Horsfieldia atjehensis

Unknown

Overview

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

Horsfieldia atjehensis faces severe pressure from deforestation and habitat conversion throughout its limited range in northern Sumatra. The species is particularly vulnerable due to its restriction to lowland and hill forests below 1,000 meters elevation, areas that experience the highest rates of palm oil plantation development and logging activities. Agricultural expansion and infrastructure development continue to fragment remaining forest patches, isolating populations and reducing genetic diversity.
