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).
