National Park in 1992
The park has degraded since 1990, mainly due to illegal logging and fires. Major fires occurred in 1994, and again in 1997, destroying about 12,000ha in the central area of the Park along the Air Hitam Laut River, and about 4,000ha along the Simpang Melaka River. It is estimated that at least 25% of the Park has been affected by illegal logging and subsequent fires. Hunting and capturing of animals and some illegal huts also exist within the reserve.
