The site was identified as important in 1999 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Giant Coua Coua gigas | LC | resident | 1996 | present | A3 |
Running Coua Coua cursor | LC | resident | 1996 | present | A2, A3 |
Olive-capped Coua Coua olivaceiceps | LC | resident | 1996 | present | A3 |
Archbold's Newtonia Newtonia archboldi | LC | resident | 1996 | present | A2, A3 |
Lafresnaye's Vanga Xenopirostris xenopirostris | NT | resident | 1996 | present | A2, A3 |
Sickle-billed Vanga Falculea palliata | LC | resident | 1996 | present | A3 |
Thamnornis Thamnornis chloropetoides | LC | resident | 1996 | present | A2, A3 |
Sakalava Weaver Ploceus sakalava | LC | resident | 1996 | present | A3 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1999).
