The Mongolian Government declared Hustai National Park as a Specially Protected Area in 1993, one year after the initiation of the reintroduction of the last species of wild horse project. This national park is the best place to see 100% wild horses called takhi in Mongolian. The Wild horse became extinct in the wild and was last seen in the Gobi in the late 1960s. It survived only in zoos and private parks around the world. The reintroduction program began in 1992.
Horses were selected for maximum genetic diversity and gathered at semi-reserves in the Netherlands. Over a two year period, they formed socially normal herds, each consisting of a stallion and his harem of mares. Then they were flown to Mongolia from Luxembourg airport. In addition to the takhi, there are populations of marmots, steppe gazelle, deer, boar, small wild cat, wolves and lynx. The other mammal species need some patience and are more likely to be seen while hiking on foot around the reserve.
