Alstonia henryi
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Alstonia henryi faces severe pressure from deforestation and habitat conversion throughout its range in Southeast Asia. The species is particularly vulnerable to logging operations targeting its preferred lowland and hill forest habitats for timber extraction and agricultural expansion. Urban development and infrastructure projects have further fragmented remaining forest patches, isolating populations and reducing genetic diversity.
Habitat
Alstonia henryi inhabits tropical lowland and hill forests, typically found at elevations up to 800 meters. The species prefers primary and secondary forest environments with well-drained soils and partial canopy cover.
