Abstract
A geographical information system (GIS) was used to map the current distribution of the Sumatran orangutan (Pongo pygmaeus abelii) population in Gunung Leuser National Park (GLNP), North Sumatra. From this, vegetation cover of the orangutan’s distribution was calculated. Vegetation cover and population density estimates within different vegetation types were used to estimate overall population numbers. In addition, the effects of potential land-use changes on the orangutan’s distribution were analyzed using GIS. The land-use scenarios modelled with GIS were: (1) forest loss in and surrounding GLNP; (2) road construction through GLNP; (3) the loss of all low-hill forest in GLNP; and (4) changes in the legal status of park boundaries. This geographical analysis helped guide recommendations for the conservation management of wild orangutans in GLNP.
