Data Zone
The site was identified as internationally important for bird conservation in 2006 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 |
|---|---|---|---|---|
| White-headed Duck Oxyura leucocephala | EN | passage (2000–2005) | 10–100 adults | A1, A4i |
| Greylag Goose Anser anser | LC | passage (2000–2005) | 500–10,000 adults | A4i |
| Ferruginous Duck Aythya nyroca | NT | breeding (2000–2006) | 26–64 adults | A1 |
| Glossy Ibis Plegadis falcinellus | LC | breeding (2005–2008) | 88–999 adults | A4i |
| Great White Pelican Pelecanus onocrotalus | LC | breeding (2005) | 80–300 adults | A4i |
| Pygmy Cormorant Microcarbo pygmaeus | LC | breeding (2005–2006) | 94–3,000 adults | A4i |
| Great Cormorant Phalacrocorax carbo | LC | breeding (2005–2006) | 200–2,000 adults | A4i |
| Little Tern Sternula albifrons | LC | breeding (2008) | 324 adults | A4i |
| A4iii Species group - waterbirds | n/a | passage (2000–2005) | 50,000 birds | A4iii |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2006. The most recent assessment (2017) is shown below.
