Data Zone
The site was identified as internationally important for bird conservation in 2004 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 |
|---|---|---|---|---|
| Ruddy Shelduck Tadorna ferruginea | LC | non-breeding (-) | 310–450 birds | A4i, B1i |
| Eurasian Spoonbill Platalea leucorodia | LC | non-breeding (1994) | 400 birds | A4i, B1i |
| Eurasian Spoonbill Platalea leucorodia | LC | breeding (1989–1998) | 30–45 pairs | B1i, B2 |
| Greater Sandplover Charadrius leschenaultii | LC | breeding (-) | 12 pairs | B2 |
| Slender-billed Gull Larus genei | LC | breeding (-) | 840–1,250 pairs | A4i, B1i |
| Mediterranean Gull Larus melanocephalus | LC | breeding (-) | 1,905–2,250 pairs | B3 |
| Common Gull-billed Tern Gelochelidon nilotica | LC | breeding (-) | 317–400 pairs | A4i, B1i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2016 | very poor | high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |
| yes | habitat | medium | |

|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Wetlands (inland) | moderate (70–90%) | poor (40–69%) | very poor |
| Pressure (threats to the trigger species and/or their habitats) | ||||
|---|---|---|---|---|
| Threat | Timing | Scope | Severity | Result |
| Natural system modifications | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |
