The IUCN Red List of Threatened Species (also known as the IUCN Red List), is a rich compendium of information on threats, ecological requirements, and habitats of over 160,000 species; and on conservation actions that can be taken to reduce or prevent extinctions.
It is based on an objective system for assessing the risk of extinction of a species based on past, present, and projected threats. Species assessments are conducted following a standardised process using the rigorous IUCN Red List Categories and Criteria, ensuring the highest standards of scientific documentation, information management, expert review, and justification. IUCN aims to re-evaluate species’ IUCN Red List categories every five to ten years to monitor change.
The IUCN Red List is updated routinely throughout the year with submission target dates viewable here.
IUCN Red List data can be downloaded from IBAT at the global or sub-global level (<1 million km²). This download contains species’ ranges, species’ point data and a full species taxonomy for the latest IUCN Red List.
