Data Zone
The site was identified as internationally important for bird conservation in 2006 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 |
|---|---|---|---|---|
| Swan Goose Anser cygnoid | EN | passage (2005) | 3 birds | A1 |
| Dalmatian Pelican Pelecanus crispus | NT | breeding (2006) | 1,000 birds | A1, A4i |
| Great Cormorant Phalacrocorax carbo | LC | breeding (2006) | 3,000 birds | A4i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2014) is shown below.
