Abstract: The snow leopard has never been common, but there may be fewer than 4,000 left in its Himalayan habitat, and poaching and tourism-related development in the region could drive its numbers down further.

Abstract: As an important part of the ecosystem in the world, the wild are highly sensitive to impel the public to pay an increasing attention to the vertebrates and their habitats. The region from Xinjiang to Central Asian countries and from north China to Mongolia, explored less by zoologists. The region is mainly consisted of deserts and high mountain ranges many lakes and rivers that provide the suitable habitats for wildlife. These are actually unknown. Conservation in the modern sense is a very important part of development, especially in the Western Development of China. This paper deals with the species diversity and vertebrates' conservation in Xinjiang. Since 1980, over 20 Iocal nature reserves and 4 nationaI nature reserves have been established in Xinjiang. There are about 700 vertebrate species (in 5 classesœª37 ordersœr97 familiesœª196 genera) in Xinjiang. These cover about 134 species of mammalsœª392­® 430 species of birdsœr40­® 45 species of reptilesœª6­® 7 species of amphibians and 93­® 120 fishes. With the rapid economic development, some protected areas exist only in name. The areas are not only havens for wild species, but also maintain ecological benefits. Xinjiang is a very special region in China. The wild animals are different from those in other provinces along the east coast and in the interior. There are many questions about the conservation of wild animals in Xinjiang, e.g. the threatened species distinguishing, distribution and management, etc. So the paper is for reference only to the Great Development of Western China.

Abstract: The Ladakh urial (Ovis vignei vignei) is a highly endangered animal (IUCN Red List 2000) listed in the Appendix 1 of CITES and Schedule 1 of the Indian Wildlife Protection Act 1972. Its numbers had been reduced to a few hundred individuals in the 1960s and 70s through hunting for trophies and meat (Fox et al. 1991, Mallon 1983, Chundawat and Qureshi 1999, IUCN Red List 2000). However, with the protection bestowed by the IWPA 1972, and resultant decrease in hunting, the population seems to have shown a marginal increase to about 1000-1500 individuals in its range in Ladakh (Chundawat and Qureshi 1999, IUCN Red List 2000). Although the species had in the past, been able to coexist with the predominantly Buddhist society of Ladakh, the recent increase in the population of both humans and their livestock has placed immense pressures on its habitat (Shackleton 1997, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). This is especially important considering that the Ladakh urial habitat coincides with the areas of maximum human activity in terms of settlements, agriculture, pastoralism and development, in Ladakh (Fox et al. 1991, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). Increased developmental activities such as construction of roads, dams, and military bases in these areas have also increased the access to their habitat. This has consequently made the species more vulnerable to the threats of poaching and habitat destruction (Fox et al. 1991, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2002). Pressure from increased livestock grazing is one of the major threats faced by the species today (Shackleton 1997, Fox et al. 1991, Mallon 1983, IUCN Red List 2000 Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). In the impoverished habitat provided by the Trans-Himalayas, there is great competition for the scarce resources between various animal species surviving here (Fox 1996, Mishra 2001). The presence of livestock intensifies this competition and can either force the species out of its niche (competitive exclusion) by displacing it from that area or resource, or lead to partitioning of resources between the species, spatially or temporally, for coexistence (Begon et al. 1986, Gause 1934).
