| IUCN Red List Categories |
|
| The IUCN Red List is a catalogue of taxa that are facing the risk of extinction. The red list aims to impart information about the urgency and scale of conservation problems to the public and policy makers. The use of the Red List are |
| |
| i) Developing awareness about the importance of threatened bio diversity. |
| |
| ii) Identification and documentation of endangered species. |
| |
| iii) Providing a global index of the decline of biodiversity |
| |
| iv) Defining conservation priorities at the local level and guiding conservation action. |
| |
| The world conservation union (formerly IUCN) has recognised 8 Red List Categories of species. |
| |
| 1) Extinct |
| |
| 2) Extinct in the world |
| |
| 3) Critically endangered |
| |
| 4) Endangered |
| |
| 5) Vulnerable |
| |
| 6) Lower risk |
| |
| 7) Data deficient |
| |
| 8) Not evaluated |
| |
| The 2000 Red List contains assessments of more than 18,000 species, 11,000 of which are threatened. |
