The site was identified as internationally important for bird conservation in 2008 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 |
---|---|---|---|---|
Whooper Swan Cygnus cygnus | LC | winter (2003–2006) | 66–634 birds | B1i |
Mallard Anas platyrhynchos | LC | winter (2003–2006) | 68,240–80,000 birds | A4i, B1i |
Glossy Ibis Plegadis falcinellus | LC | breeding (2004–2006) | 1,050 pairs | A4i, B1i, B2 |
Black-crowned Night Heron Nycticorax nycticorax | LC | breeding (2006) | 200 pairs | B2 |
Squacco Heron Ardeola ralloides | LC | breeding (2004–2006) | 50–55 pairs | B2 |
Little Egret Egretta garzetta | LC | breeding (2006) | 280–300 pairs | B1i |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2006) is shown below.
