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. | ||||

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 | Snow leopard Panthera uncia predation on livestock and wild prey in a mountain valley in northern Nepal: implications for conservation management | Type | Journal Article | ||

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. |

Title | People, predators and perceptions: patterns of livestock depredation by snow leopards and wolves | Type | Journal Article | ||
Year | 2013 | Publication | Journal of Applied Ecology | Abbreviated Journal | |

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 | 2014 | Publication | Animal Behaviour | Abbreviated Journal | |

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. |

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. |
