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 |
|---|---|---|---|---|
| Corncrake Crex crex | LC | breeding (2006–2009) | 80–100 males | C1 |
| White Stork Ciconia ciconia | LC | breeding (1995–2003) | 220 pairs | C6 |
| Lesser Spotted Eagle Clanga pomarina | LC | breeding (2004–2009) | 45–50 pairs | C6 |
| White-tailed Sea-eagle Haliaeetus albicilla | LC | breeding (2008–2009) | 6–7 pairs | C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2008) is shown below.
