Created: Saturday, 16 December 2017

These are the categories used in the Austrian Red Lists

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.

REGIONALLY EXTINCT (RE)
A taxon is Regionally Extinct when there is no reasonable doubt that the last individual in that geographical region has disappeared or died. or, in the case of an earlier guest taxon, individuals no longer visit that geographical region.

CRITICALLY ENDANGERED (CR)
50% extinction probability in 10 years or 3 generations (maximum 100 years).

ENDANGERED (EN)
20% extinction probability in 20 years or 5 generations (maximum 100 years).

VULNERABLE (VU)
10% extinction probability in 100 years.

NEAR THREATENED (NT)
Less than 10% extinction probability in 100 years, but negative stock development and high extinction risk in parts of the area.

LEAST CONCERN (LC)
Less than 10% extinction probability in 100 years, other attributes as under NT are not valid.

DATA DEFICIENT (DD)
The available data does not allow a classification into the individual categories.
