The site was identified as internationally important for bird conservation in 2007 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 |
|---|---|---|---|---|
| Mew Gull Larus canus | LC | breeding (1998) | 18,463 pairs | A4i, B1i, B2, C3 |
| A4iii Species group - waterbirds | n/a | breeding (1998) | 18,639 pairs | A4iii, C4 |
