Data Zone
The site was identified as internationally important for bird conservation in 2021 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 |
|---|---|---|---|---|
| Black-necked Swan Cygnus melancoryphus | LC | resident (2016–2021) | 650–750 birds | A4, B3a |
| Whimbrel Numenius phaeopus | LC | non-breeding (2016–2021) | 500–600 birds | B3a |
| Hudsonian Godwit Limosa haemastica | VU | non-breeding (2016–2021) | 1,874–3,500 birds | A4, B3a |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2021. The most recent assessment (2015) is shown below.
