My broad research interests lie in distribution patterns of large mammals, ecological-social-cultural determinants of species persistence in a landscape, co-occurrence-competition dynamics, impact of socio-economic development and resource extraction/use in wildlife rich areas, interactions and impact of non-native species on native wildlife and human-wildlife interactions and/or conflict. I am particularly interested in the high altitude landscapes of the Himalaya and Trans-Himalaya, although tropical ecosystems intrigue me equally.
I am currently involved in research on high altitude mammals. For my post-doctoral research I'm loking at depredation ecology of snow leopards in relation to domestic and wild-prey. For Ph.D., I examined how snow leopard and its primary prey bharal and Asiatic ibex are distributed in the Himalaya and Trans-Himalaya ranges of Himachal Pradesh and what affects their distribution at multiple scales. I also looked at how migratory livestock grazing impacts vegetation and wild-prey of snow leopard. My previous works include surveying northern Himachal for understanding occurrences of snow leopard and its prey using secondary information. For my M.Sc. dissertation I looked at how a commensal species, red fox, responds towards village size and free-ranging dog. I have been involved in snow leopard and prey population estimation surveys, management planning and capacity building.

Snow leopard, an elusive mammal species of the cat family, is the top-predator of the Central and South Asian, highaltitude ecosystem. Snow leopards occur at low densities across the Central Asian mountains and the Indian Himalayan region. Owing to their secretive nature and inaccessible habitat, little is known about its ecology and distribution. Due to its endangered status and high aesthetic value, the snow leopard is considered as an ‘umbrella species’ for wildlife conservation in the Indian Himalayas. This article summarizes the current knowledge on snow leopard ecology and conservation issues in the Indian context.

The data set has occupancy values and local extinction probability values for 88 grids/sites of 15km X 15km each, for snow leopard, blue sheep, Asiatic ibex and wild prey (blue sheep and ibex combined), across an area of 14,616 sq.km in the Himalaya and Trans-Himalaya mountains of Himachal Pradesh, India.

Intense livestock grazing outcompetes wild-ungulates in low-productivity rangelands. This is a long-standing and highly debated conservation problem globally. We examined impacts of migratory livestock grazing on Trans-Himalayan rangeland and Asiatic ibex, a wild-ungulate and primary prey of the endangered snow leopard. Vegetation and ibex were sampled in an intensely grazed (livestock density 63 sheep-goat/km2) and ungrazed areas, during spring (before-grazing), summer (during-grazing) and autumn (after-grazing). Proportionate to vegetated area, independent randomly laid 1mX1m plots were sampled for vegetation cover and biomass estimation (Cover: NUngrazed=237; NGrazed=127; Biomass: NUngrazed=119; NGrazed=64). Ibex density and young:adult-female ratios were estimated by repeatedly sampling 17 trails using double-observer method across both treatments for the three time periods and two consecutive years. Graminoid and herb biomass were significantly higher in ungrazed than grazed area (ANOVA; Graminoid: FTreatment=16.05; P=<0.001; Herb: FTreatment=22.75; P=< 0.001). Overall vegetation composition was dissimilar across ungrazed and grazed area (Morisita Index 0.18), however, palatable species composition was similar (Morisita Index 0.70). Biomass of palatable species was 2.25 times higher in ungrazed than grazed area. Total off-take of dry forage by migratory livestock from grazed pastures (61 km2) was 10,658 kgs km-2 over two months of grazing. Ibex density was 1.80-7.0 times higher in ungrazed than grazed area in 2015, while 2.45-4.7 times higher in ungrazed than grazed area during 2016. Ibex yearling:adult-female ratio was six times higher in ungrazed than grazed area. Significant reduction in forage availability lowered ibex density and yearling:adult-female ratios in grazed area, suggesting migratory livestock outcompetes ibex through exploitative competition.

Understanding species distributions, patterns of change and threats can form the basis for assessing the conservation status of elusive species that are difficult to survey. The snow leopard Panthera uncia is the top predator of the Central and South Asian mountains. Knowledge of the distribution and status of this elusive felid and its wild prey is limited. Using recall-based key-informant interviews we estimated site use by snow leopards and their primary wild prey, blue sheep Pseudois nayaur and Asiatic ibex Capra sibirica, across two time periods (past: –; recent: –) in the state of Himachal Pradesh, India. We also conducted a threat assessment for the recent period. Probability of site use was similar across the two time periods for snow leopards, blue sheep and ibex, whereas for wild prey (blue sheep and ibex combined) overall there was an % contraction. Although our surveys were conducted in areas within the presumed distribution range of the snow leopard, we found snow leopards were using only % of the area (, km). Blue sheep and ibex had distinct distribution ranges. Snow leopards and their wild prey were not restricted to protected areas, which encompassed only % of their distribution within the study area. Migratory livestock grazing was pervasive across ibex distribution range and was the most widespread and serious conservation threat. Depredation by free-ranging dogs, and illegal hunting and wildlife trade were the other severe threats. Our results underscore the importance of community-based, landscape- scale conservation approaches and caution against reliance on geophysical and opinion-based distribution maps that have been used to estimate national and global snow leopard ranges.
