Red List Spatial Data

The IUCN Red List of Threatened Species contains assessments for just over 76,000 species, of which about two-thirds have spatial data. This spatial data provided below is for comprehensively assessed taxonomic groups. It is important to note that some species such as those listed as Data Deficient are not mapped and subspecies are mapped within the parental species. The data is available as ESRI shapefiles format and contains the known range of each species. Ranges are depicted as polygons. DBF files accompanying 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 could be quite lengthy. Please be aware that not all species have spatial data due to Data Deficient species not being consistently mapped and subspecies beginning included within parental species polygons.

For ease of distribution and downloading, the data is divided by taxonomic groups.

The data is made freely available to the public for non-commercial use, to help inform conservation planning and other decision making processes (see Terms and Conditions of Use). For more information about the assessment process, see Red List Assessment Process. Please note that unfortunately we cannot provide technical support for use of the data in analyses or general GIS support.

For all enquiries about spatial data, please contact the IUCN Red List GIS Unit.

Note: A species richness page will be available shortly.
