Population size fewer than 250 mature individuals

- This criterion is not used for classifying a species as Vulnerable because it falls under the category of Critically Endangered.
- The IUCN Red List classifies species with a population size fewer than 250 mature individuals as Critically Endangered, which is a higher level of threat compared to Vulnerable.
- The criteria for Vulnerable species include a population size fewer than 10,000 mature individuals, a reduction in population size of more than 50% over the last 10 years, and a probability of extinction in the wild of at least 10% within 100 years.
- Species that meet these criteria are considered Vulnerable, indicating that they are facing a high risk of extinction in the wild in the near future.
- The population size fewer than 250 mature individuals is a more severe condition and warrants classification as Critically Endangered, where the species is at an even higher risk of extinction.
