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.

Lovari, S., Minder, I., Ferretti, F., Mucci, N., Randi, E., Pellizzi, B. (2013). Common and snow leopards share prey, but not habitats: competition avoidance by large predators. Journal of Zoology, 291, 127–135.
Abstract: Resource exploitation and behavioural interference underlie competition among
carnivores. Competition is reduced by specializing on different prey and/or spatiotemporal
separation, usually leading to different food habits. We predicted that
two closely related species of large cats, the endangered snow leopard and the
near-threatened common leopard, living in sympatry, would coexist through
habitat separation and exploitation of different prey species. In central Himalaya,
we assessed (2006–2010) habitat and diet overlap between these carnivores. The
snow leopard used grassland and shrubland, whereas the common leopard
selected forest. Contrary to our prediction, snow leopard and common leopard
preyed upon similar wild (Himalayan tahr, musk deer) and domestic species (Bos
spp., dogs). Dietary overlap between snow leopard and common leopard was 69%
(yearly), 76% (colder months) and 60% (warmer months). Thus, habitat separation
should be the result of other factors, most likely avoidance of interspecific
aggression. Habitat separation may not always lead to the use of different prey.
Avoidance of interspecific aggression, rather than exploitation of different
resources, could allow the coexistence of potentially competing large predators.

Li, J., Yin, H., Wang, D., Jiagong, Z., Lu, Zhi. (2013). Human-snow leopard conflicts in the Sanjiangyuan Region of the Tibetan Plateau. Biological Conservs, (166), 118–123.
Abstract: Conflicts between humans and snow leopards are documented across much of their overlapping distribution
in Central Asia. These conflicts manifest themselves primarily in the form of livestock depredation
and the killing of snow leopards by local herders. This source of mortality to snow leopards is a key conservation concern. To investigate human-snow leopard conflicts in the Sanjiangyuan Region of the Tibetan Plateau, we conducted household interviews about local herders’ traditional use of snow leopard
parts, livestock depredation, and overall attitudes towards snow leopards. We found most respondents
(58%) knew that snow leopard parts had been used for traditional customs in the past, but they claimed
not in the past two or three decades. It may be partly due to the issuing of the Protection of Wildlife Law
in 1998 by the People’s Republic of China. Total livestock losses were damaging (US$ 6193 per household
in the past 1 year), however snow leopards were blamed by herders for only a small proportion of those
losses (10%), as compared to wolves (45%) and disease (42%). Correspondingly, the cultural images of
snow leopards were neutral (78%) and positive (9%) on the whole. It seems that human-snow leopard
conflict is not intense in this area. However, snow leopards could be implicated by the retaliatory killing
of wolves. We recommend a multi-pronged conservation program that includes compensation, insurance
programs, and training local veterinarians to reduce livestock losses.

Murali, R., Redpath, S., Mishra, C. (2017). The value of ecosystem services in the high altitude Spiti Valley, Indian Trans-Himalaya. Elsevier, (28), 115–123.
Abstract: The high mountain ranges of South and Central Asia are increasingly being exposed to large-scale development
projects. These areas are home to traditional pastoralist communities and internationally important
biodiversity including the endangered snow leopard Panthera uncia. Development projects rely on
economic cost-benefit analysis, but the ecosystem services in the high Himalayas are poorly understood
and are rarely accounted for. As a first step to fill this gap, we identified the main ecosystem services used
by local people in the Trans-Himalayan Spiti Valley (7591 km2), a region important for conservation of
snow leopards and high mountain biodiversity, and undertook an economic valuation. Stakeholders identified
a range of services, though these were dominated by provisioning services identified by 90% of
respondents. Only 5.4% of the respondents recognised regulatory services and 4.8% recognised cultural
services. The mean economic value of provisioning services was estimated at US$ 3622 ± 149 HH1
yr1, which was 3.8 times higher than the average annual household income. Our results underscore
the need to account for ecosystem services in the cost-benefit analyses of large-scale development projects
in addition to assessments of their environmental and social impact.

Abstract: There is a growing agreement that conservation needs to be proactive and pay increased attention to common species and to the threats they face. The blue sheep (Pseudois nayaur) plays a key ecological role in sensitive high-altitude ecosystems of Central Asia and is among the main prey species for the globally vulnerable snow leopard (Panthera uncia). As the blue sheep has been increasingly exposed to human pressures, it is vital to estimate its population dynamics, protect the key populations, identify important habitats, and secure a balance between conservation and local livelihoods. We conducted a study in Manang, Annapurna Conservation Area (Nepal), to survey blue sheep on 60 transects in spring (127.9 km) and 61 transects in autumn (134.7 km) of 2019, estimate their minimum densities from total counts, compare these densities with previous estimates, and assess blue sheep habitat selection by the application of generalized additive models (GAMs). Total counts yielded minimum density estimates of 6.0–7.7 and 6.9–7.8 individuals/km2 in spring and autumn, respectively, which are relatively high compared to other areas. Elevation and, to a lesser extent, land cover indicated by the normalized difference vegetation index (NDVI) strongly affected habitat selection by blue sheep, whereas the effects of anthropogenic variables were insignificant. Animals were found mainly in habitats associated with grasslands and shrublands at elevations between 4,200 and 4,700 m. We show that the blue sheep population size in Manang has been largely maintained over the past three decades, indicating the success of the integrated conservation and development efforts in this area. Considering a strong dependence of snow leopards on blue sheep, these findings give hope for the long-term conservation of this big cat in Manang. We suggest that long-term population monitoring and a better understanding of blue sheep–livestock interactions are crucial to maintain healthy populations of blue sheep and, as a consequence, of snow leopards.
