Abstract |
In the 1960s, the endangered snow leopard was locally extirpated from the Sagarmatha (Mt. Everest) region of Nepal. In this Sherpa-inhabited high Himalaya, the flourishing tourism since the ascent of Mt Everest in 1953, has caused both prosperity and adverse impacts, the concern that catalyzed the establishment of Mt. Everest National Park in the region in 1976. In the late 1980s, there were reports that some transient snow leopards may have visited the area from adjoining Tibet, but no biological surveys exist to confirm the status of the cats and their prey. Have snow leopards finally returned to the top of the world? Exploring this question was the main purpose of this research project. We systematically walked altogether 24 sign transects covering over 13 km in length in three valleys, i.e. Namche, Phortse and Gokyo, of the park, and counted several snow leopard signs. The results indicated that snow leopards have made a comeback in the park in response to decades of protective measures, the virtual cessation of hunting and the recovery of the Himalayan tahr which is snow leopard's prey. The average sign density (4.2 signs/km and 2.5 sign sites/km) was comparable to that reported from other parts of the cats' range in the Himalaya. On this basis, we estimated the cat density in the Everest region between 1 to 3 cats per 100 sq km, a figure that was supported by different sets of pugmarks and actual sightings of snow leopards in the 60 km2 sample survey area. In the study area, tahr population had a low reproductive rate (e.g. kids-to-females ratio, 0.1, in Namche). Since predators can influence the size and the structure of prey species populations through mortality and through non-lethal effects or predation risk, snow leopards could have been the cause of the population dynamics of tahr in Sagarmtha, but this study could not confirm this speculation for which further probing may be required. |

Abstract |
During November 1985 through July1996, a survey of snow leopard presence and ecology was conducted in selected areas of the states of Jammu and Kashmir, Himachal Pradesh, and Uttar Pradesh in north-western India. The study was carried out under the auspices of the Wildlife Institute of India in cooperation with the U.S. Fish and Wildlife Service and the International Snow Leopard Trust. The objectives of the survey were essentially determine the relative presence of the snow leopard and its associated prey species,investigate human interaction with the snow leopard and select an appropriate site for more intensive studies of the snow leopard and its ecosystem. |

Abstract |
The habitat of the snow leopard Uncia uncia across South and Central Asia is subject to extensive pastoral use. Levels of livestock depredation by the snow leopard and other carnivores in the region are high, and often provokes retaliatory killing by the herders. This direct threat to large carnivores is further aggravated by a depletion of wild prey due to poaching and out-competition by livestock. In this paper, we describe a pilot project in the Indian Trans-Himalaya, which uses an incentive scheme to create areas free from livestock grazing on community-owned land, thereby fostering conservation commitment among local
pastoralists, as well as contributing directly to an enhancement of wild prey density. |

Abstract |
The Trans-Himalaya is a vast biogeographic region in the cold and arid rain-shadow of
the Greater Himalaya and is spread over three Indian states. From the conservation
standpoint this region has several unique characteristics. Unlike most other
biogeographic regions of the country, it has wildlife, including large mammals, spread
over the entire region. Another feature is that the harsh climate and topography
provides limited agricultural land and pastures, all of which are currently utilized by
people. The harsh environment has given rise to a specialized assemblage of flora and fauna in
the region that include the endangered snow leopard, a variety of wild sheep and goat,
Tibetan antelope, Tibetan gazelle, kiang and wild yak. The snow leopard is one of the
most charismatic species of the Trans-Himalaya. This apex predator, with a wide
distribution, has ecological importance and international appeal, and is eminently
suitable to be used as both a 'flagship' and an 'umbrella species' to anchor and guide
conservation efforts in the Trans-Himalayan region. Among the 10 Biogeographic Zones in the country, the Trans-Himalaya has a
comparatively large Protected Area (PA) coverage, with over 15,000 km2 (8.2 %) of
the geographical area under the network. In spite of this, the bulk of the large mammal
populations still exist outside the PAs, which include highly endangered species such
as snow leopard, chiru, wild yak, Ladakh urial, kiang and brown bear. Given the sparse resource availability in the Trans-Himalaya and the existing human
use patterns, there are few alternatives that can be provided to resource dependent
human communities in and around PAs. The existing PAs themselves pose formidable
conservation challenges and a further increase in their extent is impractical. The
problem is further compounded by the fact that some of the large PAs have unclear
boundaries and include vast stretches that do not have any direct wildlife values. These
issues call for an alternative strategy for conservation of the Trans-Himalayan tracts
based on a regional perspective, which includes reconciling conservation with
development. In this paper we stress that conservation issues of this region, such as competition for
forage between wild and domestic herbivores and human-wildlife conflicts need to be
addressed in a participatory manner. We suggest an alternative scheme to look at the
zonation of existing PAs and also the Trans-Himalayan region as a whole, to facilitate
better conservation in the region. Also, we emphasize that there is a vital need for
additional resources and a formal setup for regional planning and management under a
centrally sponsored scheme such as the 'Project Snow Leopard'. |

Abstract |
Rare, elusive predators offer few sightings, hindering research with small sample sizes and lack of experimentation. While predators may be elusive, their prey are more readily observed. Prey respond to the presence of a predator, and these fear responses may have population- and community-level consequences. Anti-predator behaviors, such as vigilance, allow us to sidestep the difficulty of direct field studies of large predators by studying them indirectly. Here we used a behavioral indicator, the vigilance behavior of the Himalayan tahr, the snow leopard’s main local prey, to reveal the distribution and habitat use of snow leopards in the Mt. Everest region of Nepal. We combined techniques of conventional field biology with concepts of foraging theory to study prey behavior in order to obtain insights into the predator’s ecology. The Himalayan tahr’s vigilance behavior correlates with the distribution of snow leopard signs. Tahr actually led us to six sightings of snow leopards. We conclude that behavioral indicators provided by prey offer a valuable tool for studying and monitoring stealthy and rare carnivores. |
