Abstract |
Consequences of predation may be particularly
heavy on small populations of herbivores, especially if they
are threatened with extinction. Over the 2006–2010 period, we
documented the effects of the spontaneous return of the endangered
snow leopard on the population of the vulnerable
Himalayan tahr. The study area was an area of central
Himalaya where this cat disappeared c. 40 years before, because
of persecution by man. Snow leopards occurred mainly
in areas close to the core area of tahr distribution. Tahr was the
staple (56.3 %) of snow leopards. After the arrival of this cat,
tahr decreased by more than 2/3 from 2003 to 2010 (mainly
through predation on kids). Subsequently, the density of snow
leopards decreased by 60%from2007 to 2010. The main prey
of snow leopards in Asia (bharal, marmots) were absent in our
study area, forcing snow leopards to specialize on tahr. The
restoration of a complete prey spectrum should be favoured
through reintroductions, to conserve large carnivores and to
reduce exploitation of small populations of herbivores, especially
if threatened. |

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 |
Managing wildlife-caused damage to human interests has become an important aspect of contemporary conservation management. Conflicts between pastoralism and carnivore conservation over livestock depredation pose a serious challenge to endangered carnivores worldwide, and have become an important livelihood concern locally. Here, we first review the primary causes of these conflicts, their socio-ecological correlates, and commonly employed mitigation measures. We then describe a community-based program to manage conflicts over livestock depredation by snow leopards Panthera uncia and wolves Canis lupus. A threats-based conceptual model of conflict management is presented. Conflicts over livestock depredation are characterized by complex, multi-scale interactions between carnivore and livestock behavioral ecology, animal husbandry, human psyche, culture, world-views, and socio-economic and education levels of affected peoples. A diversity of commonly employed conflict-mitigation measures is available. They aim at (i) reducing livestock depredation through better livestock herding, use of physical, chemical or psychological barriers, removal of carnivores, and use of livestock guard animals, (ii) offsetting economic losses through damage compensation and insurance programmes, and (iii) increasing peoples’ tolerance of carnivores through indirect approaches such as conservation education and economic incentives. For effective management, conflicts need to be understood along two important dimensions, viz., the reality of damage caused to humans, and the psyche and perceptions of humans who suffer wildlife caused damage. The efficacy of commonly used mitigation measures is variable. A combination of measures that reduce the level of livestock depredation, share or offset economic losses, and improve the social carrying capacity for carnivores will be more effective in managing conflicts than standalone measures |

Abstract |
Large carnivores commonly prey on livestock when their ranges overlap. Pastoralism is the dominant land use type across the distributional range of the endangered snow leopard Panthera uncia. Snow leop- ards are often killed in retaliation against livestock depredation. Whether livestock, by forming an alter- native prey, could potentially benefit snow leopards, or, whether livestock use of an area is detrimental to snow leopards is poorly understood. We examined snow leopard habitat use in a multiple use landscape that was comprised of sites varying in livestock abundance, wild prey abundance and human population size. We photographically sampled ten sites (average size 70 sq. km) using ten camera traps in each site, deployed for a period of 60 days. Snow leopard habitat use was computed as a Relative Use Index based on the total independent photographic captures and the number of snow leopard individuals captured at each site. We quantified livestock abundance, wild prey abundance, human population size and terrain ruggedness in each of the sites. Key variables influencing snow leopard habitat use were identified using Information Theory based model selection approach. Snow leopard habitat use was best explained by wild prey density, and showed a positive linear relationship with the abundance of wild ungulates. We found a hump-shaped relationship between snow leopard habitat use and livestock stocking density, with an initial increase in habitat use followed by a decline beyond a threshold of livestock density. Our results suggest that in the absence of direct persecution of snow leopards, livestock grazing and snow leopard habitat use are potentially compatible up to a certain threshold of livestock density, beyond which habitat use declines, presumably due to depressed wild ungulate abundance and associated anthropogenic disturbance. |

Abstract |
Wildlife tourism is increasingly important for the conservation of
threatened species such as snow leopards. However, what tourists
know or value about snow leopards, and to what extent they support
the conservation of this species, has received limited empirical attention.
This paper investigates tourist knowledge about snow leopards,
beliefs and values toward the species, and support for its conservation
in the Annapurna Conservation Area of Nepal. Survey data were
collected from 406 foreign tourists between March and May 2014.
Although knowledge about snow leopards varied among respondents,
there was widespread support for their conservation.
Knowledge about snow leopards was best explained by education
level and environmental organization membership. Improved knowledge
about the species, and a variety of intrinsic conservation values,
were found to increase tourist support for snow leopard conservation.
These results provide important insights to help tailor tourism
initiatives to support the conservation of snow leopards. |

