IUCN Red List – Spatial Data Download

The IUCN Red List of Threatened Species™ contains global assessments for 105,732 species. More than 75% of these (81,323 species) have spatial data.

The spatial data provided below are for comprehensively assessed taxonomic groups and selected freshwater groups. It is important to note that some species (such as those listed as Data Deficient) are not mapped and subspecies, varieties and subpopulations are mapped within the parental species. The data are made available in Esri shapefile format and contain the known range of each species, although sometimes the range is incomplete. Ranges are depicted as polygons, except for the freshwater HydroBASIN tables. The shapefiles contain taxonomic information, distribution status, IUCN Red List Category, sources and other details about the maps (see metadata document).

Please note that the files are large and download times can be quite lengthy.

For ease of distribution and downloading, the data are divided by taxonomic groups. Groups that have been comprehensively assessed are those containing >80% species evaluated within the described taxon group.
