    Ranging and Habitat Utilization by the Himalayan Ibex (Capra ibex sibirica) in Pin Valley National Park.
    (Wildlife Institute of India, Dehradun, 1997) Bhatnagar, Yashveer; Rawat, G.S.
    The Himalayan ibex is an important prey species of the endangered apex predator of the alpine region, the snow leopard (Schaller 1977). There is an imminent threat to the trans-Himalayan areas in India due to increasing human activities. In this context the study is conducted to study ibex in a relatively safe population to learn about its habitat requirements and ranging behaviour. The study area is part of the Pin Valley National Park (PVNP; 31o 6' 40'' to 32o 2' 20'' N latitude and 77o 41' 21" to 78o 6' 19" E longitude), located in the South-East of the Lahul and Spiti district of Himachal Pradesh

    Feeding Ecology of Ibex (Capra ibex sibirica) in Pin Valley National Park, Himachal Pradesh.
    (Wildlife Institute of India, Dehradun, 1997) Manjrekar, Neema; Johnsingh, A.J.T.
    The foraging ecology of the Asiatic ibex was studied in Pin Valley National Park Lahul and Spiti District, Himachal Pradesh, between October 1991 and October 1994. The National Park encompasses 675 km2, and has a buffer of 1150 km2. The study area constituted part of the Parahio catchment of the pin Valley. Thango was the base camp for this study. It was a summer settlement of five families from Sagnam, the largest village of Pin Valley. The local people are Buddhists, of Tibetan origin. Apart from cultivating the land adjacent to the villages, in the buffer zone, they use the Park area for cultivation of barley, wheat, peas, mustard, and potatoes. They also graze sheep, goats, yaks, horses and donkeys in the area. Fuel wood, and fodder for stall-feeding, is collected from the Park before winter. Two potential conservation threats to ibex were identified. Firstly, migratory livestock from the neighbouring areas use the area between June and August every year. ' There is no control on the numbers of animals entering the area, and the effects of grazing and trampling need to be quantified.
