Scientific Name: Dypsis mcdonaldiana
Species Authority: Beentje

Assessment Information [top]

Red List Category & Criteria: Endangered B1ab(iii)+2ab(iii) 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 from three widely separated localities (= threat-defined locations) with an extent of occurrence of 3,865 km² and an area of occupancy of 48-499 km². There is continuing decline in the extent and quality of the habitat and hence the species qualifies for listing as Endangered. The status of this species has deteriorated since it was last listed in 2008.
Previously published Red List assessments:
1998 Vulnerable (VU)
1998 Vulnerable (V)
