The Orangutan Foundation International (OFI) was established in 1986 as a 501 (c)3 organization in the state of California by Dr. Birute Mary Galdikas and a group of concerned scientists and lay people. Since its inception OFI has rescued and returned to the wild over 450 orangutans in Indonesian Borneo and has protected over one million acres of rainforest. OFI has worked with Indonesian government and local communities in Borneo to expand national parks, establish reserves, and buy forest from local people and communities in order to set up local protective forests. OFI supports the longest longitudinal study of any orangutan population in the wild at the Camp Leakey study area in Tanjung Puting National Park, a study that began in 1971 and has been continuous ever since. OFI also repatriated a number of smuggled orangutans back from Taiwan, Thailand, and Malaysia.
