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. |

Abstract |
An increasing proportion of the world�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�the preferred
prey�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. |

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. |

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. |
