Dipterocarpus cornutus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Dipterocarpus cornutus faces severe population decline primarily due to extensive logging for its valuable timber, which is highly prized in construction and furniture making. Rapid deforestation across its native range in Southeast Asia has eliminated most of its lowland forest habitat, while agricultural expansion and palm oil plantations continue to fragment remaining populations. The species' slow growth rate and specific soil requirements make natural regeneration extremely difficult in degraded landscapes.

Threat summary

Habitat

This large emergent tree species inhabits lowland tropical rainforests, typically growing on well-drained soils in primary forest ecosystems. It occurs naturally in mixed dipterocarp forests across Southeast Asia, where it can reach heights of 40-50 meters as a canopy dominant species.
