Horsfieldia gracilis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Horsfieldia gracilis faces severe pressure from deforestation and habitat conversion throughout its Southeast Asian range. The species is particularly vulnerable to logging operations and agricultural expansion, as it depends on intact lowland and hill forest ecosystems. Palm oil plantations and urban development have fragmented remaining populations, while the tree's slow growth rate limits natural recovery from disturbance.
Habitat
Horsfieldia gracilis inhabits lowland and hill dipterocarp forests, typically occurring in primary and mature secondary forests up to 800 meters elevation. The species prefers well-drained soils in mixed tropical rainforest communities across peninsular Malaysia, Sumatra, and Borneo.
