Author, Andhika Chandra Ariyanto i Mapping of Possible Corridors for Javan Leopard (Panthera pardus ssp. melas) between Gunung Merapi and Gunung Merbabu National Parks, Indonesia ABSTRACT Javan Leopard (Panthera pardus spp. melas) as the remain big cat species in Java Island after the extinction of Javan Tiger in 1980s has been detected occupying the area of Gunung Merapi and Gunung Merbabu National Parks. Its population is threatened by habitat loss, fragmentation habitat, volcanic and wildfire hazard. Unfortunately, the distribution of this species have not been identified. In addition, since those habitats are separated by a main road and highly populated settlements, the research about corridors for the leopards also have not been conducted yet. Considering the facts above, the main objective of this research is to predict and map the possible corridor for Javan Leopard between Gunung Merapi and Gunung Merbabu NPs landscape by using remote sensing and GIS approach. In order to achieve that, Species Distribution Modelling (MaxEnt) was demonstrated to predict the leopards’ distribution and Least Cost Path was applied to figure out the possible paths which connect those two NPs. By using presence-only data of Javan Leopard occurrences, 16 observation points alongside several environmental variables which consist of prey, landcover, NDVI, distance to river, settlement, road/path, elevation, slope, rainfall (annual, maximum, minimum), temperature (maximum, minimum) were deployed into MaxEnt programme. Remotely sensed imagery of Landsat 8 and ArcGIS software were used to the analysis process. The results showed that the total presence of leopards’ distribution was 4,233 ha while 70% of it located within the area of NPs. Landcover, prey distribution, rainfall (maximum and minimum), minimum temperature and NDVI become the most important variables in this model. Meanwhile, least cost path revealed the most likely possible corridor in 6 km route. It characterized by relatively secure track from settlement areas and enough cover along the route. Applying minimum width for strip corridor (1,000 feet), this possible path intersected 6 ha of settlement, 18 ha of farm and 102 ha of agriculture areas of Boyolali District. Become the matrix for Merapi-Merbabu landscape, it plays an important role in creating a corridor to connect those national parks. Moreover, either natural hazards or isolated population issues are plausible to be addressed by developing the corridor.
