Data Zone
The site was identified as internationally important for bird conservation in 2010 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 |
|---|---|---|---|---|
| Whooper Swan Cygnus cygnus | LC | breeding (2007–2009) | 2–3 pairs | C6 |
| Corncrake Crex crex | LC | breeding (2009) | 600–800 males | C1, C6 |
| Common Crane Grus grus | LC | breeding (2004–2009) | 300–400 pairs | C6 |
| Black Stork Ciconia nigra | LC | breeding (2004–2009) | 15–20 pairs | C6 |
| White Stork Ciconia ciconia | LC | breeding (2008–2009) | 800–900 pairs | C6 |
| Lesser Spotted Eagle Clanga pomarina | LC | breeding (1995–2003) | 90–110 pairs | C6 |
| Western Marsh-harrier Circus aeruginosus | LC | breeding (2004–2009) | 60–80 pairs | C6 |
| Montagu's Harrier Circus pygargus | LC | breeding (2004–2009) | 15–30 pairs | C6 |
