    To provide an estimate of home range sizes and the population densities of Tarsius bancanus saltator on Belitung Island and to discuss the implications of this information on its conservation status, a study was conducted in Gunung Tajam, Belitung Island, Indonesia. There are two available different habitat types observed in this study, i.e: study site HI and H2. Twenty two individuals were captured within 42 captures using mist-nets. All captured tarsiers were radio-tracked to estimate their home range sizes. Home range sizes of Belitung Island tarsier vary from 1.59 to 3.25 ha for females and 4.18 to 11.98 ha for males in both study sites. The population density of tarsiers in the first study site was estimated at 19-20 animals/km2 and in the second study site up to 46-47 animals/km2. Compared to other species, the population densities of Belitung tarsier were lower than those inhabit Sulawesi and the Philippines. Considering the high rate of deforestation in protected areas in other regions of Indonesia and that there is no protected area on Belitung Island, the population of the tarsier on Belitung Island also faces major threat of habitat loss and fragmentation. Based on the area of occupancy, known population that exist only in 9 locations and projected population decline in the future, conservation status of the Belitung tarsier should be upgraded from data deficient to vulnerable.
