Data Zone
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 |
|---|---|---|---|---|
| Little Tern Sternula albifrons | LC | breeding (2000) | 309 pairs | A4i, B1i, B2, C2 |
| Little Tern Sternula albifrons | LC | breeding (2006) | 369 pairs | A4i, B1i, B2, C2 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.
