Project view - Animals in Danger of Extinction


Project text:

There are currently 2129 animals and 1821 plants with this assessment, compared with 1998 levels of 854 and 909, respectively. Thatś why we have chosen only five, which we considered to be very interesting for us. We would like to explain what it means if animals are in danger of extinction.

To be defined as critically endangered in the Red List, a species must meet ANY of the following criteria (A–E) ("3G/10Y" signifies three generations or ten years—whichever is longer—over a maximum of 100 years; "MI" signifies Mature Individuals):

A: Occurring over less than 100 km² and two of:
1. Severe habitat fragmentation or existing at just one location
2. Decline in extent of occurrence, area of occupancy, area/extent/quality of habitat, number of locations/subpopulations, or amount of MI.
3. Extreme fluctuations in extent of occurrence, area of occupancy, number of locations/subpopulations, or amount of MI.
B: As above, but less than 10 km² (used to show differing levels of severity).
C: Declining population of less than 250 MI and either:
1. A decline of 25% over 1G/3Y;
2. Extreme fluctuations, or over 90% of MI in a single subpopulation, or no more than 50 MI in any one subpopulation.
D: Numbers less than 50 MI.
E: At least 50% chance of going Extinct in the Wild over 3G/10Y.

The project contains these units:
