Data Zone
The site was identified as internationally important for bird conservation in 2014 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 |
|---|---|---|---|---|
| Australasian Bittern Botaurus poiciloptilus | VU | resident (-) | present | A1 |
| Northern Red-breasted Plover Charadrius aquilonius | LC | resident (2009–2012) | 43–47 pairs | A1, A4i |
| Black-billed Gull Larus bulleri | NT | breeding (-) | present | A1 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2014) is shown below.
