Abstract: The snow leopard Panthera uncia is an elusive and globally-threatened apex predator occurring in the mountain ranges of central Asia. As with other large carnivores, gaps in data on its distribution and abundance still persist. Moreover, available density estimates are often based on inadequate sampling designs or analytical approaches. Here, we used camera trapping across a vast mountainous area (area of the sampling frame 850 km2; analysed habitat extent 2600 km2) and spatially-explicit capture-recapture (SECR) models to provide, to our knowledge, the first robust snow leopard population density estimate for the Altai Mountains. This region is considered one of the most important conservation areas for snow leopards, representing a vast portion of suitable habitat and a key ecological corridor. We also provide estimates of the scale parameter (σ) that reflects ranging behaviour (activity range) and baseline encounter probability, and investigated potential drivers of density and related parameters by assessing their associations with anthropogenic and environmental factors. Sampling yielded 9729 images of snow leopards corresponding to 224 independent detections that belonged to a minimum of 23 identified adult individuals. SECR analysis resulted in an overall density of 1.31 individuals/100 km2 (1.15%–1.50 95% CI), which was positively correlated with terrain slope. This estimate falls within the mid-values of the range of density estimates for the species globally. We estimated significantly different activity range size for females and males (79 and 329 km2, respectively). Base- line encounter probability was negatively associated with anthropogenic activity. Our study contributes to on-going efforts to produce robust global estimates of population abundance for this top carnivore.

Abstract: Large carnivores can cause considerable economic damage,
mainly due to livestock depredation. These conficts instigate negative
attitude towards their conservation, which could in the extreme case
lead to retaliatory killing. Here we focus on the snow leopard (Panthera
uncia), a species of conservation concern with particularly large
spatial requirements. We conducted the study in the Bayan Olgii
province, one of the poorest provinces of Mongolia, where the majority
of the human population are traditional herders. We conducted a survey
among herders (N 261) through a semi-structured questionnaire with the
aim to assess: the current and future herding practices and prevention
measures, herders’ perceptions and knowledge of the environmental
protection and hunting laws; the perceived livestock losses to snow
leopard, wolf (Canis lupus), and wolverine (Gulo gulo), as well as to
non-predatory factors; the key factors affecting livestock losses to
these three large carnivores; and, finally, the attitudes towards these
three large carnivores. Non-predatory causes of mortality were slightly
higher than depredation cases, representing 4.5% and 4.3% of livestock
holdings respectively. While no depredation of livestock was reported
from wolverines, snow leopard and wolf depredation made up 0.2% and 4.1%
of total livestock holdings, respectively. Herders’ attitudes towards
the three large carnivores were negatively affected by the magnitude of
the damages since they had a positive overall attitude towards both snow
leopard and wolverine, whereas the attitude towards wolf was negative.
We discuss conservation and management options to mitigate herder-snow
leopard impacts. To palliate the negative consequences of the increasing
trend in livestock numbers, herd size reduction should be encouraged by
adding economic value to the individual livestock and/or by promoting
alternative income and/or ecotourism. Furthermore, co-management between
government and stakeholders would help tackle this complex problem, with
herders playing a major role in the development of livestock management
strategies. Traditional practices, such as regularly shifting campsites
and using dogs and corrals at night, could reduce livestock losses
caused by snow leopards.

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: As drivers of terrestrial ecosystems, humans have replaced large carnivores in most areas, and
human influence not only exerts striking ecological pressures on biodiversity at local scales but also has
indirect effects in distant corners of the world. We suggest that the multibillion dollar cashmere industry
creates economic motivations that link western fashion preferences for cashmere to land use in Central
Asia. This penchant for stylish clothing, in turn, encourages herders to increase livestock production which
affects persistence of over 6 endangered large mammals in these remote, arid ecosystems. We hypothesized
that global trade in cashmere has strong negative effects on native large mammals of deserts and grassland
where cashmere-producing goats are raised. We used time series data, ecological snapshots of the biomass
of native and domestic ungulates, and ecologically and behaviorally based fieldwork to test our hypothesis.
In Mongolia increases in domestic goat production were associated with a 3-fold increase in local profits for
herders coexisting with endangered saiga (Saiga tatarica). That increasing domestic grazing pressure carries
fitness consequences was inferred on the basis of an approximately 4-fold difference in juvenile recruitment among blue sheep (Pseudois nayaur) in trans-Himalayan India. Across 7 study areas in Mongolia, India, and China’s Tibetan Plateau, native ungulate biomass is now <5% that of domestic species. Such trends suggest ecosystem degradation and decreased capacity for the persistence of native species, including at least 8 Asian endemic species: saiga, chiru (Pantholops hodgsoni), Bactrian camel (Camelus bactrianus), snow leopard (Panthera uncia), khulan (Equus hemionus), kiang (E. kiang), takhi (E. przewalski), and wild yak (Bos mutus). Our results suggest striking yet indirect and unintended actions that link trophic-level effects to markets induced by the trade for cashmere.
