Data Zone
The site was identified as internationally important for bird conservation in 2007 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 |
|---|---|---|---|---|
| Pygmy Cormorant Microcarbo pygmaeus | LC | breeding (1990–2006) | 350–450 breeding pairs | C2, C6 |
| Little Tern Sternula albifrons | LC | passage (1990–2006) | 70–140 individuals | C6 |
| European Roller Coracias garrulus | LC | breeding (1990–2006) | 16–20 breeding pairs | C1 |
| A4iii Species group - waterbirds | n/a | passage (1990–2006) | 20,000 individuals | C4 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2016) is shown below.
