| description | Extensive areas of the world’s tropical forests have been, and continue to be, disturbed as a result of selective timber extraction. While such anthropogenic disturbance typically results in the loss of biodiversity, many species persist, and their conservation in production landscapes could be enhanced by a greater understanding of how biodiversity responds to forest management practices. We conducted intensive camera trap surveys of eight protected forest areas in Sabah, Malaysian Borneo, and developed estimates of Sunda clouded leopard population density from spatially explicit capture-recapture analyses of detection data to investigate how their abundance varies across the landscape and in response to anthropogenic disturbance. Estimates of population density from six forest areas ranged from 1.39 to 3.10 individuals per 100 km2. Our study provides the first evidence that Sunda clouded leopard population density is negatively impacted by hunting pressure and forest fragmentation, and that among selectively logged forests, time since logging is positively associated with abundance. We argue that these negative anthropogenic impacts could be mitigated with improved logging practices, such as by reducing the access of poachers by effective gating and destruction of road access points, and by the deployment of anti-poaching patrols. By calculating a weighted mean population density estimate from estimates developed in this paper and from the literature, and by extrapolating this value to an estimate of current available habitat, we estimated there are 754 (95% posterior Interval 325–1337) Sunda clouded leopard individuals in Sabah. |
