Title Habitat shift and time budget of the Tibetan argali: the influence of livestock grazing Type Miscellaneous
Year (up) 2007 Publication Ecological Resources Abbreviated Journal
Volume 22 Issue Pages 25-31
Keywords habitat shift; livestock; Tibetan argali; Time budget; trans-himalaya
Abstract Livestock production is the primary source of livelihood and income in most of the high steppe and alpine regions of the Indian Trans-Himalaya. In some areas, especially those established or proposed for biodiversity conservation, recent increases in populations of domestic livestock, primarily sheep and goats, have raised concern about domestic animals competitively excluding wild herbivores from the rangelands. We

evaluated the influence of domestic sheep and goat grazing on the habitat use and time budget of the endangered Tibetan argali Ovis ammon hodgsoni in the proposed Gya-Miru Wildlife Sanctuary, Ladakh, India. We asked if the domestic sheep and goat grazing and collateral human activities relegate the argali to suboptimal habitats, and alter their foraging time budgets. Data were collected on habitat use and time budget of a population of c. 50 argalis before and after c. 2,000 sheep and goats moved onto their winter pasture in the Tsabra catchment of the aforementioned reserve. Following the introduction of domestic sheep and goats, argalis continued to use the same catchment but shifted to steeper habitats, closer to cliffs, with lower vegetation cover, thus abandoning previously used plant communities with denser cover. Argalis' active time spent foraging also decreased by 10% in response to the presence of livestock. These results suggest a clear disturbance effect of livestock on argalis, and indicate a potential for competition, conceivably a significant disadvantage for argalis in winter when forage availability is minimal.

Title Vigilance behaviour of the Tibetan argali Ovis ammon hodgsoni in the Indian Trans-Himalaya Type Journal Article
Year (up) 2007 Publication Acta Zoologica Sinica Abbreviated Journal
Volume 53 Issue Pages 195-200
Keywords Tibertan argali, Ovis ammon, vigilance, dilution effect, Ladakh, Trans-Himalaya
Abstract An inverse relationship between individual vigilance level and group size is widely reported in many behavioral studies on animals across several taxa. It is generally held that such a relationship is due to a reduced probability of an individual being killed in larger groups. in the present investigation, I studied the vigilance behavior of the endangered Tibetan argali Ovis ammon hodgsoni in relation to group size and escape terrain. I hypothesized that an individual argali has a higher vigilance level in smaller groups and in habitats closer to cliffs than individuals living in larger groups and open areas (escape terrain). The results show that the vigilance of argali decreased with increasing group size, but there was no effect of escape terrain on its vigilance behavior. There were significant differences between age-sex groups: male, female and yearling in their time budgets. Females, compared to males and yearlings, spent more time being vigilant. They also foraged more and moved less than males. It is suggested that vigilance is an important anti-predator behavior amongst argali sheep.

Title Relocation from wildlife reserves in the Greater and Trans-Himalayas: Is it necessary? Type Miscellaneous
Year (up) 2008 Publication Conservation and Society Abbreviated Journal
Volume 6 Issue 3 Pages 263-270
Keywords wildlife reserves,relocation,Greater Himalayas,Trans-Himalayas; wildlife; reserves; relocation; Himalayas; Himalaya; trans-himalaya; transhimalaya
Abstract The Greater and Trans-Himalayan tracts are cold deserts that have severe seasonal and resource scarce environments. Covering the bulk of Indian Himalayas, they are a rich repository of biodiversity values and ecosystem services. The region has a large protected area (PA) network which has not been completely effective in conserving these unique values. The human population densities are much lower (usually < 1 per sq km) than in most other parts of the country (over 300 to a sq km). However, even such small populations can come into conflict with strict PA laws that demand large inviolate areas, which can mainly be achieved through relocation of the scattered settlements. In this paper, I reason that in this landscape relocation is not a tenable strategy for conservation due to a variety of reasons. The primary ones are that wildlife, including highly endangered ones are pervasive in the larger landscape (unlike the habitat 'islands' of the forested ecosystems) and existing large PAs usually encompass only a small proportion of this range. Similarly, traditional use by people for marginal cultivation, biomass extraction and pastoralism is also as pervasive in this landscape. There does exist pockets of conflict and these are probably increasing owing to a variety of changes relating to modernisation. However, scarce resources, the lack of alternatives and the traditional practice of clear-cut division of all usable areas and pastures between communities make resettlement of people outside PAs extremely difficult. It is reasoned that given the widespread nature of the wildlife and pockets of relatively high density, it is important to prioritise these smaller areas for conservation in a scenario where they form a mosaic of small 'cores' that are more effectively maintained with local support and that enable wildlife to persist. These ideas have recently gained widespread acceptance in both government and conservation circles and may soon become part of national strategy for these areas.

