- Book2014Nature Without BordersOrient Blackswan
Nature Without Borders explores the ways in which conservation of biodiversity can coexist with human actions and interests through a series of different essays. While wildlife conservation in India has traditionally depended on fencing off fragments of areas and habitats and guarding them against human encroachment, such an approach is limited in value, given that formally designated Protected Areas occupy a very small proportion of territory and that nature and natural processes transcend human boundaries and cannot be contained within the borders of nature reserves. Effective conservation, therefore, cannot ever depend on limiting or excluding human activity when habitats and environments themselves have porous boundaries.
Recent research, moreover, shows that effective conservation efforts can occur beyond the borders of Protected Areas and within human settlements. This eclectic collection of essays explores this more inclusive form of conservation through case studies that focus on different species, different environments (whether urban or rural), and different social and political constituencies from local farming or fishing communities to the educated middle class to corporate interests and the state. The essays range from overfishing along the Indian shoreline to the fate of the Gangetic river dolphin and from Sarus Cranes in the rice fields of Uttar Pradesh to the enigmatic snow leopard in the Himalayas. They explore the pastures of the Deccan plateau and the plantations of the Western Ghats as well as the lakes of Bengaluru and urban forests in Delhi. In sum, they offer readers insight into the scope of inclusive conservation that adapts its principles and practices to human activity across a diversity of environments and contexts.
This book will be of interests to students and scholars of ecology and environmental studies, environmental history and sociology. It will also be of interest to nature and conservation specialists and activists as well as policy makers and planners.

PDF, 3.64 MB
Many bat species occur in Indian coffee plantations and despite sporadic reports of damage to commercial coffee crops, the literature shows little evidence for these claims. Measures that have been proposed to ‘control’ fruit bats are likely to be ineffective and even counter-productive. Instead, insect-eating bats should be encouraged by planters as they help control herbivorous and disease-carrying insects, while fruit bats pollinate flowers and disperse seeds of many useful plants and shade tree species. More research is needed to quantify any crop damage caused by bats and to look for sustainable solutions where necessary.

Foot-and-mouth disease (FMD) had made its way into the mountains from the plains of Pasighat in Arunachal Pradesh. The worst affected were the semi-domesticated mithun (Bos frontalis) that were dying out even as their owners watched helplessly. Each day, as one more animal was found dead in the forest or beside the road, another few were seen salivating profusely from the mouth as the infection spread rapidly.

Intra and interspecific variation in frugivore behaviour can have important consequences for seed dispersal outcomes. However, most information comes from among-species comparisons, and within-species variation is relatively poorly understood. We examined how large intraspecific differences in the behaviour of a native disperser, blackbuck antelope Antilope cervicapra, influence dispersal of a woody invasive, Prosopis juliflora, in a grassland ecosystem. Blackbuck disperse P. juliflora seeds through their dung. In lekking blackbuck populations, males defend clustered or dispersed mating territories. Territorial male movement is restricted, and within their territories males defecate on dung-piles. In contrast, mixed-sex herds range over large areas and do not create dung-piles. We expected territorial males to shape seed dispersal patterns, and seed deposition and seedling recruitment to be spatially localized. Territorial males had a disproportionately large influence on seed dispersal. Adult males removed twice as much fruit as females, and seed arrival was disproportionately high on territories. Also, because lek-territories are clustered, seed arrival was spatially highly concentrated. Seedling recruitment was also substantially higher on territories compared with random sites, indicating that the local concentration of seeds created by territorial males continued into high local recruitment of seedlings. Territorial male behaviour may, thus, result in a distinct spatial pattern of invasion of grasslands by the woody P. juliflora. An ex situ experiment showed no beneficial effect of dung and a negative effect of light on seed germination. We conclude that large intraspecific behavioural differences within frugivore populations can result in significant variation in their effectiveness as seed dispersers. Mating strategies in a disperser could shape seed dispersal, seedling recruitment and potentially plant distribution patterns. These mating strategies may aid in the spread of invasives, such as P. juliflora, which could, in turn, negatively influence the behaviour and ecology of native dispersers.
