IUCN Category

The World Conservation Union (IUCN), widely considered to be the most objective and authoritative system for classifying species in terms of the risk of extinction^[1], lists 3071 species (1528 animals, 1541 plants, 2 fungi) of the world as being critically endangered in their 2006 Red List. Additionally 254 subspecies or varieties are considered critically endangered, and 30 subpopulations or stocks have been assessed with a critical risk of (local) extinction.
''Critically endangered'' is the highest risk category assigned by the IUCN for wild species. Critically endangered means that a species numbers have decreased, or will decrease, by 80% within three generations.^[2]
As the IUCN does not consider a species extinct until extensive, targeted surveys have been conducted, species which are possibly extinct are still listed as "Critically Endangered". A new category for "Possibly Extinct" has been suggested by BirdLife International to categorize these taxa.
