Conservation status

The conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future.

Many factors are taken into account when assessing the conservation status of a species: not simply the number remaining, but the overall increase or decrease in the population over time, breeding success rates, known threats, and so on.

UCN Red List of Threatened Species is the best-known worldwide conservation status listing and ranking system.

The system divides threatened species into three categories: Critically Endangered (CR), Endangered (EN), and Vulnerable (VU).
