Sumatran tiger (_Panthera tigris sumatrae_) is critically endangered. It is an endemic species to Sumatra. Kerinci Seblat National Park (KSNP) is about 1,4 million hectares and therefore one of the largest remaining tiger habitats in Sumatra. Reliable spatial information on tiger habitats derived from spatial technologies, such as Geographic Information System (GIS), Remote Sensing (RS) and Global Positioning System (GPS), as well as spatial analyses are needed to support KSNP management conserve tigers. The research objectives of this study were to spatially determine Sumatran tiger habitat suitability in the Ipuh-Seblat area located in the Conservation Division Section II of KNSP and to investigate the surrounding area. A tiger habitat suitability model was based on a review of the life requisites habitat of a tiger. These GIS layers included forest cover availability, water availability, prey availability and accessability (elevation and slope). A prey availability GIS layer was obtained from interpolation of prey encounter rates (ERs) derived from forest camera trap survey. Next, a distance to river layer was constructed from a river coverage map, slope and elevation maps were obtained from a contour map and a forest canopy density layer was obtained using a Leaf Area Index (LAI). All of these layers were then overlaid within a GIS and assigned a weight determined from analyzing the distribution of tigers using a Principle Component Analysis (PCA). The habitat suitability models were reclassified into three classes: high; medium; and, low suitability. The results showed that there were 8,31 hectares of low suitability habitat, 1.488,64 hectares of medium habitat and 35.541,92 hectares of high habitat or a proportion of total habitat of 0,02%, 4,36% and 95,64%, respectively. Tiger ERs obtained from camera trap surveys, were then used to validate the habitat suitability model. These results showed that tiger ER was 0 in the low suitable habitat, 2,07 in the medium suitable habitat and 45,44 in the high suitable habitat. The habitat suitability models could be accepted by showing the validation about 95,64% for the high habitat suitability. |
