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') at the site:Species | Red List1 | Season | Year(s) | Size | IBA criteria |
---|---|---|---|---|---|
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 Bushshrike 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 |
1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1998) may differ.
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2014) is shown below.
