The site was identified as important in 2011 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):Species | Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Black Stork Ciconia nigra | LC | passage | 2009 | min 30 individuals | B1i, C2 |
Black Stork Ciconia nigra | LC | breeding | 2009 | 3-5 breeding pairs | B1i, C2 |
Lesser Kestrel Falco naumanni | LC | breeding | 2004 | 70 breeding pairs | C2 |
The current IUCN Red List category (shown above) may differ from that which was valid at the time of IBA criteria assessment (2011).
