Developing management strategies for Sumatran tigers (Panthera tigris sumatrae) utilizing GIS to estimate distribution and numbers
Conference Proceeding
Human-caused factors have resulted in a decline of the Sumatran tiger. It has been suggested that the five national parks offer the best chance of saving Sumatran tigers. Tiger numbers of these protected areas were estimated using GIS to map potential habitat. Vegetation types were assigned one of three home range estimates based on their suitability as tiger habitat. Our results indicate that if Sumatran tigers are confined to national parks they may require intensive management, regardless of the accuracy of the population estimates. Management efforts should focus on improving the understanding of the biology of Sumatran tigers and on maintaining tracts of forest that will harbor populations larger than 100 individuals. These forest tracts can be maintained by reducing the fragmentation of the parks due to roads, and by incorporating adjacent areas of lesser conservation status into the tiger management plans of the five national parks.
