The Mongolian khulan, also known as the Mongolian Wild Ass (Equus hemionus hemionus) is one of the 5 recognized sub-species of the Asiatic Wild Ass and currently does represent the largest population of the Asiatic Wild Ass in the world. The Mongolian Khulan mainly live in south of Mongolia in the Gobi desert area, with small populations in north of China. Mongolia represents a very important place for conservation of the Asiatic Wild Ass.


The Asiatic Wild Ass belongs to the Equids, like horses, donkeys, zebras, Przewalski's horses, African Wild Ass, but is a species on its own. 

Its habitat has decreased over the past years ...

The former range of the Asiatic wild ass between the seventeenth and the middle of the nineteenth century encompassed the greater part of Mongolia, small areas of Siberia and Manchuria, the western part of Inner Mongolia and the northern part of Xinjiang. Southern Mongolia currently holds the largest population of Asiatic wild ass in the world, representing almost 80% of the global population (Feh et al. 2002).  Therefore, Mongolia is a very important stronghold of the Mongolian wild ass.


The population of the Mongolian khulan (Equus hemionus hemionus) was estimated in 1997 at about 43,165 individuals (Feh et al. 2001, Reading et al. 2001). Numbers have declined significantly to be later estimated in 2003 at 18,411 +/- 898 in four areas (Lkhagvasuren 2007). Recently, the population has been estimated to about 40,000 individuals, meaning that the population seems to be now stable.  However, this population is at risk due to illegal hunting and fragmentation of its habitat due to an increasing mining activity in the Gobi Desert. 


In the Gobi, 99% of the habitat is used as livestock pasture. In such The Mongolian khulan (Equus hemionus hemionus) was estimated in 1997 at about 43,165 individuals (Feh et al. 2001, Reading et al. 2001). Numbers have declined significantly to be later estimated in 2003 at 18,411 +/- 898 in four areas (Lkhagvasuren 2007). Recently, the habitats long-distance transhumance is a necessity for sustainable pastoralism. Thus, semi-nomadic herders need access to large tracts of land, including protected areas. Moreover, political changes in the early 1990’s forced urban populations to return to nomadic land use, resulting in a sharp increase in human and livestock numbers in many rural areas.


Water in the Gobi desert area is a critical resource for humans, livestock production and influence wildlife habitat, but is very rare and very scarce. In such area, access to water appears to be one key for the conservation of wild Equids, and if access to water can be secured it can ensures optimal nutritional care of their offspring without huge energy demands on the mother pre and post partum.


Most water for human and livestock must be obtained from small and hand drawn wells. Numerous mechanical wells were built during the collective era, but most of them have fallen into disrepair since 1990. Because of this lack of wells, herders and their livestock are forced to use open water points also used by wildlife. Khulan do not avoid wells or human settlements, but they preferentially drink at open water points or digging potholes they made in dry river beds or dry water points (Kaczensky et al., 2006, and Anne-Camille Souris, observations made in 2008 and 2009). Wells allow human presence in areas where there is little surface of water. But if there is an open water source nearby, then, herders will preferentially use it compare to wells.


Mongolia’s rural economy is mostly based on livestock, thus wild ungulates have to co-exist with semi-nomadic pastoralists.

A species directly and undirectly threatened by humans

The status of the Mongolian khulan has been downlisted from "endangered" to "near threatened" in 2015, however its population is still at risk due to many threats that are still affecting this species's survival.

The Mongolian khulan, a Gobi ecosystem engineer species

The Mongolian khulan is locally known for its ability to dig holes at dry water points and river beds to access to underground water, then creating some kind of "wells" or "watering holes" from which they can drink. This very specific behavior is mostly observed during the dry periods of the year where in the Gobi Desert replenishment of water points depends on rainfall. In order to adapt to the dry periods and the lack of open water points and sources in the Gobi Desert, the Mongolian khulan has adapted and developped this very specific behavior and dig holes of different sizes and depth to access to water.
