Note: New spatial data for the 2011 updates of the IUCN Red List of Threatened Species will be uploaded here in the next few weeks along with the implementation of some new spatial download features. In the interim, the spatial data made available here is for assessments that appeared on the 2010.4 update of the Red List. Please note that there may have been changes in the spatial data since that update and the maps may no longer match the distribution information provided on the species fact sheets on the Red List. In addition some of the species included in the spatial files below may no longer be on the Red List because of recent taxonomic changes.
The 2010 IUCN Red List of Threatened Species contained assessments for almost 60,000 species, of which about 28,000 had spatial data. This spatial data collection provided below is for most of the comprehensivley assessed taxonomic groups such as amphibians, mammals, threatened birds, reef-building corals, groupers, wrasses, angelfish, butterflyfish, seasnakes, seagrasses and mangroves. Spatial data is also provided for many of the reptile species that have been assessed. Other groups will be added to this collection once they are mapped. It is important to note that 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 (http://www.iucnredlist.org/technical-documents/assessment-process).
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). To limit the size of the shapefiles that are available to download, the higher taxonomy is not included in the data sets, only the genus and species name. The higher taxonomy including the current Red List Category information is available under each section, in excel format (these are the same data you would get if you ran a search on the Red List web site and exported the results as a CSV file), and you are able to join this file with the shapefiles when downloaded.
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.
While this data is made freely available to the public, please note that unfortunately we cannot provide technical support for use of the data in analyses or general GIS support.

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.
