The Andulau Forest Reserve in Brunei's Belait District is a prime example of a lowland dipterocarp rainforest ecosystem. Spanning approximately 30,000 hectares, the reserve is characterized by its immense biological diversity and significant stands of the Kapur tree (Dryobalanops aromatica). Since the mid-20th century, it has functioned as a vital hub for botanical research and silvicultural studies focused on sustainable timber management. Geographically, it occupies a transitional zone that combines coastal influences with dense inland rainforest characteristics. The preservation of this area is a key component of Brunei's national strategy to protect its primary forests and secure unique genetic resources. Controlled access via research trails allows for scientific study and ecological monitoring, ensuring that the core areas of the reserve remain undisturbed by human activity.
