living in a similar environment (Zheng et al.

Despite stemming from only 13 or 14 animals in zoo breeding programs, Przewalski's horses
have retained more genetic diversity than the domestic horse breeds the team examined.
China and Mongolia are the only two countries that have successively released Przewalski's horses
into the wild.
An earlier group of Przewalski horses was brought to the province six years ago from another location in Mongolia by Takh, a French association bearing the Mongolian name of Przewalski's horses
When they have their babies, they use abandoned domestic pastures to rear them,' says Denis Vishnevskiy, as he quietly watches a harem of seven wild Przewalski's horses

Primitive Przewalski's horses
are already being used to control woodland vegetation at Clocaenog Forest, while wild boar are being employed in private woods around Beddgelert.
Now, there are enough Przewalski's horses
to reintroduce herds into their native habitats.
Like many other rare animals, the small wild herds of Przewalski's horses
began to disappear.
Still in the planning stages is a fifth major exhibit, the Siberian Steppes, for the endangered Przewalski's horses
, the Siberian saiga, and other species from that region.
Since 1986, Chinese researchers have been cultivating a captive population of Przewalski's horses
, and the program has seen over twenty years of successful population expansion.
There are also the more rare argali (Ovis ammon) and reintroduced Przewalski's horses
(Equus przewalskii) released in the last several years.
