| Sumatran Tiger Conservation in Human-Dominated Landscapes | |
| 2007 Conference Proceeding | |
Habitat loss and an increasingly pervasive human population continue to drive the decline of remaining Sumatran tiger (_Panthera tigris sumatrae_) populations. Much of Sumatra's landscape is now dominated by a matrix of oil palm, degraded forest and rural settlement. Our objective was to identify the anthropogenic and environmental factors associated with species persistence in this environment. Repeated detection/non-detection surveys of 100 survey cells across two study sites, totaling 1200km2, recorded 25 medium/large mammal species from 2400 hours of search effort and 2000 camera trap-nights. We present field methods and a statistical framework able to identify key landscape factors associated with the probability of species occurrence in this context. Preliminary results from the principle study site indicate that mammalian diversity differed between major habitat classes with highest overall species richness recorded in areas dominated by degraded forest, rather than oil palm or rural settlements. In the principal study site tigers used more remote forest habitats characterized by low levels of human activity. Our results provide a basis for collaborative Sumatran-wide surveys of tiger and prey species distributions and associated threats, which will underpin future landscape conservation measures. |
