Endemicity

The total endemicity score is based on the presence of species unique to the region in the grid cell. It is one of the indicators in the World Bank’s open-access Terrestrial Biodiversity database, which was constructed by integrating comprehensive information from overlapping habitat maps of 6,532 amphibians, 5,435 mammals, 4,291 reptiles, and 11,126 birds. These authoritative habitat maps represent all known and catalogued species in each area from the International Union for Conservation of Nature and Birdlife International, as well as information on 827 distinctive ecoregions from the World Wildlife Fund (WWF) covering the entire terrestrial world. The database provides measures for each square kilometer of global territory
