Title Spatial variation in population-density, movement and detectability of snow leopards in 2 a multiple use landscape in Spiti Valley, Trans-Himalaya Type Journal Article

Abstract The endangered snow leopard Panthera uncia occurs in human use landscapes in the mountains of South and Central Asia. Conservationists generally agree that snow leopards must be conserved through a land-sharing approach, rather than land-sparing in the form of strictly protected areas. Effective conservation through land-sharing requires a good understanding of how snow leopards respond to human use of the landscape. Snow leopard density is expected to show spatial variation within a landscape because of variation in the intensity of human use and the quality of habitat. However, snow leopards have been difficult to enumerate and monitor. Variation in the density of snow leopards remains undocumented, and the impact of human use on their populations is poorly understood. We examined spatial variation in snow leopard density in Spiti Valley, an important snow leopard landscape in India, via spatially explicit capture recapture analysis of camera trap data. We camera trapped an area encompassing a minimum convex polygon of 953 km . We estimated an overall density of 0.49 (95% CI: 0.39-0.73) adult snow leopards per 100 km . Using AIC, our best model showed the density of snow leopards to depend on wild prey density, movement about activity centres to depend on altitude, and the expected number of encounters at the activity centre to depend on topography. Models that also used livestock biomass as a density covariate ranked second, but the effect of livestock was weak. Our results highlight the importance of maintaining high density pockets of wild prey populations in multiple use landscapes to enhance snow leopard conservation.

Title A Regional Perspective for Snow Leopard Conservation In the Indian Trans-Himalaya Type Conference Article
Year 2002 Publication Abbreviated Journal
Volume Issue Pages (up)
Keywords snow; leopard; India; indian; Himalaya; Himalayan; conservation; region; regional; climate; topography; flora; fauna; Tibet; tibetan; protected; area; planning; management; manage; biogeographic; gazelle; kiang; yak; predator; 4900
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'.

Title Assessing changes in distribution of the Endangered snow leopard Panthera uncia and its wild prey over 2 decades in the Indian Himalaya through interviewbased occupancy surveys Type Journal Article
Year 2017 Publication Oryx Abbreviated Journal
Volume Issue Pages (up) 1-13
Keywords Asiatic ibex, blue sheep, carnivore, occupancy, snow leopard, survey, threat, ungulate
Abstract Understanding species distributions, patterns of

change and threats can form the basis for assessing the conservation

status of elusive species that are difficult to survey.

The snow leopard Panthera uncia is the top predator of the

Central and South Asian mountains. Knowledge of the distribution

and status of this elusive felid and its wild prey is

limited. Using recall-based key-informant interviews we estimated

site use by snow leopards and their primary wild

prey, blue sheep Pseudois nayaur and Asiatic ibex Capra

sibirica, across two time periods (past: &#63281;&#63289;&#63288;&#63285;&#65533;&#63281;&#63289;&#63289;&#63282;; recent:

&#63282;&#63280;&#63280;&#63288;&#65533;&#63282;&#63280;&#63281;&#63282;) in the state of Himachal Pradesh, India. We

also conducted a threat assessment for the recent period.

Probability of site use was similar across the two time periods

for snow leopards, blue sheep and ibex, whereas for wild

prey (blue sheep and ibex combined) overall there was an

&#63288;% contraction. Although our surveys were conducted in

areas within the presumed distribution range of the snow

leopard, we found snow leopards were using only &#63287;&#63285;% of

the area (&#63281;&#63284;,&#63286;&#63281;&#63286; km&#63282;). Blue sheep and ibex had distinct distribution

ranges. Snow leopards and their wild prey were not

restricted to protected areas, which encompassed only &#63281;&#63287;%

of their distribution within the study area. Migratory livestock

grazing was pervasive across ibex distribution range

and was the most widespread and serious conservation

threat. Depredation by free-ranging dogs, and illegal hunting

and wildlife trade were the other severe threats. Our

results underscore the importance of community-based, landscape-

scale conservation approaches and caution against reliance

on geophysical and opinion-based distribution maps that have been used to estimate national and global snow leopard ranges.

