Overview

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

Angkalanthus oligophylla faces severe pressure from deforestation and agricultural expansion across its limited range in Southeast Asian lowland forests. Mining activities and infrastructure development have fragmented remaining populations, while the species' narrow ecological requirements make it particularly vulnerable to habitat degradation. Climate change poses an additional threat through altered precipitation patterns affecting the humid forest conditions this species requires.

Threat summary

Habitat

This species inhabits humid lowland tropical forests, typically found in understory environments with dense canopy cover and consistent moisture levels. It shows preference for primary forest areas with minimal human disturbance, occurring at elevations below 500 meters.
