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: The failure of top-down environmental conservation practices gave rise to the so-called
`Community Based Conservation' or CBC approach. CBC promises to achieve the dual goals of
conserving nature and improving peoples' livelihoods. CBC programs also aim to involve local
communities as active partners in conservation efforts, and to use traditional knowledge and
local values in management of resources (Adams & Hulme 2001; Agrawal & Gibson 1999).
There are variations between different CBC programs; however, the underlying rationale of the
approach, common to all programs, is that introducing or changing economic incentives into the
conservation calculus of local people will bring about the behavioural change necessary for
successful conservation (Kellert et al 2000). Thus, the major emphasis in CBC programs is
conserving nature based on its utilitarian value. Since utilitarian value is measured in terms of
economics, hence the emphasis of CBCs on economic incentives in promoting conservation.
Recent evaluation of the CBC approach has shown that while local people may have benefited in
economic terms from the use of nature, no tangible improvements in biodiversity conservation
have occurred (Kellert et al 2000; Terborgh 1999). The disappointing performance of CBC
programs, which promised so much and yet have failed in practice to deliver, has recently lead to
a resurgence of the protectionist approach, calling for a renewed separation between the
conservation and human development objectives (Redford & Sanderson 2000; Terborgh 1999;
Oats 1999). Others, however, believe that the CBC approach has enormous potential, and that a
return to protectionist strategies would be disastrous, like `reinventing the square wheel'
(Brechin 2001; Wilhusen 2001). It is crucial that the flaws in the CBC approach are remedied if
there is to be any hope of a conservation agenda that does not conflict with the needs, aspirations
and interests of local people, and that therefore has a chance of having a long term, sustainable
conservation outcome.
