Data Zone
The site was identified as internationally important for bird conservation in 2000 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 |
|---|---|---|---|---|
| Northern Shoveler Spatula clypeata | LC | winter (1997) | 106–401 birds | B1i, C3 |
| Northern Pintail Anas acuta | LC | passage (1997) | 100–2,500 birds | B1i, C3 |
| Spotted Crake Porzana porzana | LC | breeding (1991) | 5–10 pairs | B3, C6 |
| Eurasian Spoonbill Platalea leucorodia | LC | passage (1991) | 40–50 birds | B1i, C2 |
| Eurasian Bittern Botaurus stellaris | LC | breeding (1997) | 25–45 pairs | B2, C2, C6 |
| Whiskered Tern Chlidonias hybrida | LC | breeding (1991) | 70 pairs | B2, C6 |
| Black Tern Chlidonias niger | LC | breeding (1991) | 50–200 pairs | C2, C6 |
| Western Marsh-harrier Circus aeruginosus | LC | breeding (1997) | 35–45 pairs | C6 |

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2013) is shown below.
| IBA conservation assessment | |||
|---|---|---|---|
| Year of assessment | State | Pressure | Response |
| 2013 | poor | very high | low |
| Whole site assessed? | State assessed by | Accuracy of information | |

|---|---|---|---|
| Habitat | Quantity (% remaining) | Quality (% carrying capacity) | Result |
| Marine Coastal/Supratidal | good (>90%) | poor (40–69%) | poor |
