Lovari, S., Boesi, R., Minder, I., Mucci, N., Randi, E., Dematteis, A., and Ale, S. B. (2009). Restoring a keystone predator may endanger a prey species in a human-altered ecosystem: the return of the snow leopard to Sagarmatha National Park. Animal Conservation, 12, 559–570.
Abstract: Twenty-five years ago, the snow leopard Uncia uncia, an endangered large cat, was eliminated from what is now Sagarmatha National Park (SNP). Heavy hunting pressure depleted that area of most medium-large mammals, before it became a park. After three decades of protection, the cessation of hunting and the recovery of wild ungulate populations, snow leopards have recently returned (four individuals). We have documented the effects of the return of the snow leopard on the population of its main wild prey, the Himalayan tahr Hemitragus jemlahicus, a 'near-threatened' caprin. Signs of snow leopard presence were recorded and scats were collected along a fixed trail (130 km) to assess the presence and food habits of the snow leopard in the Park, from 2004 to 2006. Himalayan tahr, the staple of the diet, had a relative occurrence of 48% in summer and 37% in autumn, compared with the next most frequent prey, musk deer Moschus chrysogaster (summer: 20%; autumn: 15%) and cattle (summer: 15%; autumn: 27%). In early summer, the birth rate of tahr (young-to-female ratio: 0.8-0.9) was high. The decrease of this ratio to 0.1-0.2 in autumn implied that summer predation concentrated on young tahr, eventually altering the population by removing the kid cohort. Small populations of wild Caprinae, for example the Himalayan tahr population in SNP, are sensitive to stochastic predation events and may be led to almost local extinction. If predation on livestock keeps growing, together with the decrease of Himalayan tahr, retaliatory killing of snow leopards by local people may be expected, and the snow leopard could again be at risk of local extinction. Restoration of biodiversity through the return of a large predator has to be monitored carefully, especially in areas affected by humans, where the lack of important environmental components, for example key prey species, may make the return of a predator a challenging event.

Abstract: Background: The order Carnivora is well represented in India, with 58 of the 250 species found globally, occurring here. However, small carnivores figure very poorly in research and conservation policies in India. This is mainly due to
the dearth of tested and standardized techniques that are both cost effective and conducive to small carnivore studies in the field. In this paper we present a non-invasive genetic technique standardized for the study of Indian felids and canids with the use of PCR amplification and restriction enzyme digestion of scat collected in the field.
Findings: Using existing sequences of felids and canids from GenBank, we designed primers from the 16S rRNA region of the mitochondrial genome and tested these on ten species of felids and five canids. We selected restriction enzymes that would cut the selected region differentially for various species within each family. We produced a restriction digestion profile for the potential differentiation of species based on fragment patterns. To test our technique, we used felid PCR primers on scats collected from various habitats in India, representing varied environmental conditions. Amplification success with field collected scats was 52%, while 86% of the products used for restriction digestion could be accurately assigned to species. We verified this through sequencing. A comparison of costs across the various techniques currently used for scat assignment showed that this technique was the most practical and cost effective.
Conclusions: The species-specific key developed in this paper provides a means for detailed investigations in the future that focus on elusive carnivores in India and this approach provides a model for other studies in areas of Asia
where many small carnivores co-occur.

Abstract: We had a good sighting of two adult and one sub adult lynx together, near Ganda-la
base which is at an elevation of 4900 meter, in Hemis National Park, Ladakh, during our fieldwork on Snow leopards in February 2004.The two adults lynx were moving closer and following each other, while the sub-adult lynx was a little far from the adults.

The snow leopard in Himalaya: A step towards their conservation by studying their distribution, marking habitat selection, coexistence with other predators, and wild prey-livestock-predator interaction. Conservation Biology in Asia, , 184–196.
Abstract: Snow leopard (Uncia uncial) is a flagship species of the Himalaya. Very few studies have been done on the ecology of this species in the Himalaya. This paper presents an overview of four studies conducted on snow leopards in Nepal and India, dealing with various aspects of snow leopard ecology including their status assessment, making behaviour, habitat selection, food habits, and impact on livestock. The information generated by these studies is useful in planning effective conservation and management strategies for this endangered top predator of high mountains.

Abstract: La panthère des neiges (Uncia uncia) est un grand félin des régions montagneuses d’Asie Centrale. Elle est menacée par le braconnage et la fragmentation de son habitat. L’impact de la prédation des panthères des neiges sur le bétail a été
étudié en Mongolie. Les recherches ont porté sur la dynamique des troupeaux domestiques, l’importance numérique et financière des pertes ainsi que la perception des panthères par les éleveurs. Les panthères s’attaquent le plus souvent à des animaux de grande taille mais les éleveurs restent en majorité favorables à leur protection. Pour concilier conservation de ce prédateur et attente des communautés pastorales, un projet dénommé IRBIS ENTERPRISES a été créé. Un mécanisme assure des revenus supplémentaires aux éleveurs par la vente de produits issus du bétail en échange d’une protection total des panthères et
de leurs proies.

Abstract: Article covers the human-brown bear conflict problem, which closely parallels that of snow leopard conflict in the TAR, the peer reviewed version of: Tsering, Dawa, John D. Farrington, and Kelsang Norbu. Competition and Coexistence: Human-Wildlife Conflict in the Chang Tang Region of Tibet. Lhasa, Tibet Autonomous Region, China: Tibet People’s Publishing House, 2007.
In order to evaluate the impact of recently introduced wildlife conservation policies, a human-wildlife conflict survey of three-hundred herding households was conducted in the south-central Byang thang (Qiangtang) area of the Tibet Autonomous Region (bod rang skyongs ljongs, Xizang Zizhi Qu). Results showed that Tibetan brown bears were the largest source of human-wildlife conflict in the survey area, affecting 49 percent of surveyed households between 1990 and 2006, with a 4.5-fold increase in conflict with bears occurring since implementation of various wildlife protection policies beginning in 1993. Types of bear conflict included livestock kills, raiding of human food supplies, damage to dwellings and furnishings, and direct attacks on herders. Brown bears have caused devastating
economic losses to herders and anecdotal evidence indicates that retaliatory killing of bears by herders now poses the greatest threat to the Tibetan brown bear. Immediate measures must be taken to resolve this conflict if humans and brown
bears are to coexist in the Byang thang region.
