The site was identified as internationally important for bird conservation in 2002 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 |
|---|---|---|---|---|
| Eurasian Bittern Botaurus stellaris | LC | passage (2000) | 100 individuals | B2 |
| Common Little Bittern Ixobrychus minutus | LC | passage (2000) | 100 individuals | B2 |
