Abstract |
Understanding the impact of livestock on native
wildlife is of increasing conservation relevance. For the
Vulnerable snow leopard Panthera uncia, wild prey reduction,
intensifying human�wildlife conflicts and retaliatory
killings are severe threats potentially exacerbated by the
presence of livestock. Elucidating patterns of co-occurrence
of snow leopards, wild ungulate prey, and livestock, can be
used to assess the compatibility of pastoralism with conservation.
We used camera trapping to study the interactions of
livestock, Siberian ibex Capra sibirica and snow leopards in
a national park in the Altai mountains, Mongolia. We obtained
 detections of wild mammals and  of domestic
ungulates, dogs and humans. Snow leopards and Siberian
ibex were recorded  and  times, respectively. Co-occurrence
modelling showed that livestock had a higher estimated
occupancy (.) than ibex, whose occupancy was
lower in the presence of livestock (.) than in its absence
(.�. depending on scenarios modelled). Snow leopard
occupancy did not appear to be affected by the presence of
livestock or ibex but the robustness of such inference was
limited by uncertainty around the estimates. Although our
sampling at presumed snow leopard passing sites may have
led to fewer ibex detections, results indicate that livestock
may displace wild ungulates, but may not directly affect
the occurrence of snow leopards. Snow leopards could still
be threatened by livestock, as overstocking can trigger
human�carnivore conflicts and hamper the conservation
of large carnivores. Further research is needed to assess
the generality and strength of our results. |

Abstract |
Visual attractiveness and rarity often results in large carnivores being adopted as flagship
species for stimulating conservation awareness. Their hunting behaviour and prey selection
can affect the population dynamics of their prey, which in turn affects the population dynamics
of these large carnivores. Therefore, our understanding of their trophic ecology and foraging
strategies is important for predicting their population dynamics and consequently for
developing effective conservation programs. Here we concentrate on an endangered species
of carnivores, the snow leopard, in the Himalayas. Most previous studies on snow leopard
diet lack information on prey availability and/or did not genetically check, whether the
identification of snow leopard scats is correct, as their scats are similar to those of other
carnivores. We studied the prey of snow leopard in three Himalayan regions in Nepal
(Sagarmatha National Park (SNP), Lower Mustang (LM) and Upper Manang (UM) in the
Annapurna Conservation Area, during winter and summer in 2014�2016. We collected 268
scats along 139.3 km linear transects, of which 122 were genetically confirmed to belong to
snow leopard. Their diet was identified by comparing hairs in scats with our reference collection
of the hairs of potential prey. We determined prey availability using 32�48 camera-traps
and 4,567 trap nights. In the SNP, the most frequent prey in snow leopard faeces was the
Himalayan tahr in both winter and summer. In LM and UM, its main prey was blue sheep in
winter, but yak and goat in summer. In terms of relative biomass consumed, yak was the
main prey everywhere in both seasons. Snow leopard preferred large prey and avoided
small prey in summer but not in winter, with regional differences. It preferred domestic to
wild prey only in winter, and in SNP. Unlike most other studies carried out in the same area,
our study uses genetic methods for identifying the source of the scat. Studies solely based
on visual identification of samples may be strongly biased. Diet studies based on frequency
of occurrence of prey tend to overestimate the importance of small prey, which may be consumed
more often, but contribute less energy than large prey. However, even assessments
based on prey biomass are unlikely to be accurate as we do not know whether the actual
size of the prey consumed corresponds to the average size used to calculate the biomass
eaten. For example, large adults may be too difficult to catch and therefore mostly young animals are consumed, whose weight is much lower. We show that snow leopard consumes
a diverse range of prey, which varies both regionally and seasonally. We conclude that in
order to conserve snow leopards it is also necessary to conserve its main wild species of
prey, which will reduce the incidence of losses of livestock. |

Abstract |
Illegal trade in snow leopards (Panthera uncia) has been identified as one of the major
threats to long-term survival of the species in the wild. To quantify severity of the threats
to dwindling snow leopard population, we examined market and questionnaire surveys,
and information from the published and unpublished literature on illegal trade and
poaching of snow leopards.We collected information from 11 of the 12 snow leopard range
counties in central and southern Asia, barring Kazakhstan, and reported 439 snow leopards
(88 records) in illegal trade during 2003e2014, which represents a loss of approximately
8.4%e10.9% snow leopard population (assuming mid-point population of 5240 to
minimum population of 4000 individuals) in a period of 12 years. Our data suggested a 61%
decadal increase in snow leopard trade during 2003e2012 compared with 1993e2002,
while taking the note of significant strengthening of wildlife enforcement and crime
control network in the decades of 2000s and 2010s. We found 50% prosecution rate of
snow leopard crimes resulting in only 20% conviction rate globally. Many limitations e.g.,
secretive nature of illegal trade, ill developed enforcement mechanism, poor and passive
documentation of snow leopards' seizures, restricted us to reflect actual trend of snow
leopards' illegal trade. Even on a conservative scale the present situation is alarming and
may detrimental to snow leopard conservation. We propose an effective networking of
enforcement efforts and coordination among the law enforcement agencies, efficient
collection of data and data management, and sharing of intelligence in snow leopard range
countries, could be useful in curbing illegal trade in snow leopards in central and southern
Asia. |
