Research Objectives: Since its inception in 2001, 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 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 long-term monitoring stations in each of these habitat types, including, dry lowland forest (Sikundur, 2013-ongoing), wet peat swamp forest (Suaq Balimbing, 1994-1998, 2005-ongoing), and upland forest (Batang Toru, 2006-ongoing). The information obtained from the long-term work at these monitoring stations allows conservation biologists to better understand the habitat and behavioral variability of Sumatran orangutans, and as such, helps practitioners to make more informed decisions regarding their future conservation and management of the species.

Field Positions and Volunteers: We at SOCP are always looking for motivated researchers and volunteers to come to Indonesia and participate at one of our three long-term monitoring stations in the Sumatran provinces of Aceh and North Sumatra. Specific positions sought will be regularly posted on the Primate Info Net - Positions Available page (; however, we also invite unsolicited field researchers and volunteers to contact us directly. While we focus our monitoring activities on orangutans, we are always open to have researchers who are interested in other aspects of Sumatran flora and fauna.

Species Studied: Pongo abelii (Sumatran orangutan)

Other Species at Site: Hylobates agilis (agile gibbon), Hylobates lar (lar gibbon), Macaca fascicularis (long-tailed macaque), Macaca nemestrina (pigtail macaque), Nycticebus coucang (slow loris), Presbytis melalophos (Sumatran surili), Presbytis thomasi (Thomas's langur), Symphalangus syndactylus (siamang), Trachypithecus cristatus (silvery lutung)

Publications: Please see the SOCP website

Comments: Long-term behavioral (orangutan only), climatological (rainfall, relative humidity, and temperature), and phenological (flowers, leaves, and fruit) data are collected at each of our three monitoring stations.
