Spatial Data & Mapping Resources

Spatial Data Download

The IUCN Red List of Threatened Species contains global assessments for almost 134,400 species. More than 82% of these (>111,000 species) have spatial data.

The spatial data provided below are mostly 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 three formats, including taxonomic information, distribution status, IUCN Red List Category, sources and other details about the maps (see metadata document):

  1. Polygons in Esri shapefile format, containing the known range of each species. Note that sometimes the range is incomplete.

  2. Points as a csv (comma separated value) table including the latitude and longitude of each observation.

  3. Freshwater HydroBASIN Tables in csv format. Freshwater species are mapped to pre-defined river/lake catchment units called HydroBASINS. It is widely accepted that the river/lake catchment is the most appropriate management unit for inland waters. These species range tables contain the HydroBASIN ID field which can be joined to the HydroBASINs spatial data. 

Please note: Some of the files are large and download times can be quite lengthy. The largest hydrobasin tables (Fishes, Molluscs, Odonata and Plants) have more rows than can be viewed in common spreadsheet applications such as Excel or LibreOffice Calc.

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.

The data are made freely available for non-commercial use, to help inform conservation planning and other non-commercial decision-making processes (see Terms and Conditions of Use).

For commercial use of the data, visit the Integrated Biodiversity Assessment Tool (IBAT) website.

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.
