Danum Valley Conservation Area is a 438 square kilometres tract of relatively undisturbed lowland dipterocarp forest in Sabah, Malaysia. The area holds unique status in the sense that before it became a conservation area there were no human settlements within the area, meaning that hunting, logging and other human interference was non-existent, making the area almost unique. It is managed by Yayasan Sabah for conservation, research, education, and habitat restoration training purposes.
Danum Valley Conservation Area is dominated by dipterocarp tress, with the canopy reaching a height of over 70 metres in some places. Some 90% of the Conservation Area is classified as dipterocarp forest, with the remaining 10% being low canopy, sub-montane forest mainly found on Mount Danum in the heart of the Conservation Area.
