Data Zone
The site was identified as important in 1998 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 |
|---|---|---|---|---|---|
| Corncrake Crex crex | LC | winter | - | present | A1 |
| Southern Banded Snake-eagle Circaetus fasciolatus | NT | resident | 1998 | present | A3 |
| Mangrove Kingfisher Halcyon senegaloides | LC | resident | 1998 | present | A3 |
| Gorgeous Bush-shrike Telophorus viridis | LC | resident | 1998 | present | A3 |
| Black-bellied Starling Notopholia corusca | LC | resident | 1998 | present | A3 |
| Spotted Ground-thrush Geokichla guttata | VU | non-breeding | - | present | A1 |
| Mouse-coloured Sunbird Cyanomitra verreauxii | LC | resident | 1998 | present | A3 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1998).
