Assessment Information [top]

Red List Category & Criteria: Critically Endangered C2a(i); D ver 3.1
Year Published: 2012
Date Assessed: 2010-12-17
Assessor(s): Rakotoarinivo, M. & Dransfield, J.
Reviewer(s): Baker, W.J., Beentje, H.J. & Bachman, S.
Known from two severely fragmented areas in the centre of Madagascar. Fewer than 40 mature trees are estimated to exist in the wild. There is continuing decline due to various threats hence the species qualifies for listing as Critically Endangered. If the population is found to be much larger, it would probably qualify as Endangered under the restricted range criteria. This species is in need of conservation attention given the small size of the population and the increasing threats to the remaining habitat, none of which is currently protected.
