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 IBA criteria.
Populations meeting IBA criteria ('key species') at the site:| Species | Red List | Season (year/s of estimate) | Size | IBA criteria |
|---|---|---|---|---|
| Osprey Pandion haliaetus | LC | breeding (1995–2003) | 1–2 breeding pairs | C6 |
| White-tailed Sea-eagle Haliaeetus albicilla | LC | breeding (1990–2003) | 5–7 breeding pairs | C6 |
| Red Kite Milvus milvus | LC | breeding (1990–2003) | 10–14 breeding pairs | C1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2009) is shown below.
