Question

Quizplus · Accepted Answer

The classification of a species as endangered is based on a variety of factors, not just population size. These factors include the rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. The International Union for Conservation of Nature (IUCN) and other organizations use criteria that consider these factors rather than a simple numerical threshold.
