Species Authority: Thouars

Assessment Information [top]

Red List Category & Criteria: Endangered A3cd ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Hong-Wa, C.
Reviewer(s): Birkinshaw, C., Lowry, P.P. & Rajeriarison, C. (Madagascar Plants RLA)
Justification:
This species has a very large extent of occurrence and area of occupancy and is known from a number of locations. However, the selective exploitation of this species for construction (due to its highly resistant qualities) is a major threat likely to lead to a population reduction of 80% in the future.

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: Low- elevation evergreen forest, and littoral forest.
Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat loss because of selective exploitation of timber for construction. The bark is also used for medicinal purposes. Also threatened by fire, cyclone, invasive alien species and poor regeneration. The decline may also be because of the increasing rarity of vertebrate dispersers (birds and lemurs). The species is not tolerant to disturbance.
