Data Zone
The site was identified as internationally important for bird conservation in 2001 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 |
|---|---|---|---|---|
| Marbled Duck Marmaronetta angustirostris | NT | breeding (-) | 60 pairs | A1, A4i |
| Marbled Duck Marmaronetta angustirostris | NT | winter (-) | 150–200 birds | A1, A4i |
| Ferruginous Duck Aythya nyroca | NT | winter (-) | common | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2009) is shown below.
