उत्तर
Red Data Book or Red List is a catalogue of taxa facing the risk of extinction. IUCN (International Union for Conservation of Nature and Natural Resources), now renamed WCU (World Conservation Union, Morges, Switzerland), maintains the Red Data Book. The concept of the Red List was mooted in 1963.
The purpose of the preparation of the Red List is:
- To create awareness of the degree of threat to biodiversity.
- Identification and documentation of species at high risk of extinction.

- Extinct in the wild
- Critically Endangered
- Endangered
