Data Zone
The site was identified as important in 2010 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):| Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
|---|---|---|---|---|---|
| Corncrake Crex crex | LC | breeding | 2006-2009 | 40-70 males | C1 |
| Common Little Bittern Ixobrychus minutus | LC | breeding | 2006-2009 | 5-15 breeding pairs | C6 |
| Mediterranean Gull Larus melanocephalus | LC | breeding | 2007-2009 | 10-15 breeding pairs | C6 |
| Little Tern Sternula albifrons | LC | breeding | 2007-2009 | 420-540 breeding pairs | C6 |
| Common Tern Sterna hirundo | LC | breeding | 2007-2009 | 1,400-1,700 breeding pairs | C6 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2010).
