Within this site you will find maps of biodiversity across our world. Global maps currently available include terrestrial vertebrates and marine cone snails and are based on species range maps from the IUCN (mammals, amphibians, and cone snails) and BirdLife International and NatureServe (birds). For the USA, there are maps of all terrestrial vertebrates, freshwater fish, and trees, as well as a map of conservation prioroties for the country.
GIS-ready datasets are available on the Download page.
Methods used in preparing the biodiversity maps can be found here.
