The Przewalski’s horse Equus ferus przewalskii Groves, 1986 (PH) is considered to be the last and only remaining wild horse species in the world. However, it was extinct in the wild by 1969 and was reintroduced back into the wild in Mongolia, China and Kazakhstan in the 1990s. The species could survive in captivity after 53 foals from the Mongolian Gobi region were successfully shipped to European countries. However, only 12 of them produced foals. Reintroduction started only in 1992 by the import of 16 Przewalski´s horses from the Netherlands to Hustain nuruu in Mongolia in association with the Foundation for the Preservation and Protection of the Przewalski Horse and the Mongolian Association for Conservation of Nature and Environment. During 1992-2000 at five times 84 wild horses from European countries were reintroduced in Hustai National Park. At present 335 individuals of Przewalski’s horses exist in Hustai with 34 breeding harems and more than 80 bachelors compete for the mares. It is the highest number of Przewalski’s horse in the World.
