Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Red Balau faces severe threats from extensive deforestation and habitat conversion throughout its native range in Southeast Asia, particularly due to palm oil plantations, logging operations, and agricultural expansion. The species' slow growth rate and specific habitat requirements make recovery extremely difficult once populations are fragmented or eliminated. Conservation status may vary by region or assessment authority, but the overall trajectory indicates critical population declines.
Key Facts
Habitat & Distribution
Red Balau occurs in tropical lowland dipterocarp forests and mixed rainforests, typically at elevations below 400 meters. The species requires well-drained soils and is often found on hillsides and ridges within primary and mature secondary forest ecosystems.