Abstract |
Accurate assessments of the status of threatened species and their conservation
planning require reliable estimation of their global populations and robust monitoring
of local population trends. We assessed the adequacy and suitability of studies
in reliably estimating the global snow leopard (Panthera uncia) population. We
compiled a dataset of all the peer-reviewed published literature on snow leopard
population estimation. Metadata analysis showed estimates of snow leopard density
to be a negative exponential function of area, suggesting that study areas have generally
been too small for accurate density estimation, and sampling has often been
biased towards the best habitats. Published studies are restricted to six of the
12 range countries, covering only 0.3�0.9% of the presumed global range of the
species. Re-sampling of camera trap data from a relatively large study site
(c.1684 km2) showed that small-sized study areas together with a bias towards
good quality habitats in existing studies may have overestimated densities by up to
five times. We conclude that current information is biased and inadequate for generating
a reliable global population estimate of snow leopards. To develop a rigorous
and useful baseline and to avoid pitfalls, there is an urgent need for
(a) refinement of sampling and analytical protocols for population estimation of
snow leopards (b) agreement and coordinated use of standardized sampling protocols
amongst researchers and governments across the range, and (c) sampling
larger and under-represented areas of the snow leopard's global range. |

Large carnivores Livestock depredation Participatory approach Snow leopard Kargil Himalaya |
|
|
Abstract |
Livestock is one of the major sources of livelihood for the
agro-pastoral communities in central and south Asia. Livestock
depredation by large carnivores is a wide-ranging issue that leads to
economic losses and a deviance from co-existence. We investigated the
grass root factors causing livestock depredation in Kargil, Ladakh and
tested the findings of diet analysis in validating reported livestock
depredation. Globally vulnerable snow leopard (Panthera uncia) and more
common wolf (Canis lupus) were the two main wild predators. A total of
1113 heads of livestock were reportedly killed by wolf (43.6%) followed
by unknown predators (31.4%) and snow leopard (21.5%) in the study site
from 2009 to 2012, which comes to 2.8% annual livestock losses. Scat
analysis also revealed a significant amount of livestock in the diet of
snow leopard (47%) and wolf (51%). Poor livestock husbandry practices
and traditional livestock corrals were found to be the major drivers
contributing in the livestock depredation. Based on the research
findings, we worked with the local communities to sensitize them about
wildlife conservation and extended limited support for predator proof
livestock corrals at a small scale. Eventually it helped in reducing
conflict level and conserving the globally threatened carnivores. We
conclude that a participatory approach has been successful to generate
an example in reducing large carnivore-human conflict in the west
Himalaya. |

Abstract |
Research on human–wildlife interactions has largely focused on the magnitude of wildlife‐caused damage, and the patterns and correlates of human attitudes and behaviors. We assessed the role of five pathways through which various correlates potentially influence human responses toward wild animals, namely, value orientation, social interactions (i.e. social cohesion and support), dependence on resources such as agriculture and livestock, risk perception and nature of interaction with the wild animal. We specifically evaluated their influence on people's responses toward two large carnivores, the snow leopard Panthera uncia and the wolf Canis lupus in an agropastoral landscape in the Indian Trans‐Himalaya. We found that the nature of the interaction (location, impact and length of time since an encounter or depredation event), and risk perception (cognitive and affective evaluation of the threat posed by the animal) had a significant influence on attitudes and behaviors toward the snow leopard. For wolves, risk perception and social interactions (the relationship of people with local institutions and inter‐community dynamics) were significant. Our findings underscore the importance of interventions that reduce people's threat perceptions from carnivores, improve their connection with nature and strengthen the conservation capacity of local institutions especially in the context of wolves. |

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. |

Abstract |
The snow leopard population in Union Territory of Ladakh (UTL), India is at the centre of five out of eight mountain ranges within the species' habitat in the high-mountain Asia. Its strategic location is of immense conservation significance to maintain genetic connectivity and metapopulation dynamics of snow leopards (Panthera uncia). Therefore, we provide the first estimates of the snow leopard's individual-based spatial genetic characteristics from UTL. Multi-locus genotyping (n = 14 loci) of individuals (n = 19) revealed moderate genetic diversity in the population (mean number of alleles = 5.86 ± 0.55, observed heterozygosity = 0.48 ± 0.05, expected heterozygosity = 0.65 ± 0.03, allelic richness = 2.65 ± 0.15). We did not observe any evidence of population structuring (using STRUCTURE and Factorial Correspondence Analysis) or isolation by distance. However, the clustering approach based on genetic distance (Nei's standard distance and Cavalli-Sforza and Edwards distance) and subsequent discriminant analysis of principal components (DAPC) revealed three sub-clusters of related individuals within the study population without any spatial correlates. We observed 1.2% first-order relatives, suggesting sufficient dispersal and panmixia in the UTL population. We observed high fixation index (FIS = 0.26 ± 0.05; 0.17 ± 0.03 upon removing loci with null alleles) and presence of individuals from genetically divergent populations in UTL. Hence, the high positive FIS value could be attributed to both Wahlund effect and inbreeding. Prioritization and effective conservation planning of the UTL population as a source would benefit the global snow leopard population by (i) maintaining connectivity between the Himalayas and the central Asian mountain ranges, and (ii) providing refuge during future climate change-related range contraction. |