Title Habitat relationships between wild and domestic herbivores in Nepalese trans – Himalaya Type Journal Article
Year (up) 2008 Publication 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 Why should a grazer browse? Livestock impact on winter resource use by bharal Pseudois nayaur Type Journal Article
Year (up) 2009 Publication Oecologia Abbreviated Journal
Volume Issue Pages 1-10
Keywords browse; livestock; impact; winter; resource; use; bharal; Pseudois; pseudois nayaur; Pseudois-nayaur; nayaur; diet; variation; diets; conservation; Media; study; decline; areas; area; grazing; Pressure; plants; plant; sign; feeding; location; population; structure; populations; using; young; Female; times; High; Competition; species; predators; predator; endangered; snow; snow leopard; snow-leopard; leopard; trans-himalaya; transhimalaya
Abstract Many mammalian herbivores show a temporal diet variation between graminoid-dominated and browse dominated diets. We determined the causes of such a diet shift and its implications for conservation of a medium sized ungulate-the bharal Pseudois nayaur. Past studies show that the bharal diet is dominated by graminoids (>80%) during summer, but the contribution of graminoids declines to about 50% in winter. We tested the predictions generated by two alternative hypotheses explaining the decline: low graminoid availability during winter causes bharal to include browse in their diet; bharal include browse, with relatively higher nutritional quality, in their diet to compensate for the poor quality of graminoids during winter. We measured winter graminoid availability in areas with no livestock grazing, areas with relatively moderate livestock grazing, and those with intense livestock grazing pressures. The chemical composition of plants contributing to the bharal diet was analysed. The bharal diet was quantiWed through signs of feeding on vegetation at feeding locations. Population structures of bharal populations were recorded using a total count method. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. The bharal diet was dominated by graminoids (73%) in areas with highest graminoid availability. Graminoid contribution to the bharal diet declined monotonically (50, 36%) with a decline in graminoid availability. Bharal young to female ratio was 3 times higher in areas with high graminoid availability than areas with low graminoid availability. The composition of the bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Our results suggest that bharal include more browse in their diet during winter due to competition from livestock for graminoids. Since livestock grazing reduces graminoid availability, creation of livestock-free areas is necessary for the conservation of grazing species such as the bharal and its predators including the endangered snow leopard in the Trans-Himalaya.

Abstract Decline of wild prey populations in the Himalayan region, largely due to competition with livestock, has been identified as one of the main threats to the snow leopard Uncia uncia. Studies show that bharal Pseudois nayaur diet is dominated by graminoids during summer, but the proportion of graminoids declines in winter. We explore the causes for the decline of graminoids from bharal winter diet and resulting implications for bharal conservation. We test the predictions generated by two alternative hypotheses, (H1) low graminoid availability caused by livestock grazing during winter causes bharal to include browse in their diet, and, (H2) bharal include browse, with relatively higher nutrition, to compensate for the poor quality of graminoids during winter. Graminoid availability was highest in areas without livestock grazing, followed by areas with moderate and intense livestock grazing. Graminoid quality in winter was relatively lower than that of browse, but the difference was not statistically significant. Bharal diet was dominated by graminoids in areas with highest graminoid availability. Graminoid contribution to bharal diet declined monotonically with a decline in graminoid availability. Bharal young to female ratio was three times higher in areas with high graminoid availability than areas with low graminoid availability. No starvation-related adult mortalities were observed in any of the areas. Composition of bharal winter diet was governed predominantly by the availability of graminoids in the rangelands. Since livestock grazing reduces graminoid availability, creation of livestock free areas is necessary for conservation of grazing species such as the bharal and its predators such as the endangered snow leopard in the Trans-Himalaya.

