Alstonia sphaerocapitata

Declining

Overview

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

Alstonia sphaerocapitata faces severe pressure from deforestation and habitat conversion throughout its limited range in Southeast Asian lowland forests. Agricultural expansion, particularly oil palm plantations and logging operations, has fragmented its remaining populations. The species' restricted distribution and specific habitat requirements make it particularly vulnerable to ongoing forest clearance in the region.
