摘要：Hasselt’s litter frogs (Leptobrachium hasseltii Tschudi 1838) is a wide spread species in Java and Sumatra, however, the specific distribution map for this species is not available. The purpose of this study is to identify the distribution of hasselt’s litter frogs in Java and to examine the suitability map of the species by using maximum entropy method. We used presence data and environment variables consist of elevation, slope, NDVI (Normalized Difference Vegetation Index), distance from the river, temperature, precipitation, and land cover types to develop the distribution model of this species. Hasselt’s litter frogs in Java depends on forested area with a wide range of elevation (lowland to mountain forests), moderate slope, temperature between 20-21oC and rainfall over 2500 mm/year. The highest number of frogs are found in secondary forest land cover, NDVI values between 0.8 to 0.9 and relatively close to the river. Habitat model constructed are robust with AUC (Area Under Curve) value of 0.951. Environmental variables that most affectted habitat for hasselt’s litter frog are land cover, temperature, and slope.
