Thus, endangered species is one category, whereas threatened species is a collective term to refer three IUCN categories. Species that are threatened are sometimes characterised by the population dynamics measure of critical depensation, a mathematical measure of biomass related to population growth rate.This quantitative metric is one method of evaluating the degree of endangerment. Destroying or changing habitats can endanger the animals, plants, and other organisms that live there. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals.
