A field survey for the grey-shanked douc langur
Ha Thang Long
The grey-shanked Douc langur (Pygathrix cinerea) is endemic to Vietnam and occurs in a restricted range in the central coastal region and the central highlands of Vietnam (Quang Nam, Quang Ngai, Binh Dinh, Kon Tum and Gia Lai). The species has been identified as one of the world’s 25 most endangered primates and the remaining population has been estimated to be as low as about 600 individuals. The species suffers from high hunting pressure for food and traditional medicine and from habitat loss. Vietnam’s primary forests are still declining and forests get increasingly fragmented through logging and conversion to agricultural land. Gia Lai Province still holds several populations of the grey-shanked Douc langurs in several protected areas. The team will conduct surveys in two protected areas and the unprotected land separating these areas in order to investigate the possibility of creating a corridor and developing appropriate recommendations for the species' conservation in this area.
