    Interaction of Kiang (Equus kiang) with Livestok in Hanley Valley of Chanthang Wildlife Sanctuary, Ladakh
    (Wildlife Institute of India, Dehradun, 2009) Hussain, Asif; Qureshi, Qamar; Rawat, G.S.
    Hanley Valley «320 41' 27" N 790 04' 3.5") in Eastern Ladakh forms the western most extension of Tibetan plateau and has been recognized as an important biogeographic province in India (Indian Trans-Himalaya). This region harbors a rich array of wild and domestic ungulates. The area is also home to nomadic Changpa and Tibetan refugee herders. The political, social and ecological transformations have altered previous, well-established links between the pastoral population and their rangeland environment. Over the years, with growing integration of the local economy of Ladakh and with better development of cash markets, the pastoral community is fast losing its tolerance towards the kiang and it is increasingly seen as a competitor to livestock. The purpose of this study was to document this intensifying conflict between pastoralism and Kiang conservation, using resource selection functions. Data on habitat variables were collected on 4 fixed trails of varying length (3- 7 km) for kiang (with and without livestock presence) and livestock for use availability analysis. For food habits, micro-histological method in case of kiang and bite count method in case of livestock was used. Data on activity pattern of kiang was collected to examine change in response to livestock presence. Density and encounter rates were estimated using vehicle transects (n=5) of varying lengths (5-56 km). Livestock were followed (focal animal sampling) from dawn to dusk to estimate amount of forage removed. Availability of different habitat variables was estimated using ArcGIS 9.2. Total of 104 kiang groups before arrival of livestock and 187 kiang groups after livestock arrival to the area were recorded. Habitat use by kiang and livestock was significantly different (8 = 0.00016, P < 0.05). Habitat use by kiang before and after livestock arrival was found to be significantly different (8 = 0.013, P <0.05). Groups of kiang were observed (n=14) for time budget evaluation, 7 prior (640 min) and 7 (820 min) after livestock had come to the area. Activity pattern of kiang before and after livestock arrival was found to be significantly different (8 = 0.04, P <0.05). Food preference for kiang before and after livestock arrival was not found to be significantly different. Food preference for kiang and livestock was significantly different (6= 0.0000007, P < 0.05). Use-availability analysis suggested differential selection for food plants. Schoener's niche overlap for food items found moderate overlap between kiang, sheep and goat «60%) and high overlap between kiang and horse (>80%). Forage removed (kg) by sheep, goat and horse were 2.33 kg, 2.25 and 8.19 kg respectively. Total density and encounter rate for Hanley valley was 0.07 kiang/km2 and 0.45 kiang per km respectively. The difference in habitat use translated into Kiang using higher elevations while livestock used middle elevations more than available. Kiang used steep slopes whereas livestock used steep as well as gentle slopes more than available. Kiang used North-West aspect more than available. Kiang used vegetation communities dominated by graminoides while sheep-goat used communities dominated by shrub and forbs. Density and encounter estimates did not show considerable increase in kiang population compared to previous studies. Hence, the perception of people of kiang overstocking in the study area appears to be misplaced. Detailed perception studies should be carried out in the whole of Changthang and herder-centered participatory programmes need to be carried out on a large scale to ensure long term conservation of kiang in eastern Ladakh.

    Interactions Between Livestock and Ladakh Urial (Ovis vignei vigei)
    (Wildlife Institute of India, Dehradun, 2003) Raghavan, Bindu; Bhatnagar, Yashveer; Qureshi, Qamar
    The Ladakh urial is a highly endangered and endemic subspecies of wild sheep. Past hunting pressures had decimated the population to extremely low levels. Recent estimates (1,000-1,500 individuals) suggest a marginal increase in numbers. The Ladakh urial occupies plateaus and gentle slopes along the lowermost elevations in the Indus and Shyok Valleys, areas that are easily accessible and heavily used by humans. This is also the most heavily populated area and due to geopolitical reasons, receives the highest developmental benefits. Due to such changes the Ladakh urial may be highly vulnerable to population decimation. Pastoralism is a way of life in bulk of the Ladakh Trans-Himalaya; a region Where wildlife including endangered species such as the urial and snow leopard are not restricted inside wildlife Protected Areas alone. Such species thus share their habitat with the over 3,00,000 livestock that occurs in the region. Recent studies from the Trans Himalaya have indicated competition with livestock as an important reason for the decimation of wild herbivore populations. This study thus aimed to investigate the interactions between the endangered Ladakh urial and livestock during the winter of 2002-03, a season of resource scarcity. We investigated the habitat selection of the Ladakh urial and its separation with livestock at the level of space, habitat variables and diet, to gather evidence for competition. Four trails were walked 10 times each to obtain information on the habitat usage by the urial and livestock. Further information on livestock use was gathered from the herders using semi-structured interviews and resource maps. Diet of both urial and livestock was investigated by examining recently foraged sites using 10, 1 mX1 m quadrats at each such site. All sightings from the trails were plotted on a 1 :50,000 501 Toposheet. A 500mX500m grid was overlaid on these locations to obtain the grids used exclusively by the urial and livestock and by both together to calculate spatial separation. Both, Ladakh urial and livestock primarily used the mid elevation zones (4,121- 4,400m) with gentle to moderate inclination (<30°). However, along the elevation gradient there was some separation in that the urial used the uppermost elevations to a substantial degree (44%) even during the cold winter season, which livestock avoided.The findings of this study thus show that the habitat and diet requirements of Ladakh urial and livestock sharing the range were similar during the winter season. The relatively high use of the sparsely vegetated uppermost elevations of the range by urial, where the cost of foraging is likely to be higher than the mid-elevations suggests that the urial were excluded from these areas by the livestock. We also reason that the relatively poor young:100 adult female ratio (31:100) may be a manifestation of the stress provided by such competition with livestock and survival in sub-optimal habitats.
