Large mammal use of protected and community-managed lands in a biodiversity hotspot

In large parts of the biodiversity-rich tropics, various forest governance regimes often coexist, ranging from governmental administration to highly decentralized community management. Two common forms of such governance are protected areas, and community lands open to limited resource extraction. We studied wildlife occurrences in the north-east Indian state of Arunachal Pradesh, where the Eaglenest Wildlife Sanctuary (EWS) is situated adjacent to community lands governed by the Bugun and Sherdukpen tribes. We conducted transect-based mammal sign surveys and camera trapping for mammals (>0.5 kg), and interviewed members of the resident tribes to understand their hunting practices and causes of wildlife declines. Interviews indicated hunting-mediated declines in the abundances of mammals such as the tiger Panthera tigris, gaur Bos gaurus and river otters Lutrogale and Aonyx species. Larger species such as B. gaurus were much more abundant within EWS than outside of it. Community-mana...
