| The Bornean wild cats - A framework for a Wild Cat Action Plan for Sabah | |
| 2010 Full Book | |
The Bornean Wild Cats and Clouded Leopard Project was a three year multi-disciplinary project aimed at addressing the conservation needs of Borneo's wild cats through the merging of pioneering ecological research, conservation awareness and training. This report details the project's preliminary findings and presents a synthesis of the current knowledge regarding the five species of Bornean wild cat, with a particular focus on Sabah populations. The report provides a basic framework for the future development of a wild cat action plan for Sabah. A unique guild of five wild cat species (Sunda clouded leopard, marbled cat, bay cat, flat-headed cat, and leopard cat) inhabit the rainforests of Borneo. Two are considered by the IUCN as Endangered (Bay Cat and Flat Headed Cat), two as Vulnerable (Marbled cat and Sunda Clouded Leopard), yet they remain some of the world's least known wild cats. The Malaysian state of Sabah, in the north of Borneo, holds globally important populations of all four of these threatened felids. Thought to be forest dependant, the presumed primary habitat of Borneo's wild felids is rapidly being lost and/or altered in the region. Whilst direct hunting of these felids and hunting of their prey likely pose an important threat to the continued survival of these wild cats across their range, in Sabah the main threats to wild cats are believed to stem from habitat degradation and fragmentation as a result of previous widespread timber harvesting and conversion for agriculture. The project principal investigators, Andrew Hearn and Joanna Ross, Research Associates of the Global Canopy Programme, in collaboration with Dr. Henry Bernard and Daniel Pamin at the Universiti Malaysia Sabah, conducted wild cat targeted camera trap surveys in five study areas in Sabah, each exposed to different land management practices. These extensive surveys, the most intensive of their kind to date, provide support for the hypothesis that all four threatened species of Bornean wild cat exist at low densities and are in need of immediate conservation attention. Our surveys also support the hypothesis that selectively logged forest can support populations of all four threatened Bornean felid, and thus selectively logged forest is an important resource for these felids in the human modified landscape of contemporary Borneo. In over three years of camera trapping in eastern Sabah the flat-headed cat was only photo captured on a single occasion, highlighting the critical status of this endangered felid in Sabah. A preliminary, yet intensive camera trap survey of an adjacent oil palm plantation provided evidence that of the five Bornean felid species only the leopard cat is able to utilise this highly modified and increasingly widespread environment. Thus, these data provide further, albeit tentative, evidence that forest loss is the principal threat to the continued survival of threatened wild cats in Sabah, and indeed across Borneo. Our research provides the first robust density estimates for any Sunda clouded leopard population. Although preliminary, this research provides the first evidence that recent logging and elevated hunting levels may have a detrimental effect on clouded leopard abundance. Further studies are needed across the Sunda clouded leopard's range, but our initial surveys suggest that no single Conservation Area, Wildlife Reserve or Forest Reserve in Sabah is sufficiently large to support a sustainable and genetically viable clouded leopard population of 500 individuals over the long term. To put this into perspective, we estimate that the extensive forests of the Yayasan Sabah Forest Management Area, one of the largest remaining contiguous areas of lowland Dipterocarp forest in Southeast Asia, at approximately 8,000 km2, may hold around 400 individual clouded leopards. Thus this is the spatial scale at which we will need to act to improve the probability of this species persisting in Sabah. It is therefore imperative that corridors of suitable habitat are maintained between protected areas and commercial forest reserves, and that connectivity is restored between isolated forest blocks to allow gene flow between sub-populations. |
