The World Conservation Union's Red List of Threatened Species listed the Przewalski's horse as extinct in the wild until 2008. Causes of extinction were hunting, harsh climate, loss of habitat, and loss of water sources to farm animals. However, successful reintroductuions qualified this species for reassessment in 2008, and they are now classified as critically endangered. Currently, there are around 1,500 animals remaining in zoos and breeding facilities, carrying genes from 14 founders. Because loss of genetic diversity threatens their continued survival, the National Zoo's Conservation and Research Center and other institutions around the world maintain breeding populations that serve as a source of animals for reintroduction in Mongolia, China, and Kazakhstan. Thanks to their effort nearly 400 horses now roam in re-introduction sites in Mongolia and China.
