Data Zone
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') at the site:| Species | Red List1 | Season | Year(s) | Size | IBA criteria |
|---|---|---|---|---|---|
| Meller's Duck Anas melleri | EN | resident | 1998 | present | A2 |
| Great White Egret Ardea alba | LC | non-breeding | 1998 | 678 individuals | 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 |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1999) may differ.
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.
