Data Zone
The site was identified as internationally important for bird conservation 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 List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Greater Flamingo Phoenicopterus roseus | LC | non-breeding (-) | 1,991–3,522 birds | A4i |
| Lesser Flamingo Phoeniconaias minor | NT | non-breeding (-) | common | A1 |
| Wattled Crane Bugeranus carunculatus | VU | non-breeding (-) | present | A1 |
| Blue Crane Anthropoides paradiseus | VU | non-breeding (-) | present | A1 |
| Southern Bald Ibis Geronticus calvus | NT | non-breeding (-) | 80–100 birds | A1, A4i |
| Black-winged Pratincole Glareola nordmanni | NT | winter (-) | 5,000 birds | A1, A4i |
| Lesser Kestrel Falco naumanni | LC | winter (-) | 1,000–5,000 birds | A1, A4ii |
| A4iii Species group - waterbirds | n/a | non-breeding (-) | min 20,000 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2012) is shown below.
