Tanjung Puting National Park is a national park in Indonesia located in the southeast part of West Kotawaringin Regency in the Indonesian province of Central Kalimantan (Central Borneo). The nearest main town is the capital of the Regency, Pangkalan Bun. The park is famous for its orangutan conservation. The park is composed of 416,040 hectares of dryland dipterocarp forest, peat swampforest, heath forest, mangrove and costal beach forest, and secondary forest. Despite being a protected National Park, approximately 65% of the park's primary forest is degraded. It is the loss of natural habitat that is the greatest threat to the wildlife. Friends of National Parks Foundation is an Indonesian NGO that has been working to restore the habitat in the Pasalat and Beguruh regions of the park since 1997. It also operates a conservation education centre in Pasalat. Four research centers have been established within the park for the study and rehabilitation of orangutans and other primates. Camp Leakey, founded in 1971 with assistance from the Leakey Foundation, was the first of these centers. It was here where Dr. Birute Galdikas began her career studying the behavior of rescued and orphaned orangutans that were reintroduced into the wild. Her research was highlighted as the cover article of National Geographic in October 1975. Dr. Galdikas is now considered one of the world’s leading experts on orangutan behaviour and is the founder and president of the Orangutan Foundation International.
