  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
  Year 2020 Publication bioRxiv Abbreviated Journal  
  Volume Issue Pages  
  Keywords Co-existence; land sharing; population-density; spatial capture recapture; Pseudois nayaur Capra sibirica; ungulates; livestock.  
  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 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 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.

  Title Ecosystem service dependence in livestock and crop-based Type Journal Article
  Year 2020 Publication Journal of Arid Environments Abbreviated Journal  
  Volume 180 Issue Pages 1-10  
  Keywords Provisioning services Arid ecosystems Local communities Land-use  
  Abstract Globally, in semi-arid and arid landscapes, there is an

ongoing transition from livestock-production systems to crop-production

systems, and in many parts of Asia's arid mountains, mining for minerals

is also increasing. These changes are accompanied by a change in the

generation and quality of ecosystem services (ES), which can impact

human well-being. In this study, to better understand the impacts of

such transitions, we quantified ES in two crop-based and three

livestock-based production systems in the arid and semi-arid landscapes

of the High Himalaya and Central Asia, specifically in the Indian

Himalaya, Kyrgyz Tien Shan, and Mongolian Altai. Our results showed 1)

high economic dependence (3.6–38 times the respective annual household

income) of local farmers on provisioning ES, with the economic value of

ES being greater in livestock-production systems (7.4–38 times the

annual household income) compared to crop-production systems (3.6–3.7

times the annual household income); 2) ES input into cashmere

production, the main commodity from the livestock-production systems,

was 13–18 times greater than the price of cashmere received by the

farmer; and 3) in the livestock production systems affected by mining,

impacts on ES and quality of life were reported to be negative by

majority of the respondents. We conclude that livestock-based systems

may be relatively more vulnerable to degrading impacts of mining and

other ongoing developments due to their dependence on larger ES resource

catchments that tend to have weaker land tenure and are prone to

fragmentation. In contrast to the general assumption of low value of ES

in arid and semi-arid landscapes due to relatively low primary

productivity, our study underscores the remarkably high importance of ES

in supporting local livelihoods.

  Title Relocation from wildlife reserves in the Greater and Trans-Himalayas: Is it necessary? Type Miscellaneous
  Year 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 Carnivore-Caused Livestock Mortality in Trans-Himalaya Type Miscellaneous
  Year 2007 Publication Environmental Management Abbreviated Journal  
  Volume 39 Issue Pages 490-496  
  Keywords Gya-Miru; livestock depredation; Lynx; snow leopard; trans-himalaya; wolf  
  Abstract The loss of livestock to wild predators is an important livelihood concern among Trans-Himalayan pastoralists. Because of the remoteness and inaccessibility of the region, few studies have been carried out to quantify livestock depredation by wild predators. In the present study, we assessed the intensity of livestock depredation by snow leopard Uncia uncia, Tibetan wolf Canis lupus chanku, and Eurasian lynx Lynx l. isabellina in three villages, namely Gya, Rumtse, and Sasoma, within the proposed Gya-Miru Wildlife Sanctuary in Ladakh, India. The three villages reported losses of 295 animals to these carnivores during a period of 2.5 years ending in early 2003, which represents an annual loss rate of 2.9% of their livestock holdings. The Tibetan wolf was the most important predator, accounting for 60% of the total livestock loss because of predation, followed by snow leopard (38%) and lynx (2%). Domestic goat was the major victim (32%), followed by sheep (30%), yak (15%), and horse (13%). Wolves killed horses significantly more and goats less than would be expected from their relative abundance. Snow leopards also killed horses significantly more than expected, whereas they killed other livestock types in proportion to their abundance. The three villages combined incurred an estimated annual monetary loss of approximately $USD 12,120 amounting to approximately $USD 190/household/y. This relatively high total annual loss occurred primarily because of depredation of the most valuable livestock types such as yak and horse. Conservation actions should initially attempt to target decrease of predation on these large and valuable livestock species.

  Title Habitat shift and time budget of the Tibetan argali: the influence of livestock grazing Type Miscellaneous
  Year 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 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 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 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 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 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.
