Tristaniopsis pontianensis

Unknown

Overview

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

Tristaniopsis pontianensis faces severe pressure from rapid deforestation and land conversion for palm oil plantations across its native range in Peninsular Malaysia and southern Thailand. The species' restricted distribution in lowland and hill dipterocarp forests makes it particularly vulnerable to habitat fragmentation, as remaining populations become increasingly isolated. Logging activities targeting valuable timber species in these forests further degrade the ecosystem structure that this endemic tree depends upon.

Threat summary

Habitat

This endemic tree species occurs in primary and secondary lowland dipterocarp forests and hill forests up to 800 meters elevation. It is typically found in well-drained soils along ridges and slopes within the mixed dipterocarp forest ecosystem of Peninsular Malaysia and southern Thailand.
