How Many Endangered Species Are There

There are about 50,000 species that are on the IUCN Red List. Some of these are the Loggerhead Turtles, Siberian Tiger, Mountain Gorilla and the Blue Whale. 16,306 of them are endangered species threatened with extinction. This is up from 16,118 last year. This includes both endangered animals and endangered plants.

The species endangered include one in four mammals, one in eight birds, one third of all amphibians and 70% of the world’s assessed plants on the 2007 IUCN Red List are in jeopardy of extinction. The total number of extinct species has reached 785 and a further 65 are only found in captivity or in cultivation. In the last 500 years, human activity has forced over 800 species into extinction.

In 2010, a total of 47,978 species were evaluated, so let’s break it down a little further. Most mammal, bird and amphibian species were completely or almost completely evaluated. According to the results, birds are doing the best: only 12 percent of them are vulnerable, endangered or critically endangered. Mammals come in next at 21 percent. Amphibians are struggling the most: 30 percent are in trouble.

How many endangered species are there in the US?

There are about 400 animals in the United States who are listed as endangered, and about 130 that are threatened. Worldwide, there are about 500 animals listed as endangered and 39 listed as threatened.

IUCN Red List refers to a specific category of threatened species, and may include critically endangered species. The IUCN Red List uses the term endangered species as a specific category of imperilment, rather than as a general term. Under the IUCN Categories and Criteria, endangered species is between critically endangered and vulnerable. Also critically endangered species may also be counted as endangered species and fill all the criteria

The more general term used by the IUCN for species at risk of extinction is threatened species, which also includes the less-at-risk category of vulnerable species together with endangered and critically endangered.
