Data Zone
The site was identified as internationally important for bird conservation in 1999 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| 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 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1999. The most recent assessment (2017) is shown below.
