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'):| Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
|---|---|---|---|---|---|
| Little Grebe Tachybaptus ruficollis | LC | non-breeding | 1997 | 1,500 individuals | A4i |
| Red-knobbed Coot Fulica cristata | LC | non-breeding | 1991 | 19,400 individuals | A4i |
| African Spoonbill Platalea alba | LC | non-breeding | 1997 | 412 individuals | A4i |
| Grey-crested Helmetshrike Prionops poliolophus | NT | resident | 1999 | present | A1, A2 |
| Basra Reed-warbler Acrocephalus griseldis | EN | non-breeding | - | present | A1 |
| A4iii Species group - waterbirds | n/a | non-breeding | - | 20,000 individuals | A4iii |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1999).
