A global biodiversity hotspot and one of the most irreplaceable areas for conservation, this region has a staggering plant and animal diversity overlapping with a dense human population. In this region, our work focuses on human impacts on wild species and habitats, biological surveys, human-wildlife conflict research and mitigation, and ecological restoration.
Wildlife and Human Ecology
The Western Ghats forests, rivers, and grasslands contain an extraordinary diversity of species, including rare and threatened species and endemics found nowhere else in the world. These species survive in landscapes that are a mix of protected and human-use areas. Understanding plant and animal ecology, human impacts on wildlife species, and how people use and relate to natural resources is all critical for conservation and these motivate our research in the region.

Policy and Outreach
Translating scientific research results and understanding to lasting changes on the ground involves communicating to a wide variety of stakeholders. There is also a need to translate ideas for change into policy and practice, whether it is to transform land use practices or to reap the benefits of conservation. Towards these ends, we continue to engage with policy and outreach in the Western Ghats.

Loss of mature tropical forests to agricultural expansion often creates landscapes with forest fragments embedded within a matrix of human-modified habitats and land uses. Such habitat fragmentation may be detrimental to species with specialized habitat and foraging requirements and their ability to persist in such landscapes may depend on their adaptability to habitat modification. Great Hornbills Buceros bicornis, among the largest birds in Asian tropical rainforests, depend on large trees for nesting and a diverse array of patchily distributed fruiting trees. In the human-modified landscape of the Anamalai Hills, India, we compared the breeding biology and nesting behaviour of Great Hornbills in contiguous rainforest (N=3 nests) and in modified habitat consisting of coffee plantations and rainforest fragments (N=5 nests). The nesting cycle of seven of the eight nests monitored varied between 114 and 130 days. Nest provisioning behaviour was similar in contiguous forest and modified habitat in terms of visitation and food delivery rates, but visitation tended to be higher and food delivery rate lower during the nestling phase than during incubation. As expected, tree density and native food plant diversity were lower in modified habitat than in continuous forest. The diversity of food provisioned was lower in modified habitat with a 57.5% dietary overlap with contiguous forest. Hornbills in the modified habitat of coffee plantations used non-native tree species for nesting and foraging, indicating their adaptability to modified landscapes.

Developmental activities have been one of the major drivers of conversion of natural forest areas into mosaics of forest fragments, agriculture, and plantations, threatening the existence of wildlife species in such altered landscapes. Most conservation research and actions are protected area centric and seldom addresses the importance of landscape matrices around these protected areas in providing habitats to a wide range of species. In this article, we bring out the crucial role of natural and anthropogenic habitats for the existence of three charismatic species, namely, Asian elephants, leopard, and lion-tailed macaques. The larger public perception of where the animals should be and where the animals actually are is also discussed. We emphasize that, while habitat generalists often adapt behaviorally and ecologically to modified landscapes, habitat specialists, such as the lion-tailed macaques could find survival harder, with increasing anthropogenic pressures and loss of their habitats.
- Book2018Pillars of Life: Magnificent Trees of the Western GhatsNature Conservation Foundation, Mysore.
For millions of years, the forests of the Western Ghats mountains have been home to a host of extraordinary trees. These range from the peculiar conifer, Nageia, whose family origins can be traced back to the age of the dinosaurs, to the grand trees in the rudraksh family, to the jack and fig trees that occupy a familiar presence in India’s forests and countryside. This book showcases thirty remarkable tree species through beautiful illustrations and artwork. It conveys the wonder arising from the beauty, the diversity, the individuality, and magnificence of trees in the Western Ghats, and evokes a greater sensitivity to the diverse values and enrichment that trees bring to our lives.

Increasing anthropogenic pressures on forests, especially in the tropical regions of the world, have restricted several large mammalian species such as the Asian elephant to fragmented habitats within human-dominated landscapes. In this study, we assessed the effects of an anthropogenic landscape and its associated conflict with humans on the physiological stress responses displayed by Asian elephants in the Anamalai Hills of the Western Ghats mountains in south India. We have quantified faecal glucocorticoid metabolite (FGM) concentrations in focal individual elephants within and across herds, inhabiting both anthropogenic and natural habitats, and evaluated their physiological responses to different socio-ecological situations between November 2013 and April 2014. Physiological stress responses varied significantly among the tested elephant age- and sex categories but not across different types of social organisation. Adults generally showed higher FGM concentrations, even in the absence of stressors, than did any other age category. Males also appeared to have higher stress responses than did females. Although there was no significant variation in mean stress levels between elephants on the plateau in the absence of human interactions and those in adjacent, relatively undisturbed forest habitats, FGM concentrations increased significantly for adult and subadult individuals as well as for calves following drives, during which elephants were driven off aggressively by people. Our study emphasises the general importance of understanding individual variation in physiology and behaviour within a population of a seriously threatened mammalian species, the Asian elephant, and specifically highlights the need for long-term monitoring of the stress physiology and behavioural responses of individual elephants across both human-dominated and natural landscapes. Such studies would not only provide comprehensive insights into the adaptive biology of elephants in changing ecological regimes but also aid in the development of effective management and conservation strategies for endangered populations of the species.

The fragmentation of the rainforests of India’s Western Ghats mountains has left the endemic lion-tailed macaque surviving in numerous forest patches in a mosaic of commercial tea and coffee plantations. On the Valparai Plateau, Anamalai Hills, some macaque groups have evidently altered their behavior, becoming habituated to people, suffering from frequent roadkill, and facing problems related to people feeding them and their use of open waste dumps. We carried out a questionnaire survey around three rainforest fragments (Puthuthottam, Korangumudi, Old Valparai) and the town of Valparai to understand people’s perceptions towards macaques, and to identify appropriate conflict-mitigation measures. Macaques near Korangumudi and Old Valparai rarely ventured near residences, and most people were unaware of their presence. Respondents in and around Puthuthottam were aware of the macaques, and most (68%) had negative perceptions of them because the macaques often visited houses in the area. Most respondents (87%) believed that macaques visited houses in search of food and garbage, and 84% reported that macaques were doing this only over the last 10 years. Housing conditions influenced people's perceptions: people living in tiled-roof houses that were vulnerable to incursions by the macaques had higher negative perceptions (84.5%) compared to people living in asbestos-roof and concrete structures. To reduce negative interactions with people and promote harmonious human-macaque co-existence, we suggest implementing a combination of measures that would involve plantation management, conservation organizations, and the state forest and municipal authorities. The measures include cost-effective monkey-proofing of houses, regular garbage collection, preventing open waste disposal and the feeding of macaques, mitigating the effects of roads, and promoting people’s awareness, rainforest restoration, and the use of native shade trees in plantations.
