Programme Manager, High Altitudes
I work with local communities and government agencies to plan and implement conservation action in the high altitudes. I also support research activities in these landscapes.
I was an engineer in my past life.

Small carnivores are expected to optimize their activity to maximize prey capture and minimize their encounter with predators. We assessed the activity pattern of the stone marten
Martes foinain relation to its potential prey, the Himalayan woolly hare Lepus oiostolus and the Royle’s pika Ochotona roylei, and its predators, the red fox Vulpes vulpesand the free-ranging dog Canis familiaris. Using three years of camera trapping data from the Indian Trans-Himalaya, we estimated individual and pair-wise spatio-temporal niche width and overlap, respectively, using Levins’ asymmetric index. Stone martens showed limited space use (spatial niche width 0.16) and nocturnal activity (temporal niche width 0.35). They had high temporal (0.75) and low spatial overlap (0.05) with hares; while they had relatively low temporal (0.33) but higher spatial overlap (0.29) with pikas. Red foxes showed relatively high temporal (1.21) and spatial (0.75) overlap with martens, while free-ranging dogs showed low temporal (0.23) and spatial (0.03) overlap with martens. Although restricted space and time use by pikas might help martens track pikas even with relatively low spatio-temporal overlap, martens may be benefiting from higher temporal overlap with hares. While martens seem to be co-existing with foxes, their nocturnal activity might be driven by a trade-off between consuming prey and avoidance of diurnal predators like dogs.

India has a rich natural history record from the Himalaya spanning over a century. In this paper we provide an overview of existing knowledge on snow leopard, especially from the more recent studies. A knowledge gap analysis revealed barely 3% of its range is relatively well studied, although snow leopards occur pervasively across ca. 100,000 km2 in the Indian Himalaya. Only 37% of its range appears to be ‘good’ habitat. Based on recent density estimates and their extrapolation over the range, India is likely to support about 500 snow leopards. Threats vary regionally, but livestock grazing by migratory herders and recent developmental pressures appear to be the most serious conservation issues threatening snow leopard and other wildlife in the snow leopard range. Given the pervasive snow leopard occurrence and human pressures, the general consensus and national strategy is to formulate and implement knowledge based, participatory programmes over large landscapes.