Title VALUATION OF ECOSYSTEM SERVICES IN SNOW LEOPARD LANDSCAPES OF ASIA Type Report
Year 2017 Publication Abbreviated Journal
Volume Issue Pages (up) 1-46
Keywords
Abstract Snow leopards occur in Asia&#65533;s high mountain ranges of the Himalayas, Hindu Kush, Karakoram, Pamir, Tien Shan, Kunlun, Altai and Sayan. In all the 12 countries where they occur, snow leopards face intensifying threats to their survival, including habitat fragmentation and degradation due to increasing human populations, mining and developmental projects, poaching and illegal wildlife trade, weak law enforcement, inadequate involvement of local people in conservation efforts, and depletion of natural prey populations due to hunting by people and overgrazing by livestock.

To address the urgent needs of conservation of the snow leopard and the sustainable development of mountain peoples, the Governments of snow leopard range countries came together and agreed to invest efforts to conserve snow leopards in 23 large landscapes across its range under the Global Snow Leopard Ecosystem Protection Program (GSLEP).

These landscapes where the snow leopards occur are inhabited by agro-pastoral and pastoral peoples who depend on well functioning ecosystems for ecosystem services, i.e., the benefits that humans derive from nature. Many threats that impact snow leopards also impact the well-being of people living in these landscapes. However, till date, there have been no studies that have attempted to quantify peoples&#65533; dependence on ecosystem services in snow leopard landscapes, or understand the impacts that alternate land-use decisions such as mining or infrastructure can have on the ecosystem services and on the local people who are dependent on them.

In this report, we provide the first assessment of the economic value of provisioning ecosystem services &#65533; the material goods from ecosystems &#65533; used by local people in five study sites from four GSLEP landscapes: Spiti Valley and Changtang region of Ladakh in India&#65533;s Hemis-Spiti Landscape, Gurez Valley in the Himalayan Landscape of Pakistan, Tost Nature Reserve in the South Gobi Landscape of Mongolia, and the Sarychat region in the Central Tien Shan Landscape of Kyrgyzstan. In study sites that had both pastoral and agro-pastoral communities, we estimated ecosystem services separately for the two production systems.The average value (± SE) of ecosystem services per household amongst the agro-pastoral

communities of Gurez Valley (4125 ± 190 USD/HH/yr) was 2.5 times the average local household income. In the agro-pastoral communities of Spiti Valley (3964 ± 334.8 USD/HH/yr) it was 3.6 times the average local household income, while it was 3.7 times amongst the agro-pastoral communities of Changtang (15083 ± 1656 USD/HH/yr). Amongst the pastoral communities, the value of ecosystem services used by households was several times higher than the average household income: it was 26.1 times amongst the pastoral communities of Changtang (79303 ± 9204 USD HH/yr), 38.7 times among communities in Tost Nature Reserve (150100 ± 13290 USD/HH/yr), and 7.4 times among the pastoral communities of Sarychat (25473 ± 5236 USD/HH/yr). It was lower, although still substantial at 0.6 times, for the downstream agro-pastoral communities living outside the landscape boundary in Sarychat (2094 ± 189 USD/HH/yr).

Our work reveals substantially high levels of dependence of local communities on ecosystem services provided by snow leopard landscapes of Asia. The estimated economic value of provisioning ecosystem services used by human households in these landscapes ranged from 0.6 to up to 40 times the local annual household incomes. This economic support that nature provides people is critical for humanity but remains hidden and unaccounted for. Land use change decisions, especially those that are damaging for nature and biodiversity, must start accounting for the value of ecosystem services in their cost-benefit analyses.

Title Change in snow leopard predation on livestock after revival of wild prey in the Trans-Himalaya Type Journal Article
Year 2020 Publication Wildlife Biology Abbreviated Journal
Volume Issue Pages (up) 1-11
Keywords arid ecosystems, diet analysis, human-wildlife conflict, Panthera, predator, rangeland
Abstract Human–wildlife conflict arising from livestock-losses to large carnivores is an important challenge faced by conservation. Theory of prey–predator interactions suggests that revival of wild prey populations can reduce predator’s dependence on livestock in multiple-use landscapes. We explore whether 10-years of conservation efforts to revive wild prey could reduce snow leopard’s Panthera uncia consumption of livestock in the coupled human-and-natural Trans-Himalayan ecosystem of northern India. Starting in 2001, concerted conservation efforts at one site (intervention) attempted recovery of wild- prey populations by creating livestock-free reserves, accompanied with other incentives (e.g. insurance, vigilant herding). Another site, 50km away, was monitored as status quo without any interventions. Prey remains in snow leopard scats were examined periodically at five-year intervals between 2002 and 2012 to determine any temporal shift in diet at both sites to evaluate the effectiveness of conservation interventions. Consumption of livestock increased at the status quo site, while it decreased at the intervention-site. At the intervention-site, livestock-consumption reduced during 2002–2007 (by 17%, p = 0.06); this effect was sustained during the next five-year interval, and it was accompanied by a persistent increase in wild prey populations. Here we also noted increased predator populations, likely due to immigration into the study area. Despite the increase in the predator population, there was no increase in livestock-consumption. In contrast, under status quo, dependence on livestock increased during both five-year intervals (by 7%, p=0.08, and by 16%, p=0.01, respectively). These contrasts between the trajectories of the two sites suggest that livestock-loss can potentially be reduced through the revival of wild prey. Further, accommodating counter-factual scenarios may be an important step to infer whether conservation efforts achieve their targets, or not.

