  Title Wild sheep and livestock in Nepal Trans-Himalaya: coexistence or competition? Type Journal Article
  Year 2008 Publication (up) Environmental Conservation Abbreviated Journal  
  Volume 32 Issue 2 Pages 125-136  
  Keywords bharal; blue sheep; diet; food habits; mountain ungulates; Nepal; pastoralism; pseudois nayaur; rangeland management; resource partitioning  
  Abstract Excessive grazing by livestock is claimed to displace wild ungulates in the Trans-Himalaya. This study compares the seasonal diets and habitat use of sympatric wild naur Pseudois nayaur and domestic goat Capra hircus, sheep Ovis aries and free-ranging yak Bos grunniens in north Nepal and analyses their overlap both within and across seasons. Alpinemeadow and the legumes Oxytropis and Chesneya were critical resources for all animal groups. High overlap occurred cross-seasonally when smallstock (sheep and goats) in summer used the spring and autumn ranges of naur. Relatively high total ungulate biomass (3028 kg km-2) and low recruitment of naur (56 young per 100 adult females in autumn) suggested interspecific competition. The spatio-temporal heterogeneity in composition and phenology of food plants across the steep gradient of altitude, together with rotational grazing, appears to indirectly facilitate coexistence of naur and smallstock. However, owing to high crossseasonal (inter-seasonal) overlaps, competition is likely to occur between these two groups at high stocking densities. Within seasons, naur overlapped more with free-ranging yak than with smallstock. As their habitat use and diets were most similar in winter, when both fed extensively on the same species of shrubs, naur was most likely to compete with yak during that season.

  Title Local attitudes to the proposed translocation of blue sheep Pseudois nayaur to Sagarmatha National Park, Nepal Type Journal Article
  Year 2018 Publication (up) Fauna & Flora International Abbreviated Journal  
  Volume Issue Pages 1-7  
  Keywords Attitudes, blue sheep, human&wildlife conflict, Panthera uncia, Pseudois nayaur, Sagarmatha National Park, snow leopard, translocation  
  Abstract Translocations are an important tool for the conservation

of biodiversity, but although ecological feasibility

studies are frequently conducted prior to implementation,

social feasibility studies that consider how local communities

perceive such projects are less common. The translocation

of blue sheep Pseudois nayaur to Sagarmatha National

Park, Nepal, has been proposed, to reduce livestock depredation

by snow leopards Panthera uncia by providing an alternative

prey base in addition to the small population of

Himalayan thar Hemitragus jemlahicus. This study used

systematic sampling, a quantitative questionnaire and qualitative

interviews within the Park to provide data on the social

viability of the proposed translocation. Quantitative

analysis revealed moderate levels of support but qualitative

analysis suggested that there are significant concerns about

the proposal. In addition,multiple regression analysis found

that women and livestock owners were significantly less

supportive, although the model had low explanatory

power. Potential crop damage and competition for forage

were frequently cited as concerns, especially amongst

those with a high level of dependence on natural resources.

Given the mixed response to the proposed translocation of

blue sheep to the Everest region, alleviating the reservations

of local residents is likely to be key to any further consultation,

planning or implementation.

  Title Status and conservation of the snow leopard Panthera uncia in Api Nampa Conservation Area, Nepal Type Journal Article
  Year 2018 Publication (up) Fauna & Flora International Abbreviated Journal  
  Volume Issue Pages 1-8  
  Keywords Api Nampa Conservation Area, bharal, Nepal, Panthera uncia, Pseudois nayaur, snow leopard  
  Abstract The snow leopard Panthera uncia is globally

threatened and reliable information on its abundance,

distribution and prey species is a prerequisite for its conservation.

In October-November 2014 we assessed the distribution

of the snow leopard in the recently established Api

Nampa Conservation Area in the Nepal Himalayas.

