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 |
|---|---|---|---|---|
| Meller's Duck Anas melleri | EN | resident (1998) | present | A2 |
| Great White Egret Ardea alba | LC | non-breeding (1998) | 678 birds | A4i |
| Madagascar Jacana Actophilornis albinucha | EN | resident (1998) | present | A2 |
| Sickle-billed Vanga Falculea palliata | LC | resident (1998) | present | A3 |
| Sakalava Weaver Ploceus sakalava | LC | resident (1998) | 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.
