For example, after the Ice Ages, when the glaciers melted and the earth became warmer, many species died because they could not live in a warmer climate. When a species population declines by at least 20 percent within five years or two generations, it is also classified as endangered.4) Population restrictionsA species is classified as endangered when its population is restricted to less than 250 mature individuals. A species is also classified as endangered when its population has declined at least 50 percent and the cause of the decline is not known.2) Geographic rangeAn endangered species extent of occurrence is less than 5,000 square kilometers (1,930 square miles).
