DEFINITION
|
|
EX
|
Extinct |
A species is Extinct when there is no reasonable
doubt that the last individual has died. |
|
EW
|
Extinct in the Wild |
A species is Extinct in the Wild when it
is known only to survive in cultivation, in captivity
or as a naturalized population (or populations) well out
side the past range. A species is presumed Extinct in
the Wild when exhaustive surveys in known and/or expected
habitat, at appropriate times (diurnal, seasonal, annual),
through out its historic range have failed to recover
an individual.
|
|
CR
|
Critically endangered |
A species is Critically Endangered (Critical)
when it is facing a very high risk of extinction in the
wild in the near future. |
|
EN
|
Endangered |
A species is Endangered when it is not Critical
but is facing a very high risk of extinction in the wild
in the near future. |
|
VU
|
Vulnerable |
A species is Vulnerable when it is not Critical
or Endangered but is facing a high risk of extinction
in the wild in the medium-term future. |
|
CD
|
Conservation Dependent |
Species which are the focus of a continuing
species-specific or habitat-specific conservation programme
targeted towards the species in question, the cessation
of which would result in the species qualifying for one
of the threatened categories above within a period of
five years. |
|
NT
|
Near Threatened |
Species which do not qualify for Conservation
Dependent, but which are close to qualifying for Vulnerable. |
|
LC
|
Least Concern |
Species which do not qualify for Conservation
Dependent or Near Dependent or Near Threatened. |
|
DD
|
Data Deficient |
A species is Data Deficient when there is
inadequate information to make a direct, or indirect,
assessment of its risk of extinction based on its range
and/or population status. A species on this category may
be well studied, and its biology well known, but appropriate
data on abundance and/or distribution is lacking. Listing
of species on this category indicates that more information
is required and acknowledges the possibility that future
research will show that threatened classification is appropriate.
However, it is important to make positive use of whatever
data are available. |

NE
|
Not Evaluated |
A taxon is not Evaluated when it has not
yet been assessed against the criteria. |
