Assessment Information [top]

Red List Category & Criteria: Endangered A4ad ver 3.1
Year Published: 2012

There is likely to have been a significant population reduction in this species because it is so highly targeted for charcoal burning. Given known reduction figures in some areas and given the generation length of about 30 years, it seems reasonable to list this species as Endangered under criterion A4 based on direct observation of the decline in numbers of mature individuals as a result of exploitation and the expectation that this will continue at the same or an even higher rate into the foreseeable future.

Use and Trade [top]

Use and Trade: The timber of this species is used for construction purposes. It is also highly sought after for charcoal burning as it is one of the best species for this.

Threats [top]

Major Threat(s): This species is targeted for charcoal burning as it is one of the best trees for this. Trees are also logged for their timber. There is also loss of habitat across the species' range because of expanding agricultural activities.

Conservation Actions [top]

Conservation Actions: The species occurs in some protected areas, but  it is so highly sought after that this may offer the species little protection.

No seeds have been collected and stored by a seed bank as a method of ex situ conservation.
