EXTINCT (EX)
A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed
Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal,
annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame
appropriate to the taxon's life cycle and life form.
EXTINCT IN THE WILD (EW)
A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized
population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when
exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual),
throughout its historic range have failed to record an individual. Surveys should be over a time frame
appropriate to the taxon's life cycle and life form.
CRITICALLY ENDANGERED (CR)
A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A
to E for Critically Endangered (see Section V), and it is therefore considered to be facing an extremely high
risk of extinction in the wild.
ENDANGERED (EN)
A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for
Endangered (see Section V), and it is therefore considered to be facing a very high risk of extinction in the
wild.
VULNERABLE (VU)
A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for
Vulnerable (see Section V), and it is therefore considered to be facing a high risk of extinction in the wild.
NEAR THREATENED (NT)
A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically
Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened
category in the near future.
LEAST CONCERN (LC)
A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically
Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in
this category.
DATA DEFICIENT (DD)
A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its
risk of extinction based on its distribution and/or population status. A taxon in this category may be well
studied, and its biology well known, but appropriate data on abundance and/or distribution are lacking. Data
Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is
