IUCN Red List

---

The IUCN Red List of Threatened Species (http://www.iucnredlist.org/) is considered to be the world’s most comprehensive repository of information pertaining to the conservation status of the world’s species. The IUCN Red List uses the IUCN Red List Categories and Criteria as a standard methodological approach to assessing the risk of extinction of the planet’s biodiversity based on information relating to the distribution, population status, ecology and natural history, threats and conservation actions known for species being assessed.

Amphibians are a prominent part of the IUCN Red List, comprising one of three vertebrate groups (together with birds and mammals) to have been comprehensively assessed at least once. This comprehensive assessment was done by the Global Amphibian Assessment (GAA) initiative in 2004, and there have been smaller updates since then, concentrating primarily on the addition of new species and some smaller regional/national updates. However, Red List assessments need to be updated within a period of ten years if they are not to become obsolete. Reassessing previous assessments is a more involved process than assessing brand new species, and need a new approach, which is why we have a new tool: The Amphibian Red List Assessment Forum.

IMPORTANT NOTE: Given the current quality control requirements needed for conservation assessments to be published on the IUCN Red List, and our very limited human resources, we are unable to process large numbers of assessments at this time. Country-level global reassessments may be possible if requests come with the funding and resources necessary to conduct such reassessments, or if the herpetological community of the country or region in question is willing to take over stewardship of its global assessments through its respective regional/national working group.
