IUCN Red List India Pdf Download –Endangered , Extinct Species India -The IUCN Red List of Threatened Species, founded in 1964, is the world’s most comprehensive inventory of the global conservation status of biological species.
- When discussing the IUCN Red List, the official term “threatened” is a grouping of three categories: Critically Endangered, Endangered, and Vulnerable.
- The pink pages in this publication include the critically endangered species. As the status of the species changes, new pages are sent to the subscribers.
- Green pages are used for those species that were formerly endangered, but have now recovered to a point where they are no longer threatened.
- With passing time, the number of pink pages continue to increase. There are pitifully few green pages.

- reduction in population (> 90% over the last 10 years),
- population size (number less than 50 mature individuals),

- it is therefore considered to be facing an extremely high risk of extinction in the wild.
- Endangered (EN) – High risk of extinction in the wild.
- Vulnerable (VU) – High risk of endangerment in the wild.
- Near threatened (NT) – Likely to become endangered in the near future.
- Least concern (LC) – Lowest risk. Does not qualify for a more at-risk category. Widespread and abundant taxa are included in this category.
- Data deficient (DD) – Not enough data to make an assessment of its risk of extinction.
- Not evaluated (NE) – Has not yet been evaluated against the criteria.
