This primate lives in primary or secondary semi-deciduous monsoon forests and tropical evergreen forests. Occupying only the upper canopy, these gibbons rarely, if ever, come down to the forest floor. Found in the tropical rainforests of southern  and southeast Asia in the countries of China, Myanmar, Thailand, Malaysia and Indonesia – including Sumatra. Rapid loss of habitat poses the biggest threat to Gibbons, placing their future in great peril. With breathtaking speed the forests of Southeast Asia are being cut down leaving an ever smaller area in which to live.
