Shorea teysmanniana

Declining

Overview

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

Shorea teysmanniana faces severe population decline primarily due to extensive logging operations targeting its valuable timber across Borneo's lowland forests. Large-scale conversion of its native dipterocarp forest habitat to oil palm plantations has eliminated vast areas of suitable habitat, while remaining forest fragments are increasingly isolated and degraded. The species' slow growth rate and specific ecological requirements make recovery extremely difficult once populations are reduced.

Threat summary

Habitat

This critically endangered dipterocarp tree is endemic to the lowland tropical rainforests of Borneo, typically occurring in primary and mature secondary forests at elevations below 500 meters. It grows in mixed dipterocarp forest communities on well-drained soils, often associated with other threatened Shorea species in these biodiverse ecosystems.
