|---|---|---|---|---|
| Audouin's Gull Larus audouinii | VU | winter (2022) | 80 birds | A1 |
| Caspian Tern Hydroprogne caspia | LC | non-breeding (2022) | 234 birds | B3a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2022. The most recent assessment (2022) is shown below.
