Alstonia penangiana

Unknown

Overview

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

Alstonia penangiana faces severe population decline primarily due to extensive deforestation and habitat conversion throughout its native range in Peninsular Malaysia and southern Thailand. The species' large timber value has made it a target for selective logging, while rapid urban development and agricultural expansion have fragmented remaining forest patches. Climate change compounds these pressures by altering rainfall patterns essential for this moisture-dependent tree species.

Threat summary

Habitat

This large canopy tree inhabits lowland tropical rainforests and secondary forests up to 300 meters elevation, preferring well-drained soils in areas with consistent moisture. It occurs naturally in both primary forest reserves and disturbed forest edges throughout Peninsular Malaysia and adjacent regions of southern Thailand.
