid. If an existing, range-wide, and vetted model was easily obtainable for a species, we used that model instead of developing a new one. For species not amenable to inductive habitat modeling, we developed or obtained alternative habitat maps built using deductive approaches. We upscaled or otherwise converted habitat maps for all species to a 990-m raster to provide a consistent unit of measurement across species and avoid revealing the precise location of highly sensitive species. <\/SPAN><\/SPAN><\/P>

We calculated two values for each species using the habitat maps: range-size rarity and percent protected. Range-size rarity is the inverse of the total area mapped as habitat for the species and was calculated using the 990-m raster grid. Percent protected is the percentage of the total area mapped overlapping protected areas classified as Gap Status 1 or 2 in the PAD-US 2.0 database (USGS 2018; <\/SPAN><\/SPAN>https://www.sciencebase.gov/catalog/item/5b030c7ae4b0da30c1c1d6de<\/SPAN><\/SPAN><\/A> ) --i.e., those areas that are managed for biodiversity protection; it was calculated at the resolution of the source data.<\/SPAN><\/SPAN><\/P>

The MoBI dataset includes several different rasters: (1) Species richness rasters provide a simple count of the number of species with mapped habitat in each 990-m raster cell; higher values indicate where more imperiled species are likely to co-occur. (2) Range-size rarity (RSR) maps sum the range-size rarity scores of all species mapped as likely to occur in a cell; high values indicate the presence of habitat for one or more highly range-restricted species \u2013 i.e., concentrations of species with limited conservation opportunities. (3) Protection-weighted range-size rarity (PWRSR) rasters combine information on both range-size rarity and percent protected to identify locations with species that have limited conservation opportunities due to both restricted range size and falling outside of protected areas. Species-specific PWRSR scores are the product of range-size rarity and the percent of the range that is unprotected (1- percent protected). The MoBI dataset includes two versions of the PWRSR rasters: (3a) summed PWRSR, the sum of PWRSR values for all species with mapped habitat overlapping that cell, and (3b) maximum PWRSR, the highest PWRSR score for any species with mapped habitat overlapping the cell. To focus on the sites where protection action is most pressing, we clipped out the Gap 1 and Gap 2 protected areas from the protection-weighted range-size rarity maps. This particular raster represents (2) RSR for all species included in the MoBI project.<\/SPAN><\/P>

April 2021 Release Note: These data were updated with improved data. 33 species were added to the aggregate result that were previously erroneously excluded. In addition, a minor issue with how the original data were snapped was fixed, ensuring that all species within all of the MOBI layers are aligned consistently, regardless of the layers to which a given species contributes. Results may thus differ somewhat from the February 2020 release.<\/SPAN><\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "copyrightText": "NatureServe Network. April 2021. The Map of Biodiversity Importance.
