Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Haevermans, T.
Reviewer(s): Rajeriarison, C., Labat, J.N., Lowry, P. & Randrianjohany, E. (Madagascar Plants RLA)
Justification:
The extent of occurrence, which encompasses all the known occurrences of the varieties, is about 24,253.2 km². Taking into account the number of susbpopulations for the typical variety and all the others, it is likely that the species is known from less than ten locations. Threats to the species include habitat degradation, fire, habitat clearing for charcoal and collection for horticulture.
Like all the varieties of E. beharensi, the species itself requires further taxonomic studies. The two main subpopulations are separated by a gap and the habitat is highly fragmented. The calculated EOO is at the fringe of VU, but considering the approximations with the localities, the species is given a precautionary rating of VU.
