The new categories are based on less subjective cifteria than before and can be applied to populations as well as species.

EXTINCT (EX)

No reasonable doubt, from exhaustive surveys that the last individual has died.

Return

EXTINCT IN WILD (EW)

Surviving only in captivity or as a naturalised population well outside past range.

Return

CRITICALLY ENDANGERED (CR)

Extremely high risk of extinction in immediate future, e.g. 80% population decline, fragmented populations, habitat decline, <250 adults globally and failing, or <50 mature individuals.

Return

ENDANGERED (EN)

Very hight risk ofextinction in near future e.g. 50% population decline or severely fragmented population.

Return

VULNERABLE (VU)

High risk of extinction in medium term e.g. 20% observed or projected decline; range less than 100 Km

Return

LOWER RISK (LR) Three sub-categories:

• Conservation Dependent (cd)
  Cessation of conservation would move taxon into a threatened category within 5 years.
  
• Near Threatened (nt)
• Least Concern (lc)

Return

DATA DEFICIENT (DD)

Return

NOT EVALUATED (NE)
