Horsfieldia decalvata

Unknown

Overview

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

Horsfieldia decalvata 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 primary forest ecosystems. Palm oil plantations and urban development have fragmented remaining populations, while the tree's slow growth rate limits natural recovery from disturbance.
