With a worldwide population estimated at only 9,200, Sumatran orangutans are classified as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Only found on the island of Sumatra in Indonesia, their survival is seriously threatened by habitat loss caused by logging, mining, forest fires and timber clearing for palm oil plantations and human settlements.
