List of Important Critically Endangered Species

IUCN maintains a Red Data Book to classify species that are at high risk of global extinction. It divides species into nine categories: Not Evaluated, Data Deficient, Least Concern, Near Threatened, Vulnerable, Endangered, Critically Endangered, Extinct in the Wild and Extinct. The species classified as critically endangered are of importance as they require urgent steps for their preservation.

Before we go to the list of critically endangered species, let us first quickly revise about critically endangered category.

IUCN threat categories: Critically Endangered

• A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria given by IUCN, and it is therefore considered to be facing an extremely high risk of extinction in the wild.

Criteria

• Population size reduction of ≥90% over the last 10 years or three generations, whichever is the longer.
• Extent of occurrence estimated to be less than 100 km2, or area of occupancy estimated to be less than 10 km2.
• Population size estimated to number fewer than 250 mature individuals, and an estimated continuing decline of at least 25% within three years.
• Population size estimated to number fewer than 50 mature individuals
• Quantitative analysis showing the probability of extinction in the wild is at least 50% within 10 years or three generations.
