Hunting by local communities is among the most wide- spread threats to Indian wildlife, yet, the understanding of its nature, extent, and impacts on wildlife has been poor. We surveyed 2 protected areas—Kudremukha and Na- gara-holé—in southern India to assess the impacts of local hunting on large mammals. Detailed interviews with retired and active hunters were employed to describe hunting patterns. Impacts of hunting were assessed by comparing large-mammal abundance in adjacent sites differing in their vulnerability to hunting. In Kudremukha, at least 26 species of mammals were hunted, mostly with guns, at an esti- mated intensity of 216 hunter-days per month per village. In Nagaraholé, 6 of the 9 focal species of large mammals occurred at significantly lower densities at the heavily hunted site where enforcement capabilities were poorer. Our data underscore the importance of preservationist programs in the conservation of large mammals in a context of extensive local hunting.

The subcontinent of India occupies a large area of the tropical Indian Ocean, but it has a scant growth of coral reefs along its coasts. Several factors limit reef development here, chief among them being turbid waters stirred by monsoonal systems, fresh water runoff from rivers, and a heavy human population and development pressure along the entire coastline. The island complexes around India, in contrast, show healthy reef growth and support high species diversities. The biological affinities of the reefs include species assemblages typical of the western Indian Ocean and the southeast Asian and central Pacific fauna, and a large variety of habitats and environmental conditions. The reefs of India and Sri Lanka include some of the most used and degraded, as well as some of the most untouched in the region. Although marine protected areas in this region originate from the 1980s, environmental managers rely on an incomplete knowledge of the status and ecology of the reefs. With increasing resource-extraction pressure on these reefs, due to increasing human population and tourism, there is a danger of losing these ecosystems through ignorance and unplanned management. In this chapter we will give a broad overview of the physical and biogeographic influences that shape the reefs of the subcontinent and its islands, and present the major threats to their conservation. The conservation of these reefs may be more limited by their shared cultural and economic institutions so we will also attempt to synthesize the social, economic, and political environment within which rational management will take place, and to identify priority areas for future research and management.

The 1997–1998 El Niño Southern Oscillation (ENSO) event, which elevated Sea Surface Temperatures (SSTs) of tropical oceans by more than 3°C, was one of the most extreme ENSO events in recent history. Such increases in SSTs above the seasonal average can trigger widespread bleaching in coral reefs. This study examined bleaching in three Indian coral reef regions in relation to SSTs using quantitative rapid assessment methods between April and July, 1998. The Gulf of Kutch reefs showed an average of 11% bleached coral with no apparent bleaching-related mortality. In contrast, bleached coral comprised 82% of the coral cover in lagoon reefs of Lakshadweep and 89% of the coral cover in the Gulf of Mannar reefs. Bleaching-related mortality was high – 26% in Lakshadweep and 23% in Mannar. The coral mass mortality may have profound ecological and socio-economic implications and highlights the need for sustained monitoring for coral reef conservation in India.
