epa05550212 Sumatran Orangutan Conservation Program (SOCP) staff holds an orangutan that just arrived in the Jantho Reintroduction and Quarantine Station in Jantho, Aceh Besar, Indonesia 21 September 2016. The station is a training centre for confiscated orangutans that were raised by man as pets and had become unfamiliar with living in the wild. A the center the the orangutans are trained to be finally be release into wild and able to survive on their own. A major problem is that orangutans that for a long time lived close to humans are incapable of feeding themselves and building nests. The species is listed on Appendix 1 of the Convention on International Trade in Endangered Species (CITES), under which animals smuggled out of their natural range country and confiscated should whenever possible be repatriated and returned to the wild. Orangutans (pongo abelii, pygmaeus) are rare and protected primates living in the forest zones of Sumatra and Kalimantan. Based on data from the Orangutan Information Center, their population is estimated at less than 30,000 in the two regions, with wild orangutans in Sumatra numbering between 6,500 and 7,500, and in Kalimantan between 12,000 and 13,000.
