Sumatran orangutan
The Sumatran orangutan is a great ape native to Sumatra, Indonesia. It is critically endangered and spends most of its life in trees.
Orangutan: A genus of great apes native to the islands of Sumatra and Borneo. The Sumatran orangutan is one of the three living orangutan species.
Orangutan nest: A platform of branches and leaves that an orangutan builds in a tree for resting or sleeping. Individuals usually build fresh nests in trees each night.
Gunung Leuser National Park: A protected area in northern Sumatra that includes extensive rainforest and habitat for Sumatran orangutans. It contains one of the species' major remaining wild populations.
Deforestation in Indonesia: The removal or conversion of forest in Indonesia, driven by activities including agriculture, logging, and infrastructure development. Forest loss in Sumatra removes and divides orangutan habitat.
Bornean orangutan: An orangutan species native to the island of Borneo. It occupies a different island and has distinct population trends and physical traits.
Great ape: A member of the primate family Hominidae, including orangutans, gorillas, chimpanzees, bonobos, and humans. Its family relationships place this species among the great apes.
Orangutan tool use: The use of sticks, leaves, or other objects by orangutans to obtain food or meet other needs. Some populations use tools to extract seeds or access insects.
Leuser Ecosystem: A large forest landscape in northern Sumatra, Indonesia, extending beyond the boundaries of Gunung Leuser National Park. Its connected forests support orangutans and other wildlife beyond the park.
Palm oil: An edible vegetable oil produced from the fruit of oil palm trees. Oil-palm expansion has contributed to forest conversion in orangutan range.
Tapanuli orangutan: An orangutan species native to the Batang Toru region of northern Sumatra. It shares Sumatra with this species but is a separately recognized, highly threatened species.
