The 2009 IUCN Red List of Threatened Species contains assessments for 49,000 species of which spatial data exists for about 25,000 species, including all amphibians, mammals, threatened birds, and reef-building corals. Some species listed as Data Deficient are not mapped. These data are made freely available to the public to help inform conservation planning and other decision making processes. For more information about the assessment process, please see the IUCN Red List website (www.iucnredlist.org/).
The data are held in shapefiles, the ESRI native format and contain the known range of each species. Ranges are depicted as polygons. DBF files accompanying each polygon contain taxonomic information, and contain information on distribution status, sources and other details about the maps (see metadata document).
For ease of distribution and downloading the data is divided by taxonomic groups.
The data is available both in ESRI File Geodatabase format and the ESRI Shapefile format and is held in geographical coordinates. Please note that the files are large, and download times could be quite lengthy.
The ranges are available as a single data set (file Geodatabase) for all mammals or broken out into smaller data sets as shapefiles. The ranges are broken out by grouping families containing predominantly marine and terrestrial species.
The terrestrial file includes all mammals, excluding species in the families Otariidae, Phocidae and Odobenidae (i.e. all seals, sea lions and walrus), Balaenidae, Balaenopteridae, Delphinidae, Eschrichtidae, Iniidae, Monodontidae, Neobalaenidae, Phocoenidae, Physteridae, Platanistidae, and Ziphiidae (all whales, dolphins and porpoises), and everything in the Order Sirenia (manatees and dugongs). The latter families are included in the Marine shapefile.

The ranges are available as a single data set (File Geodatabase) for all Corals or broken out into smaller shapefiles by grouping families as follows:
Reef-building_corals_1 (zip file, 914 MB) contains species in the Order Scleractinia covering the families Acroporidae, Agariciidae, Astrocoeniidae, Caryophylliidae, Dendrophylliidae, Euphyllidae, and Faviidae.
Reef-building_Corals_2 (zip file, 532 MB) contains species in the Order Scleractinia covering the families Fungiidae, Meandrinidae, Merulinidae, Oculinidae, Mussidae, Oculinidae, Pectiniidae, Pocilloporidae, Poritidae, Rhizangiidae, and Siderastreidae.
Reef-building_Corals_3 (zip file, 27 MB) contains the species in the orders Stolonifera, Helioporacea and Milleporina covering the Families Helioporidae, Milleporidae, and Tubiporidae.
See metadata document for further information.
Threatened coral richness (number of species)
The ranges are available as a single data set for all (file Geodatabase) reptiles that have currently been assessed globally and comprehensively.
This currently includes, but is not limited to, all species endemic to the following regions: Canada, the United States and Mexico; the Seychelles; Europe; all of the Mediterranean (including North Africa), Caucasus, and Iran; and the Philippines. Further taxa will be added as assessment work is completed.
