During 1993~1997 , the status of Chinese wild ass was assessed. The Chinese wild ass is divided into two species , i. e. Mongolian wild ass or chigetai , kulan ( Equus hemionus) and Tibetan wild ass or kiang ( Equus kiang) . Equus hemionus is distributed in the Meng-Xin Region , while Equus kiang was found in the Qin- Zang Region , including Inner Mongolia , Xinjiang , Tibet , Qinghai , Gansu and Sichuan Province. The distribution area of Mongolian wild ass is about 0. 14 million km2 (40°20′~46°40′N ,85°40′~107°30′E) , about 700~1500 m in altitude , with a population size less than 2000. Tibetan wild ass is distributed in an area of about 0. 972 507 million km2 (27°48′~39°27′N ,78°40′~103°00′E) ,about 3000~5500 m in altitude , with an estimated population size of 88 871.
