A species is listed as “endangered” if it has lost 70 per cent of its population in the last ten years.
It is critically endangered if 90 per cent has been lost or 80 per cent with the causes still ongoing.
The peregrine falcon became the first animal listed as an endangered species in the USA in the late 1970’s.
By 1996 the United States Fish and Wildlife Service had compiled a list of more than 1,400 species of endangered or threatened animals and plants (of which more than 500 are found only in foreign countries), and some 200 recovery programs were in effect.
According to a 2004 report by the World Conservation Union, 15,589 species are now considered at risk of extinction.
The black rhino, white rhino, Sumatran rhino and Javan rhino are all listed as critically endangered species by the World Wildlife Fund. There are fewer than 100 Sumatran rhinos left in the world and
only about 60 Javan rhinos.
