About IUCN Red List of Threatened Species
- It was established in 1964, by the IUCN and has evolved to become the world’s most comprehensive information source on the global extinction risk status of animal, fungus and plant species.
- The IUCN Red List is a critical indicator of the health of the world’s biodiversity.
- It uses a set of quantitative criteria to evaluate the extinction risk of thousands of species.
- It provides information about range, population size, habitat and ecology, use and/or trade, threats, and conservation actions that will help inform necessary conservation decisions.
- It is used by government agencies, wildlife departments, conservation-related NGOs, natural resource planners, educational organisations, students, and the business community.
- The Index is available for five groups: birds, mammals, amphibians, corals and cycads.
