Data Zone
The site was identified as internationally important for bird conservation in 2004 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 (2000) | 3–5 pairs | C6 |
| Little Tern Sternula albifrons | LC | breeding (2000) | 3 pairs | C6 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2013) is shown below.
