Data Zone
The site was identified as internationally important for bird conservation in 2009 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 |
|---|---|---|---|---|
| Red-crested Pochard Netta rufina | LC | breeding (1996–2006) | 250–300 pairs | A4i, B1i |
| Common Pochard Aythya ferina | VU | breeding (2004–2006) | 1,000 pairs | B2 |
| Glossy Ibis Plegadis falcinellus | LC | breeding (1996–2006) | 80–120 pairs | B2 |
| Black-winged Pratincole Glareola nordmanni | NT | breeding (1996–2006) | 10–11 pairs | A1 |
| Slender-billed Gull Larus genei | LC | passage (2006) | 3,000 birds | A4i, B1i |
| Whiskered Tern Chlidonias hybrida | LC | breeding (1996–2006) | 150–250 pairs | B2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2006) is shown below.
