Why it works

Catalyses action

The IUCN Red List is the starting point for conservation action. It shows where action needs to be taken to save species - the building blocks of nature - from extinction. It provides a straightforward way to factor biodiversity needs into decision-making processes by providing a wealth of useful information on species. 

Comprehensive

The IUCN Red List is a rich compendium of information on threats, ecological requirements, and habitats of 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 standardized process using the rigorous IUCN Red List Categories and Criteria, ensuring the highest standards of scientific documentation, information management, expert review, and justification.
