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 |
---|---|---|---|---|---|
South African Shelduck Tadorna cana | LC | non-breeding | - | 229-787 individuals | A4i |
Southern Pochard Netta erythrophthalma | LC | non-breeding | - | 326-1,132 individuals | A4i |
Cape Shoveler Spatula smithii | LC | non-breeding | - | 172-404 individuals | A4i |
Great Crested Grebe Podiceps cristatus | LC | non-breeding | - | 62-152 individuals | A4i |
Black-necked Grebe Podiceps nigricollis | LC | non-breeding | - | 68-1,100 individuals | A4i |
Red-knobbed Coot Fulica cristata | LC | non-breeding | - | 18,283-36,000 individuals | A4i |
A4iii Species group - waterbirds | n/a | non-breeding | - | 20,000-49,999 individuals | A4iii |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1998).
