Carallia hulstijnii

Unknown

Overview

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

Carallia hulstijnii faces severe threats from rapid deforestation and habitat conversion in its limited range within Indonesian Borneo. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, with logging activities and agricultural expansion fragmenting its remaining forest habitat. Palm oil plantation development poses an ongoing threat to the lowland forests where this endemic tree species occurs.
