Scientific Foundations

SOCP continues to take a leading role in surveying and monitoring the status of all remaining wild orangutan populations in Sumatra using remote sensing and field surveys to record presence or absence, density estimates, and threats and population trends.

Since its inception in 2000, the Sumatran Orangutan Conservation Programme (SOCP) has been concerned with all aspects of Sumatran orangutan conservation. In order to achieve its ambitious goals, the SOCP strives to be a leading source of information regarding the behavioral ecology and distribution of this Critically Endangered primate. As such, the SOCP, in collaboration with its partner organizations the PanEco Foundation and Yayasan Ekosistem Lestari, regularly conduct orangutan population surveys, in addition to managing numerous monitoring stations, where detailed behavioral and ecological data are currently being collected. Because Sumatran orangutans can be found in various tropical forest habitat types, SOCP maintains monitoring stations in each of these habitat types, including, dryland lowland forest (Ketambe and Sikundur monitoring stations), wet peat swamp forest (Suaq Balimbing monitoring station), and upland forest (Batang Toru monitoring station). The data obtained from these monitoring stations allow conservation biologists to better understand the behavioral variability of the Sumatran orangutan, and as such, allow practitioners to make more informed decisions regarding their future conservation and management.
