Assessment Information [top]

Red List Category & Criteria: Vulnerable D1 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., Baker, W.J. & Beentje, H.J.
Justification:
Known only from three locations near the Bay of Antongil area but the species is abundant (300 individuals estimated) and its occurrence sites are all within protected areas where forest exploitation is not allowed. Hence although the range area is small (extent of occurrence of 901 km² and area of occupancy of 216 km²) as there are no threats at present to the species, it is listed as Vulnerable on the basis of the small population size. Should the population be found to be larger than 1,000 mature individuals then a reassessment would be required.
History:
1998 Vulnerable
1997 Vulnerable (Walter and Gillett 1998)
