The rainforests of Sumatra are under massive threat of deforestation, as vast areas are logged for timber and to make way for palm plantations. It is estimated that Indonesia has now lost around 72% of its original rainforest cover and the scale of deforestation is continuing at an alarming rate (6). As well as affecting titan arum numbers directly, the loss of habitat is also endangering species such as the rhinoceros hornbill (Buceros rhinoceros), which is an important seed distributor (6).