Title People, predators and perceptions: patterns of livestock depredation by snow leopards and wolves Type Journal Article
Year (up) 2013 Publication 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 A penny saved is a penny earned: lean season foraging strategy of an alpine ungulate Type Journal Article
Year (up) 2014 Publication Animal Behaviour Abbreviated Journal
Volume Issue 92 Pages 93-100
Keywords blue sheep, grazing, herbivore, mountain ungulate, optimal foraging, Pseudois nayaur, trans-Himalaya
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.

Title What Factors Predispose Households in Trans-Himalaya (Central Nepal) to Livestock Predation by Snow Leopards? Type Journal Article
Year (up) 2020 Publication Animals Abbreviated Journal
Volume 10 Issue 2187 Pages 1-14
Keywords human-snow leopard conflict; livestock predation; Narphu valley; trans-Himalaya
Abstract Livestock depredation across the trans-Himalaya causes

significant economic losses to pastoralist communities. Quantification

of livestock predation and the assessment of variables associated with

depredation are crucial for designing effective long-term mitigation

measures. We investigated the patterns and factors of livestock

depredation by snow leopards (Panthera uncia) using semi-structured

questionnaires targeting herders in the Narphu valley of the Annapurna

Conservation Area, Nepal. During the two years (2017/18 and 2018/19),

73.9% of the households interviewed (n = 65) lost livestock to snow

leopards, with an annual average loss of two livestock per household. Of

the total depredation attributed to snow leopards, 55.4% were yak

(mainly female: 79%), 31.7% goat, 6.8% sheep, 3.2% horse and 2.8%

cattle. Results from applying Generalized Linear Mixed Models (GLMMs)

revealed the total number of livestock owned and the number of larger

bodied livestock species as the main explanatory covariates explaining

livestock depredation. Forty-one (41%) of all herders considered snow

leopard’s preference for domestic livestock as the main factor in

livestock predation, whereas only 5% perceived poor herding practice as

the main reason for the loss. Our study found poor and changing herding

practices in the valley, whereby 71% herders reported careful herding as

a solution to snow leopard depredation, and 15% of herders considered

the complete extermination of snow leopards as the best solution to the

problem. Tolerance levels and awareness among herders towards snow

leopard conservation is increasing, mainly due to the Buddhist religion

and strict law enforcement within this protected area. We recommend the

effective implementation of a community-based livestock insurance scheme

to compensate the economic loss of herders due to predation and improved

herding practices as the recommended mitigation measures for ensuring

livestock security and snow leopards’ conservation in the valley.

Title Multiple factors influence local perceptions of snow leopards and Himalayan wolves in the central Himalayas, Nepal. Type Journal Article
Year (up) 2020 Publication PeerJ Abbreviated Journal
Volume Issue Pages 1-18
Keywords Panthera uncia, Canis lupus chanco, Perceptions, Large carnivores, Trans-Himalayas
Abstract An understanding of local perceptions of carnivores is

important for conservation and management planning. In the central

Himalayas, Nepal, we interviewed 428 individuals from 85 settlements

using a semi-structured questionnaire to quantitatively assess local

perceptions and tolerance of snow leopards and wolves. We used

generalized linear mixed effect models to assess influential factors,

and found that tolerance of snow leopards was much higher than of

wolves. Interestingly, having experienced livestock losses had a minor

impact on perceptions of the carnivores. Occupation of the respondents

had a strong effect on perceptions of snow leopards but not of wolves.

Literacy and age had weak impacts on snow leopard perceptions, but the

interaction among these terms showed a marked effect, that is, being

illiterate had a more marked negative impact among older respondents.

Among the various factors affecting perceptions of wolves, numbers of

livestock owned and gender were the most important predictors. People

with larger livestock herds were more negative towards wolves. In terms

of gender, males were more positive to wolves than females, but no such

pattern was observed for snow leopards. People’s negative perceptions

towards wolves were also related to the remoteness of the villages.

Factors affecting people’s perceptions could not be generalized for the

two species, and thus need to be addressed separately. We suggest future

conservation projects and programs should prioritize remote settlements.
