Pterospermum fuscum

Declining

Overview

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

Pterospermum fuscum faces severe pressure from deforestation and agricultural expansion across its Southeast Asian range, particularly in lowland areas where commercial logging and palm oil plantations have fragmented its forest habitat. The species' limited distribution and specific habitat requirements make it highly vulnerable to continued forest conversion, while its slow growth rate as a canopy tree limits natural recovery potential.

Threat summary

Habitat

This tropical tree species inhabits lowland and hill dipterocarp forests, typically occurring in primary and mature secondary forests at elevations up to 800 meters. It prefers well-drained soils in mixed dipterocarp communities where it can reach the forest canopy.

Frequently asked questions

Why is Pterospermum fuscum classified as Endangered?
Pterospermum fuscum is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Pterospermum fuscum faces severe pressure from deforestation and agricultural expansion across its Southeast Asian range, particularly in lowland areas where commercial logging and palm oil plantations have fragmented its forest habitat. The species' limited distribution and specific habitat requirements make it highly vulnerable to continued forest conversion, while its slow growth rate as a canopy tree limits natural recovery potential.
Where does Pterospermum fuscum live?
Pterospermum fuscum occurs in Indonesia, and Malaysia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pterospermum fuscum?
The main threats to Pterospermum fuscum are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
