Onager

The onager (Equus hemionus) is a species of the family Equidae (horse family) native to Asia.
The onager has a tawny, gray coat with a dark stripe running down its back. The lower portion of the limbs allow it to run swiftly across long distances. Mature males kick and bite their enemy rivals to occupy breeding territory. 
The greatest threat facing the onager is poaching for meat and hides, and in some areas for use in traditional medicine. It is the one of highest threats for the Mongolian wild ass. The extreme isolation of many subpopulations also threatens the species, as genetic problems can result from inbreeding. Overgrazing by livestock reduces food availability, and herders also reduce the availability of water at springs. The cutting down of nutritious shrubs and bushes exacerbates the problem. Furthermore, a series of drought years could have devastating effects on this beleaguered species.

Habitat loss and fragmentation are also major threats to the onager, a particular concern in Mongolia as a result of the increasingly dense network of roads, railway lines, and fences required to support mining activities.

The Asiatic wild ass is vulnerable to diseases, as well. A disease known as the "South African horse sickness" caused a major decline to the Indian wild ass population in the 1960s. Fortunately, the subspecies is no longer under threat to such disease and is continuously increasing their numbers.
