Data Zone
The site was identified as internationally important for bird conservation in 2011 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 |
|---|---|---|---|---|
| Red-crested Pochard Netta rufina | LC | non-breeding (2009) | 400–800 birds | B1i, C3 |
| Red-crested Pochard Netta rufina | LC | passage (2010) | min 600 birds | B1i, C3 |
| Gadwall Mareca strepera | LC | resident (2010) | min 50 pairs | B2 |
| Gadwall Mareca strepera | LC | winter (2010) | max 1,000 birds | B1i, C3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. The most recent assessment (2007) is shown below.
