This species is Vulnerable within its natural growth range and may move into the Endangered classification if current trends persist. These trends include decreasing population due to over-exploitation, extensive destruction of natural habitat, uncertain future security due to severe depletion, and threat from serious adverse environmental factors currently existing in growth range and which has the potential to drastically reduce species population
Distribution Overview
This species is one of three in the Parashorea genus that are reported to occur in the Malay Peninsula. The other two are P. densiflora and P. globosa . Their distribution is restricted and they are comparatively rare.

Exposure darkens the color. The color is intermediate between those of White meranti and Light red meranti
Sapwood Color
The natural color of the sapwood is light yellow brown, but it is often darker in color than the heartwood because of staining from severe fungal attack. The sapwood is clearly differentiated in green and air-dry timber, but is less so in kiln-dry lumber. Width is about 2 inches (5 cm)

Parashorea genus is reported to produce very large trees, some of which mature to a height of 200 feet (60 m) and a trunk diameter of 36 to 60 inches (90 to 150 cm) or more overly large buttresses. They develop straight, well-formed stems that are often clear of branches to 100 feet (30 m).
