It is estimated that their population has decreased 30% in the last 30 years but the truth is that no accurate population count has ever been made and no one is even sure how to carry one out.
Combine this lack of scientific knowledge, with the lack of conservation effort and its ecological importance, it becomes clear that the sun bear is a neglected tropical rainforest species in Borneo.

The Malayan sun bear (Helarctos malayanus) is threatened throughout its natural home range in the tropical rainforests of Southeast Asia, from India to China to the islands of Indonesia.

During a 27 month field study, [researchers] learned that Malayan sun bears have large home ranges, move considerably in search of food, and use old and large trees as bedding and denning sites. Food apparently varies significantly throughout the year, and in some areas, bears may starve due to natural fluctuations in food abundance of food.

Because there is so little that scientists really know about sun bears, it is difficult to implement conservation plans. However, in 2007, the IUCN classified the sun bear as vulnerable. Habitat loss, poaching for the illegal trade in bear parts, legal killing of “nuisance bears”, and conflicts with humans are exerting significant impacts throughout the bears’ range and threaten its survival.

Today, the sun bear exists in forests throughout Southeast Asia from northern Burma and Bangladesh, south and east across Laos, Cambodia, Vietnam, and Thailand, and south to Malaysia and the islands of Sumatra and Borneo. Deforestation, often caused by the palm oil and rubber industries, is destroying a large portion of their range, particularly in the northern and western areas.