Within selected blocks we conducted sign surveys and

counted the number of bharal Pseudois nayaur, its principal

wild prey, along transects totalling 106 km.We recorded 203

putative snow leopard signs at an encounter rate of 1.91

signs/km. Generalized linear models of the number of

signs detected per transect showed that elevation had a positive

influence and human activities a negative influence on

sign encounter rate; prey abundance had only a weak positive

influence on sign encounter rate. Within the effectively

surveyed area of c. 2002 km2, we counted 527 bharal at an estimated

density of 2.28 animals/km2. Recruitment of bharal

was low, estimated at 48 kids/100 adult females, most likely a

result of poor or overgrazed rangeland. We estimate

the total number of bharal in this conservation area to be

.>1,000, a prey base that could sustain 6-9 snow leopards.

Based on our field observations, we identified human disturbance

and habitat degradation associated with extraction

of non-timber forest products, livestock grazing, and poaching

as the main threats to the snow leopard. Standardized

sign surveys, preferably supplemented by sampling with

remote cameras or with genetic analysis of scats would

provide robust baseline information on the abundance of

snow leopards in this conservation area.

  Title Blue sheep strongly affect snow leopard relative abundance but not livestock depredation in the Annapurna Conservation Area, Nepal Type Journal Article
  Year 2022 Publication (up) Global Ecology and Conservation Abbreviated Journal  
  Volume 37 Issue e02153 Pages 1-15  
  Keywords Co-existence, Himalayan marmot, Human-wildlife conflict, Intervention strategy, Panthera uncia, Pseudois nayaur  
  Abstract Large carnivores play key roles in their ecosystems, but their protection is a major challenge in biodiversity conservation due to conflicts with human interests. The snow leopard (Panthera uncia) is the top predator of Asian high-altitude landscapes and faces various threats including wild prey depletion and illegal killings as a consequence of livestock depredation. As the interactions between snow leopards, wild prey, and livestock are still insufficiently understood, we studied the effects of 1) wild prey (blue sheep Pseudois nayaur and Himalayan marmots Marmota himalayana) and domestic prey on snow leopard relative abundance, and of 2) these ecological parameters and intervention applications on livestock depredation by snow leopards. In the Annapurna Conservation Area, Nepal, we monitored wildlife populations and livestock along transects (490.8 km) in 82 grid cells (4 ×4 km) in 2019 and 2021 and conducted questionnaire surveys to determine livestock depredation between 2018 and 2021 (n = 479 households). We applied generalized linear models (GLMs) and sample comparison testing to examine the effects of prey densities and other environmental and anthropogenic predictors on snow leopard relative abundance and livestock depredation. Blue sheep density strongly positively affected snow leopard relative abundance, which also increased with terrain ruggedness and decreased with increasing densities of livestock and the human population. The size of livestock holdings shaped depredation events of large livestock (yak, cattle and horse), whereas depredation events of sheep and goats, which accounted for most (68.6%) depredated animals, decreased with increasing human population density and marmot presence. The strong impact of blue sheep on snow leopard relative abundance supports demands for integrating this ungulate into conservation and management plans, including wild prey recovery and translocation. The rather weak evidence for effects of blue sheep on depredation events suggests that conflicts over livestock depredation by snow leopards would neither be inflicted nor solved by increasing wild prey abundance. This demonstrates the need to improve intervention strategies in the Annapurna region, such as predator-proofing corrals and optimizing daytime herding practices. We suggest further exploring the effects of marmots and other secondary prey on livestock depredation rates, and testing the suitability of additional interventions, e.g., dogs and deterrents, as conflict mitigation tools. Our results will support wildlife managers in setting conservation priorities to promote the long-term co-existence of local people and snow leopards.

  Title People, predators and perceptions: patterns of livestock depredation by snow leopards and wolves Type Journal Article
  Year 2013 Publication (up) Journal of Applied Ecology Abbreviated Journal  
  Volume 50 Issue Pages 550-560  
  Keywords Canis lupus, Capra ibex, human–wildlife conflict, large carnivores, Panthera uncia, Pseudois nayaur, trans-Himalaya  
  Abstract 1. Livestock depredation by large carnivores is an important conservation and economic concern

and conservation management would benefit from a better understanding of spatial variation

and underlying causes of depredation events. Focusing on the endangered snow leopard

Panthera uncia and the wolf Canis lupus, we identify the ecological factors that predispose

areas within a landscape to livestock depredation. We also examine the potential mismatch

between reality and human perceptions of livestock depredation by these carnivores whose

survival is threatened due to persecution by pastoralists.

