Goniothalamus macrocalyx

Unknown

Overview

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

Goniothalamus macrocalyx 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, continues to fragment and destroy the primary forest habitats essential for this species' survival. The species' restricted distribution makes it particularly vulnerable to localized habitat loss, with remaining populations increasingly isolated in forest fragments.

Threat summary

Habitat

Goniothalamus macrocalyx inhabits lowland tropical rainforests, typically found in primary and mature secondary forests at elevations below 500 meters. The species requires dense canopy cover and thrives in the understory of humid, well-drained forest environments with rich organic soils.
