Wegge, P., Shrestha, R., Flagstad, O. (2012). Snow leopard Panthera uncia predation on livestock and wild prey in a mountain valley in northern Nepal: implications for conservation management. Wildlife Biology, 18(10.2981/11-049), 131–141.
Abstract: The globally endangered snow leopard Panthera uncia is sparsely distributed throughout the rugged mountains in Asia.
Its habit of preying on livestock poses a main challenge to management. In the remote Phu valley in northern Nepal, we
obtained reliable information on livestock losses and estimated predator abundance and diet composition from DNA
analysis and prey remains in scats. The annual diet consisted of 42%livestock. Among the wild prey, bharal (blue sheep/
naur) Pseudois nayaur was by far the most common species (92%). Two independent abundance estimates suggested that
there were six snow leopards in the valley during the course of our study. On average, each snow leopard killed about one
livestock individual and two bharal permonth. Predation loss of livestock estimated fromprey remains in scats was 3.9%,
which was in concordance with village records (4.0%). From a total count of bharal, the only large natural prey in the area
and occurring at a density of 8.4 animals/km2 or about half the density of livestock, snow leopards were estimated to
harvest 15.1% of the population annually. This predation rate approaches the natural, inherent recruitment rate of this
species; in Phu the proportion of kids was estimated at 18.4%. High livestock losses have created a hostile attitude against
the snow leopard and mitigation measures are needed. Among innovative management schemes now being implemented
throughout the species’ range, compensation and insurance programmes coupled with other incentive measures are
encouraged, rather than measures to reduce the snow leopard’s access to livestock. In areas like the Phu valley, where the
natural prey base consists mainly of one ungulate species that is already heavily preyed upon, the latter approach, if
implemented, will lead to increased predation on this prey, which over time may suppress numbers of both prey and
predator.

Khatiwada, J. R. & C., M.K. (2006). Status of snow leopard and conflict perception in Kangchenjunga Conservation Area, Eastern Nepal. Nepalese Journal of Zoology, 1(1), 1–8.
Abstract: Kangchenjunga Conservation Area (KCA) is situated in the Taplejung district at the north-eastern region of Nepal. Livestock keeping is the main activity of people for making a living amidst a conflict with snow leopard (Uncia uncia). Each year snow leopard kills a number of livestock resulting significant economic losses for the poor people living in this remote area. Unless the people – snow leopard conflicts is well understood and appropriate conflict management activities are implemented, the long run co-existence between people and snow leopard –especially the existence of snow leopard in this part of the world–will be in question. This has now become an utmost important as the aspiration of the people for economic development has risen significantly and the area has been open to tourism. Study was done by counting snow leopard signs walking systematically in total 18 snow leopard sign transects covering 18.01 km in length in three sites, i.e. Lonak, Khambachen and Dudhpokhari of the Conservation Area. The average sign density was 12.63/km. The livestock depredation by snow leopard for one year (2005-06) was studied by interviewing the herders to understand the responsible and specific bio-physical and economic factors. The study revealed that sub-adult yaks were mostly hunted by snow leopard. Cattle's' winter (December-April) pastures are most vulnerable sites for predation. Presence of bushes, forest and boulders and rugged mountain crevices make good hides for snow leopard. The study also showed that a lax animal guarding system was significantly responsible for high livestock depredation by snow leopard. Blue sheep was observed by walking in selected trails and from vantage points. A total of 354 individual sheep of different age and sex of 14 different herds were recorded during the study period. The study showed that improvement in livestock guarding system should be adopted as the most important activity. However despite the importance of livestock in the KCA it is still not well understood why the herders neglect for proper livestock guarding. Proper guarding system required in winter pastures to reduce the depredation pressure.

Abstract: Lean season foraging strategies are critical for the survival of species inhabiting highly seasonal environments
such as alpine regions. However, inferring foraging strategies is often difficult because of
challenges associated with empirically estimating energetic costs and gains of foraging in the field. We
generated qualitative predictions for the relationship between daily winter foraging time, body size and
forage availability for three contrasting foraging strategies including time minimization, energy intake
maximization and net energy maximization. Our model predicts that for animals employing a time
minimization strategy, daily winter foraging time should not change with body size and should increase
with a reduction in forage availability. For energy intake maximization, foraging time should not vary
with either body size or forage availability. In contrast, for a net energy maximization strategy, foraging
time should decrease with increase in body size and with a reduction in forage availability. We contrasted
proportion of daily time spent foraging by bharal, Pseudois nayaur, a dimorphic grazer, across
different body size classes in two high-altitude sites differing in forage availability. Our results indicate
that bharal behave as net energy maximizers during winter. As predicted by the net energy maximization
strategy, daily winter foraging time of bharal declined with increasing body size, and was lower in the
site with low forage availability. Furthermore, as predicted by our model, foraging time declined as the
winter season progressed. We did not find support for the time minimizing or energy intake maximizing
strategies. Our qualitative model uses relative rather than absolute costs and gains of foraging which are
often difficult to estimate in the field. It thus offers a simple way to make informed inferences regarding
animal foraging strategies by contrasting estimates of daily foraging time across gradients of body size
and forage availability.

Chundawat, R. S., & Rawat G.S. (1990). Food Habits of Snow Leopard in Ladakh, India.
Abstract: The snow leopard has remained little studied in the past, and most of the information available is either in the form of natural history or anecdotal notes. The inaccessibility of the terrain and its secretive habits make this one of the more difficult animals to study in the wild. In the past decade, several ecological surveys were conducted in India, Nepal, China and Mongolia, which gave us information on the status and distribution of snow leopard (Jackson, Mallon, Fox, Schaller, Chundawat) A detailed study in Nepal through light on its secretive habits ( Jackson and Ahlborn, 1989). Even then little is known about its feeding habits. The present paper discusses this aspect from a study which was part of a detailed study conducted on the ecology of snow leopard in India from October 1987 to Feburary 1990.

Abstract: Evidence of snow leopard presence was most abundant in C Ladakh, decreased southward toward the crest of the Himalaya, and was least on the S side of the main Himalaya. Prey populations, primarily blue sheep Pseudois nayaur and Asiatic ibex Capra ibex, were also more plentiful in the areas surveyed to the N of the main Himalaya. Perhaps 400 snow leopard occur throughout NW India. The stronghold of this species in India is apparently the trans- Himalayan ranges in Ladakh where new parks and reserves are being established, some in association with a snow leopard recovery programme of the state of Jammu and Kashmir and a 'Project Snow Leopard' of the central Indian government. Because of the generally low density of snow leopard, conservation measures must also be considered within the large areas of its range lying outside parks and reserves. -from Authors