2. We assessed the distribution of the snow leopard, wolf and wild ungulate prey through field

surveys in the 4000 km2 Upper Spiti Landscape of trans-Himalayan India. We interviewed local

people in all 25 villages to assess the distribution of livestock and peoples’ perceptions of the risk

to livestock from these carnivores. We monitored village-level livestock mortality over a 2-year

period to assess the actual level of livestock depredation. We quantified several possibly influential

independent variables that together captured variation in topography, carnivore abundance

and abundance and other attributes of livestock. We identified the key variables influencing livestock

depredation using multiple logistic regressions and hierarchical partitioning.

3. Our results revealed notable differences in livestock selectivity and ecological correlates of

livestock depredation – both perceived and actual – by snow leopards and wolves. Stocking

density of large-bodied free-ranging livestock (yaks and horses) best explained people’s threat

perception of livestock depredation by snow leopards, while actual livestock depredation was

explained by the relative abundance of snow leopards and wild prey. In the case of wolves,

peoples’ perception was best explained by abundance of wolves, while actual depredation by

wolves was explained by habitat structure.

4. Synthesis and applications. Our results show that (i) human perceptions can be at odds

with actual patterns of livestock depredation, (ii) increases in wild prey populations will intensify

livestock depredation by snow leopards, and prey recovery programmes must be accompanied

by measures to protect livestock, (iii) compensation or insurance programmes should

target large-bodied livestock in snow leopard habitats and (iv) sustained awareness

programmes are much needed, especially for the wolf.

  Title Habitat relationships between wild and domestic herbivores in Nepalese trans – Himalaya Type Journal Article
  Year 2008 Publication (up) Journal of Arid Environments Abbreviated Journal  
  Volume 72 Issue Pages 914-925  
  Keywords blue sheep; Competition; domestic; habitat partitioning; naur; Nepal; pastoralism; pseudois nayaur; trans-himalaya  
  Abstract In the semi-arid ecosystems of Asia, where pastoralism is a main subsistence occupation, grazing competition from domestic stock is believed to displace the wild ungulates. We studied the habitat relationships among sympatric naur and domestic yak and smallstock in Phu valley in upper Manang district, Nepal, on the basis of their distribution on vegetation types, elevation and slope. To control for the disturbance effect by humans, we collected the data on naur from those ranges where domestic stock were not being attended by herders. We applied correspondence analysis to explore habitat associations among animal groups (n ¬ 1415) within and across-seasons. Within each association, interspecific habitat overlaps and species habitat preferences were calculated. Naur was strongly associated with free-ranging yak as they used similar altitudinal ranges in all seasons, except in spring. Their distributions on vegetation types and slopes were also quite similar, except for a stronger preference for alpine meadows by naur during summer and winter. Naur and smallstock did not form temporal associations as the latter consistently used lower elevations. In autumn and spring, however, naur spatially overlapped with the summer range of smallstock, and both preferred the alpine meadow habitat during these periods. Alpine meadow was the least abundant vegetation type but was consistently and preferentially used by all animal groups across seasons. At high stocking densities, all three animals groups are therefore likely to compete for this vegetation type. The role of spatio-temporal heterogeneity for interpreting the interspecific relationships among ungulates in the semi-arid rangelands of the trans-Himalaya is discussed.

