Conditions for Species considered critically endangered:
- Occurring over less than 100 km²: Existing at just one location, Decline in occurrence, area of occupancy, area/extent/quality of habitat, number of locations/subpopulations, Extreme fluctuations in extent of occurrence, area of occupancy.
- As above, but less than 10 km² (used to show differing levels of severity).
- Declining population of less than 250 Matured individuals and either:A decline of 25% over 3-Generation/10Year whichever is longer and Extreme fluctuations.
- Numbers less than 50 Matured individuals.
- At least 50% chance of going Extinct in the Wild over 3-Generation/10Year whichever is longer.
