Critically Endangered Animal Species of India

Among the classification of threatened species, the category Critically Endangered corresponds to the greatest risk. In India, there are 70+ critically endangered animals and 60+ critically endangered plants. 300+ animals fall under the category of endangered while 140+ plants fall under the category of endangered.  This post is a detailed list of the critically endangered animal species in India.

When is a species considered critically endangered?

Critically endangered is the highest risk category assigned by the IUCN (International  Union for Conservation of Nature) Red List to wild species. There are five quantitative criteria to determine whether a taxon is threatened. A taxon is critically endangered when the best available evidence indicates that it meets any of the following criteria:

  1. Populations have declined or will decrease, by greater than 80% over the last 10 years or three generations.
  2. Have a restricted geographical range.
  3. Small population size of less than 250 individuals and continuing decline at 25% in 3 years or one generation.
  4. Very small or restricted population of fewer than 50 mature individuals.
  5. High probability of extinction in the wild.
