Range DescriptionFound in Indonesia and Philippines. In Indonesia it is restricted to Sumatera where there are three subpopulations: Aceh, Tapanuli and Kerinici. The largest is in Aceh in the north. In the 1960s it was estimated to cover an area of about 200,000 ha: this has since declined due to logging and forest conversion (Hardayanto 2001, Siregar and Hattemer 1999). The Tapanuli subpopulation covered about 3,500 ha in the early 1990s. It too has significantly declined due to logging. The Kerinici subpopulation is estimated to cover less than 500 ha. Each subpopulation is now severely fragmented (Hardayanto 2001). The total current area of occupancy is less than 130,000 ha (Siregar and Hattemer 1999). In the Philippines it is restricted to Paragpagan/Kabilayan Barangay Pinagturilan, Sta. Cruz, Occidental Mindoro and Sta Cruz, Masinloc, Candelaria, Zambales. Both localities are small and degraded (Razal 2005).