  Title Snow leopards and blue sheep in Nepal: Densities and predator: Prey ratio Type Miscellaneous
  Year 1994 Publication (up) Journal of Mammalogy Abbreviated Journal  
  Volume 75 Issue Pages 998-1004  
  Keywords snow leopard,Panthera uncia,blue sheep,Pseudois nayaur,density,predator:prey ratio,harvest rate,livestock predation,Nepal  
  Abstract I studied snow leopards (Panthera uncia) and blue sheep (Pseudois nayaur) in Manang District, Annapurna Conservation Area, Nepal, to estimate numbers and analyze predatorprey interactions. Five to seven adult leopards used the 105-km2 study area, a density of 4.8 to 6.7 leopards/100 km2. Density of blue sheep was 6.6-10.2 sheep/km2, and biomass density was 304 kg/km2. Estimated relative biomass consumed by snow leopards suggested that blue sheep were the most important prey; marmots (Marmota himalayana) also contributed significantly to the diet of snow leopards. Snow leopards in Manang were estimated to harvest 9-20% of total biomass and 11-24% of total number of blue sheep annually. Snow leopard :blue sheep ratio was 1 :1 14-1 :159 on a weight basis, which was considered sustainable given the importance of small mammals in the leopard's diet and the absence of other competing predators.

  Title Summer diets of wild and domestic ungulates in Nepal Himalaya Type Journal Article
  Year 2005 Publication (up) Journal of Zoology Abbreviated Journal  
  Volume 266 Issue Pages 111-119  
  Keywords argali; blue sheep; Capra hircus; diet; faecal analysis; fecal analysis; mountain ungulates; Ovis ammon hodgsoni; pseudois nayaur  
  Abstract The selection of summer forage by three sympatric ungulates in the Damodar Kunda region of upper Mustang in

north Nepal was studied to assess the extent of food overlap between them. To compare their diets, a microhistological technique of faecal analysis was used, adjusted for inherent biases by comparing it with bite-count data obtained in domestic goats. Tibetan argali Ovis ammon hodgsoni, naur (blue sheep or bharal) Pseudois nayaur and domestic goat Capra hircus consumed mostly forbs, graminoids and browse, respectively. The proportions of food items in their diets were significantly different both at the plant species (P<0.02) and at the forage category level (P<0.001). Except for sharing three common plants (Agrostis sp., Stipa sp. and Potentilla fruticosa), dietary overlap at the species level was quite low. At the forage category level, naur and domestic goat overlapped more than the other ungulate pairs. Although all three species were opportunistic, mixed feeders, argali was a more selective forb specialist grazer than the other two ungulates. Owing to some spatial separation and little dietary overlap, interspecific competition for summer forage was low. If animal densities increase, however, goats are expected to compete more with naur than with argali because of their more similar diets. Owing to differences in forage selection by argali and naur throughout their large geographical ranges, reflecting adaptations to local ecological conditions, inferences regarding forage competition between domestic livestock and these two wild caprins need to be made from local, site-specific studies, rather than from general diet comparisons.

  Title Habitat segregation between sympatric Tibetan argali Ovis ammon hodgsoni and blue sheep Pseudois nayaur in the Indian Trans-Himalaya Type Journal Article
  Year 2004 Publication (up) Journal of Zoology Abbreviated Journal  
  Volume 262 Issue Pages 57-63  
  Keywords argali; Ovis ammon hodgsoni; blue sheep; pseudois nayaur; Habitat selection; resource partitioning; niche relationship; 5200  
  Abstract Tibetan argali Ovis ammon hodgsoni and blue sheep Pseudois nayaur have almost completely overlapping distributions encompassing most of the Tibetan plateau and its margins. Such a sympatric distribution of related species with similar ecological requirements implies that there is some degree of resource partitioning. This may be accomplished on the basis of habitat and/or diet separation. This study evaluated such ecological separation on the basis of physical habitat partitioning by these two sympatric ungulates in Hemis High Altitude National Park, Ladakh, India, in an area where the argali established a small new population in 1978. Such separation was tested for

on the basis of expected difference between the species in their proximity to cliffs, associated with species-specific anti-predator behaviour. Tibetan argali selected habitats away from cliffs while blue sheep selected habitats close to cliffs. Blue sheep also selected steep slopes whereas argali selected gentle slopes. The two species did not differ

in their use of habitats in terms of elevation. They did, however, differ in their use of plant communities; blue sheep selected sub-shrub and grass-dominated communities whilst argali selected forb-dominated communities. We suggest that the two species coexist in this site as a result of the differential use of habitat associated with their

species-specific anti-predator strategies.
