Abstract: An inverse relationship between individual vigilance level and group size is widely reported in many behavioral studies on animals across several taxa. It is generally held that such a relationship is due to a reduced probability of an individual being killed in larger groups. in the present investigation, I studied the vigilance behavior of the endangered Tibetan argali Ovis ammon hodgsoni in relation to group size and escape terrain. I hypothesized that an individual argali has a higher vigilance level in smaller groups and in habitats closer to cliffs than individuals living in larger groups and open areas (escape terrain). The results show that the vigilance of argali decreased with increasing group size, but there was no effect of escape terrain on its vigilance behavior. There were significant differences between age-sex groups: male, female and yearling in their time budgets. Females, compared to males and yearlings, spent more time being vigilant. They also foraged more and moved less than males. It is suggested that vigilance is an important anti-predator behavior amongst argali sheep.

Abstract: The distribution and status of large mammals was surveyed in a 15 000 km2 study area in Ladakh, India. Snow leopard Panthera uncia, wolf Canis lupus, ibex Capra ibex and bharal Pseudois nayaur have an almost continuous distribution throughout; Ladakh urial Ovis vignei, Tibetan argali Ovis ammon, wild ass Equus kiang and brown bear Ursus arctos have a limited distribution. Snow leopard prefer lower altitudes and rocky, undisturbed areas. Ibex and bharal occupy similar rocky habitats but their ranges are mostly separate, with a small area of overlap. The Ladakh urial shows signs of recovery from an earlier decline. Natural resources are widely used for fuel, fodder and grazing, but favourable factors include a low human population, low level of hunting and the existence of some uninhabited and undisturbed areas. A comprehensive Protected Area Network has been proposed.

Abstract: Solitary felids like tigers and snow leopards are notoriously difficult to enumerate, and indirect techniques like pugmark surveys often produce ambiguous information that is difficult to interpret because many factors influence marking behavior and frequency (Ahlborn & Jackson 1988). Considering the snow leopard's rugged habitat, it is not surprising then that information on its current status and occupied range is very limited. We adapted the camera-trapping techniques pioneered by Ullas Karanth and his associates for counting Bengal tigers to the census taking of snow leopards in the Rumbak watershed of the India's Hemis High Altitude National Park (HNP), located in Ladakh near Leh (76ø 50' to 77ø 45' East; 33ø 15' to 34ø 20'North).

Abstract: Reports on 1 summer survey and four winter surveys covering some 3100 km in Ladakh, India. Reports on snow leopard sign commonly found, distribution, prey, attacks on livestock and peoples reaction, mortality factors and conservation status. Suggest recomendations for preventing unnecessary killing of snow leopards and estimates population of 100 to 200 snow leopards in Ladakh

Abstract: Story of research trip looking for Tibetan Gazelle (Procapra picticaudata) in its last stronghold in India – Kalak Tar Tar (KTT) plateau in the Hanle area of hangthang – the great Tibetan high altitude plain that stretches at its extreme south-western and southeastern edges into India in Ladakh and Sikkim respectively. Species is known locally as “gowa”.

Abstract: Changes in economy and land use are under way in the Indian Transhimalayan region of Ladakh, creating both negative and positive prospects for wildlife conservation in this sparsely populations and previously remote area. New livestock breeds, irrigation developments, farming practices, foreign tourists, and a large military presence are changing the way people view and use the mountainous land that surrounds them. With only 0.3% of the land currently arable, changes in wildlife and natural resource conservation are most apparent on Ladakh's extensive rangelands which are apparently undergoing a redistribution of use associated with social changes and recently introduced animal husbandry and farming practices. International endangered species such as the snow leopard, several wild ungulates, and the black-necked crane provide special incentive for conservation efforts in what are some of the best remaining natural areas in the mountainous regions to the north of the Himalayan crest. The success of newly created protected areas for wildlife conservation in Ladakh rests on an understanding of the effects of various development directions, a commitment to environmentally sensitive development amid the many competing demands on Ladakh's natural resources, conservation laws appropriate to human needs, and a clear recognition that solutions can be neither directly adaptable from other mountainous areas nor even widely applicable across the Himalayan region.

Abstract: We had a good sighting of two adult and one sub adult lynx together, near Ganda-la
base which is at an elevation of 4900 meter, in Hemis National Park, Ladakh, during our fieldwork on Snow leopards in February 2004.The two adults lynx were moving closer and following each other, while the sub-adult lynx was a little far from the adults.
