Abstract: The Asiatic wild ass Equus hemionus, or khulan, once ranged across much of Central Asia, but is now globally threatened. The largest free-ranging populations are now restricted to a 250-km wide area (range 100ñ400 km) across the Gobi Desert region of southern Mongolia. Over the last 23 years the population has moved further north and east into its former range. Surveys conducted in the 1970s and 1980s estimated that the Mongolian population contained fewer than 15 000 animals and was declining as a result of human exploitation and livestock competition. Aerial surveys (one in autumn 1994, two in spring 1997) were flown as line transects over portions of the khulan's range in Mongolia and ground surveys (’ve in spring, summer, and autumn 1994ñ97) were conducted by vehicle and foot. Sample sizes and areas surveyed were larger than previous surveys, and our methods were often more systematic. Population size was estimated at 33 000ñ63 000 wild asses in Mongolia. Animal density ranged from 4.2 a 1.3 to 19.1a 3.2 per 100 km2. Mean group size ranged from four to 35 animals in the south-western Gobi, four to seven animals in the southern Gobi, and three to 18 in the south-eastern Gobi. Our data suggest that Mongolia is the most important stronghold for the conservation of E. hemionus. Conservation management continues to be challenging because intensive studies on khulan biology and ecology are just beginning. As a freemarket economy continues to emerge in Mongolia, pressure from resource extraction interests and nomadic livestock herders to remove the khulan's protected status, permit harvesting and halt population growth and expansion, also makes implementation of research and conservation management programs more imperative.

Abstract: Claims poaching and competition with domestic livestock are threatening the argali's survival in Mongolia. The author's conducted aerial and ground surveys in the South Gobi and estimated a populaton size of approximately 3,900 argali.

Abstract: In the International Pedigree Book of Snow Leopards 3, Blomqvist and Sten notes (1982) that no information had been recieved on the snow leopard in Mongolia. The present paper sets out to repair that omission by summarising the information in print on snow leopards in Mongolia and giving a brief account of its distribution in the country. This is essentially a review paper and it is hoped that more precise data may be obtained from fieldwork carried out in the future by Mongolian zoologist. The author worked in Mongolia for two years 1975-1977, and during that time collected information on mammals of Mongolia. Information on the snow leopard was obtained from colleagues at the State University of Mongolia; from zoologists and hunters; from herdsmen and local informants from all parts of the country and from three journeys made by the author: to the eastern Gobi Altai; the Khangai mountains, and a 2000 km journey through western Altai. In this paper, the term “Mongolia” refers to the territory of the Mongolian peoples Republic

Abstract: In the Mongolian and Gobi Altai mountain ranges and also in some other mountains in this region, the
distribution of the snow leopard and Eurasian lynx overlaps. In some cases, local hunters cannot
distinguish the tracks of both these animals. Therefore we outline a simple method to distinguish tracks of
the snow leopard and lynx.
