Abstract: Consequences of predation may be particularly
heavy on small populations of herbivores, especially if they
are threatened with extinction. Over the 2006–2010 period, we
documented the effects of the spontaneous return of the endangered
snow leopard on the population of the vulnerable
Himalayan tahr. The study area was an area of central
Himalaya where this cat disappeared c. 40 years before, because
of persecution by man. Snow leopards occurred mainly
in areas close to the core area of tahr distribution. Tahr was the
staple (56.3 %) of snow leopards. After the arrival of this cat,
tahr decreased by more than 2/3 from 2003 to 2010 (mainly
through predation on kids). Subsequently, the density of snow
leopards decreased by 60%from2007 to 2010. The main prey
of snow leopards in Asia (bharal, marmots) were absent in our
study area, forcing snow leopards to specialize on tahr. The
restoration of a complete prey spectrum should be favoured
through reintroductions, to conserve large carnivores and to
reduce exploitation of small populations of herbivores, especially
if threatened.

Ferretti, F., Lovari, S. (2016). Predation may counteract climatic change as a driving force for movements of mountain ungulates.
Abstract: Temperature variations are expected to influence altitudinal movements of mountain herbivores and, in
turn, those of their predators, but relevant information is scarce. We evaluated monthly relationships
between temperature and altitude used by a large mountain-dwelling herbivore, the Himalayan tahr
Hemitragus jemlahicus, and its main predator, the snow leopard Panthera uncia, in an area of central
Himalaya for five consecutive years (2006–2010). In contrast to expectations, there was no significant
direct relationship between altitude of tahr sightings and temperature. The mean altitude of tahr sightings
decreased by c. 200 m throughout our study. As expected, snow leopard movements tracked those of tahr,
although the core area of the snow leopard did not move downwards. Tahr remained the staple of the
snow leopard diet: we suggest that the former did not move upwards in reaction to higher temperature
to avoid encounters with the latter. Avoidance of competition with the larger common leopard Panthera
pardus at lower altitudes could explain why snow leopards did not shift their core area downwards.
Apparently, interspecific interactions (predation; competition) influenced movements of Himalayan tahr
and snow leopards more than climatic variations.

Conservation and climate change: Assessing the vulnerability of snow leopard habitat to treeline shift in the Himalaya. Biological Conservation, 150, 129–135.
Abstract: Climate change is likely to affect the persistence of large, space-requiring species through habitat shifts,
loss, and fragmentation. Anthropogenic land and resource use changes related to climate change can also
impact the survival of wildlife. Thus, climate change has to be integrated into biodiversity conservation
plans. We developed a hybrid approach to climate-adaptive conservation landscape planning for snow
leopards in the Himalayan Mountains. We first mapped current snow leopard habitat using a mechanistic
approach that incorporated field-based data, and then combined it with a climate impact model using a
correlative approach. For the latter, we used statistical methods to test hypotheses about climatic drivers
of treeline in the Himalaya and its potential response to climate change under three IPCC greenhouse gas
emissions scenarios. We then assessed how change in treeline might affect the distribution of snow leopard
habitat. Results indicate that about 30% of snow leopard habitat in the Himalaya may be lost due to a
shifting treeline and consequent shrinking of the alpine zone, mostly along the southern edge of the range
and in river valleys. But, a considerable amount of snow leopard habitat and linkages are likely to remain
resilient to climate change, and these should be secured. This is because, as the area of snow leopard habitat
fragments and shrinks, threats such as livestock grazing, retaliatory killing, and medicinal plant collection
can intensify. We propose this approach for landscape conservation planning for other species
with extensive spatial requirements that can also be umbrella species for overall biodiversity.
