Each time The IUCN Red List is updated, the Spatial Data Download page (in the Resources and Publications section) is also updated to provide all the current map data for various groups of species (including polygon spatial data and point data, where available).
Red List Guidelines
Version 14 of the Guidelines for Using the IUCN Red List Categories and Criteria was released in English in August 2019. This document is now available in both French and Spanish, bringing all three language versions up to date.
Extinction Risk Assessment tools
The Extinction Risk Assessment tools page in the Resources & Publications section provides access to the Threats model and the Records and Surveys model to help Assessors determine the probability of a species now being Extinct or Extinct in the Wild. These tools are now also available in French and Spanish.
