Overview

Dipterocarpus kunstleri is a species of tree in the family Dipterocarpaceae, native to Southeast Asia.

Dipterocarpus kunstleri faces severe population decline primarily due to extensive deforestation and habitat conversion for palm oil plantations and agricultural development across its native range in Peninsular Malaysia and southern Thailand. The species' large size and valuable timber make it a target for selective logging, while its slow growth and specific habitat requirements limit natural regeneration in fragmented landscapes.
