Aquilaria crassna

Declining

Overview

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

Aquilaria crassna faces severe population decline primarily due to intensive harvesting for agarwood production, where the resinous heartwood is highly valued in perfume and traditional medicine industries. Illegal logging and over-exploitation have devastated wild populations across its native range in Southeast Asia. Habitat destruction from agricultural expansion and urban development further compounds the species' vulnerability, while slow growth rates limit natural recovery potential.

Threat summary

Habitat

Aquilaria crassna naturally occurs in tropical rainforests and mixed deciduous forests of Southeast Asia, particularly in Cambodia, Laos, Thailand, and Vietnam. The species typically grows in well-drained soils at elevations up to 750 meters, often found in secondary forest areas and forest edges.
