Data Zone
The site was identified as internationally important for bird conservation in 2009 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 |
|---|---|---|---|---|
| Blue-billed Duck Oxyura australis | LC | breeding (1981–2008) | 102 birds | A1 |
| Australasian Bittern Botaurus poiciloptilus | VU | breeding (1981–2008) | 8 birds | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2019) is shown below.
