When leopards are found in human-dominated landscapes, conflicts may arise due to attacks on people or livestock loss or when people retaliate following real and perceived threats. In the plantation landscape of the Valparai plateau, we studied incidents of injury and loss of life of people and livestock over time (15 – 25 y) and carried out questionnaire surveys in 29 plantation colonies and eight tribal villages to study correlates of livestock depredation, people's perception of leopards, and preferred management options for human – leopard interactions. Leopards were implicated in an average of 1.3 (± 0.4 SE) incidents/year (1990 – 2014) involving humans and 3.6 (± 0.8 SE) incidents/year (1999 – 2014) involving livestock, with no statistically significant increasing trend over time. Most incidents of injury or loss of life involved young children or unattended livestock, and occurred between afternoon and night. At the colony level, livestock depredation was positively related to the number of livestock, but decreased with the distance from protected area and number of residents. Half the respondents reported seeing a leopard in a neutral situation, under conditions that resulted in no harm. All tribal and 52% of estate respondents had neutral perceptions of leopards and most (81.9%, n = 161 respondents) indicated changing their own behaviour as a preferred option to manage negative interactions with leopards, rather than capture or removal of leopards. Perception was unrelated to livestock depredation, but tended to be more negative when human attacks had occurred in a colony. A combination of measures including safety precautions for adults and children at night, better livestock herding and cattle-sheds, and building on people's neutral perception and tolerance can mitigate negative interactions and support continued human – leopard coexistence.

- Journal Article2016Field to a forest: Patterns of forest recovery following shifting cultivation in the Eastern HimalayaForest Ecology & Management http://dx.doi.org/10.1016/j.foreco.2016.01.006
The patterns of vegetation recovery in shifting cultivation landscapes that undergo a cycle of clearing, cultivation and forest regeneration are not well understood in Asian tropical forests. We determined for- est recovery patterns by comparing species composition, richness and forest structure in early and late fallows formed following shifting cultivation and in an uncut forest site in a mid-elevation subtropical forest in the Indian Eastern Himalaya. We also examined changes in functional traits of tree species to understand recovery processes with succession. Tree species richness in the 12, 25 and 50-year old sites was 37%, 54% and 82% the value of the richness in uncut forest, respectively, while basal area was 33%, 25% and 41% of the value in uncut forest, respectively. Species composition recovery, however, was low; with even the oldest fallow (50-year fallow) being less than 50% similar to uncut forest in terms of composition. Successional sites that recover over long periods may differ compositionally from uncut forest within a shifting cultivation landscape as these forests are often prone to other anthropogenic dis- turbances. Functional trait analysis revealed that early fallows were colonized by tree species that are animal-dispersed, insect-pollinated with small fruits and seeds, whereas uncut forest and late succes- sional forests were dominated by species that were tall, self-dispersed, wind-pollinated and of high wood density that are dominant mature forest species in the Himalaya. These results are in contrast with the patterns in functional traits of tree species in successional sites from the Neotropics. This points to the importance of site-specificity in succession following shifting cultivation.
- Journal Article2016Shifting to settled cultivation: Changing practices among the Adis in Central Arunachal Pradesh, north-east IndiaAmbio doi 10.1007/s13280-016-0765-x
In the hilly tropics, although shifting cultivation is a widespread practice, government policies have attempted to replace it with other land-uses. However, several factors determine whether farming communities can make the shift. We tried understanding the factors that facilitate or impede the shift to settled cultivation through interviews with the Adi tribe in north-east India. Although settled cultivation was initiated in the sixties, about 90 % of the families practice shifting cultivation, observing 13 festivals associated with the annual agricultural calendar. Our results indicate that the economic status of a household affected the ability to undertake settled cultivation, while labour availability is important for shifting cultivation. Often, these nuances are ignored in government policies. We conclude that future policies should be mindful of cultural and socio-economic factors that affect the community and of the social-ecological resilience of the landscapes and not use a one-size-fits-all strategy.

Habitat modification through rural and urban expansions negatively impacts most wildlife species. However, anthropogenic food sources in habitations can benefit certain species. The red fox Vulpes vulpes can exploit anthropogenic food, but human subsidies sometimes also sustain populations of its potential competitor, the free-ranging dog Canis familiaris. As human habitations expand, populations of free-ranging dog are increasing in many areas, with unknown effects on wild commensal species such as the red fox. We examined occurrence and diet of red fox along a gradient of village size in a rural mountainous landscape of the Indian Trans-Himalaya. Diet analyses suggest substantial use of anthropogenic food (livestock and garbage) by red fox. Contribution of livestock and garbage to diet of red fox declined and increased, respectively, with increasing village size. Red fox occurrence did not show a clear relationship with village size. Red fox occurrence showed weak positive relationships with density of free-ranging dog and garbage availability, respectively, while density of free-ranging dog showed strong positive relationships with village size and garbage availability, respectively. We highlight the potential conservation concern arising from the strong positive association between density of free-ranging dog and village size.

- Journal Article2016Providing more protected space for tigers Panthera tigris: a landscape conservation approach in the Western Ghats, southern IndiaOryx 50(2): 336–343Download

Conservation of large carnivores is challenging as they face various threats, including habitat loss and fragmentation. One of the current challenges to tiger Panthera tigris conservation in India is the conversion of habitat to uses that are incompatible with conservation of the species. Bringing more tiger habitat within a protected area system and in the process creating a network of connected protected areas will deliver dual benefits of wildlife conservation and protection of watersheds. Focusing on the southern Indian state of Karnataka, which holds one of the largest contiguous tiger populations, we attempted to address this challenge using a conservation planning technique that considers ecological, social and political factors. This approach yielded several conservation successes, including an expansion of the protected area network by 2,385 sq km, connection of 23 protected areas, and the creation of three complexes of protected areas, increasing the protected area network in Karnataka from 3.8 to 5.2% of the state’s land area. This represents the largest expansion of protected areas in India since the1970s. Such productive partnerships between government officials and conservationists highlight the importance of complementary roles in conservation planning and implementation.

Species diversity across several taxa ranging from plants to vertebrates is reported to decrease with altitude, or to show a mid-elevation peak in mountain systems. Plant biomass availability for herbivores is similarly expected to decline with altitude as temperature becomes limiting. However, the relationship between herbivore species richness and altitude has not been examined in detail. We show that while the overall regional pattern (gamma-richness) for 25 large-herbivore species (56 % grazers, 44 % browsers/mixed feeders) in the Western Himalayas shows a mid-elevation peak, the species richness of grazers increases nearly monotonically with altitude peaking at 4000–5000 m. Median body mass of herbivores decreased with altitude, suggesting greater suitability of higher elevations for smaller bodied herbivores. We propose that seasonal altitudinal migration patterns, biogeographic influences, increases in the abundance of graminoids, and an increase in plant nutrients with altitude might explain the unusual high grazer species richness at higher altitudes in the Himalayan Mountains.