Abstract The Ladakh urial (Ovis vignei vignei) is a highly endangered animal (IUCN Red List 2000) listed in the Appendix 1 of CITES and Schedule 1 of the Indian Wildlife Protection Act 1972. Its numbers had been reduced to a few hundred individuals in the 1960s and 70s through hunting for trophies and meat (Fox et al. 1991, Mallon 1983, Chundawat and Qureshi 1999, IUCN Red List 2000). However, with the protection bestowed by the IWPA 1972, and resultant decrease in hunting, the population seems to have shown a marginal increase to about 1000-1500 individuals in its range in Ladakh (Chundawat and Qureshi 1999, IUCN Red List 2000). Although the species had in the past, been able to coexist with the predominantly Buddhist society of Ladakh, the recent increase in the population of both humans and their livestock has placed immense pressures on its habitat (Shackleton 1997, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). This is especially important considering that the Ladakh urial habitat coincides with the areas of maximum human activity in terms of settlements, agriculture, pastoralism and development, in Ladakh (Fox et al. 1991, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). Increased developmental activities such as construction of roads, dams, and military bases in these areas have also increased the access to their habitat. This has consequently made the species more vulnerable to the threats of poaching and habitat destruction (Fox et al. 1991, Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2002). Pressure from increased livestock grazing is one of the major threats faced by the species today (Shackleton 1997, Fox et al. 1991, Mallon 1983, IUCN Red List 2000 Chundawat and Qureshi 1999, Raghavan and Bhatnagar 2003). In the impoverished habitat provided by the Trans-Himalayas, there is great competition for the scarce resources between various animal species surviving here (Fox 1996, Mishra 2001). The presence of livestock intensifies this competition and can either force the species out of its niche (competitive exclusion) by displacing it from that area or resource, or lead to partitioning of resources between the species, spatially or temporally, for coexistence (Begon et al. 1986, Gause 1934).

Title Why should a grazer browse? Livestock impact on winter resource use by bharal Pseudois nayaur Type Journal Article

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.

Title Impact of wild prey availability on livestock predation by snow leopards Type Journal Article
Year 2017 Publication Royal Society Open Science Abbreviated Journal
Volume Issue Pages (up) 1-11
Keywords apparent competition, apparent facilitation, conservation conflicts, indirect interactions, predator&#65533; prey interactions, snow leopard
Abstract An increasing proportion of the world&#65533;s poor is rearing

livestock today, and the global livestock population is growing.

Livestock predation by large carnivores and their retaliatory

killing is becoming an economic and conservation concern.

A common recommendation for carnivore conservation and

for reducing predation on livestock is to increase wild prey

populations based on the assumption that the carnivores

will consume this alternative food. Livestock predation,

however, could either reduce or intensify with increases

in wild prey depending on prey choice and trends in

carnivore abundance. We show that the extent of livestock

predation by the endangered snow leopard Panthera uncia

intensifies with increases in the density of wild ungulate

prey, and subsequently stabilizes. We found that snow leopard

density, estimated at seven sites, was a positive linear

function of the density of wild ungulates&#65533;the preferred

prey&#65533;and showed no discernible relationship with livestock

density. We also found that modelled livestock predation

increased with livestock density. Our results suggest that

snow leopard conservation would benefit from an increase

in wild ungulates, but that would intensify the problem of

livestock predation for pastoralists. The potential benefits of

increased wild prey abundance in reducing livestock predation

can be overwhelmed by a resultant increase in snow leopard

populations. Snow leopard conservation efforts aimed at

facilitating increases in wild prey must be accompanied by greater assistance for better livestock

protection and offsetting the economic damage caused by carnivores.
