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 |
|---|---|---|---|---|
| Eastern Bristlebird Dasyornis brachypterus | VU | resident (1992–1996) | 810 birds | A1, A2, A3 |
| Pilotbird Pycnoptilus floccosus | VU | resident (1998–2008) | uncommon | A2 |
| Rockwarbler Origma solitaria | LC | resident (1990–2008) | 20 birds | A2, A3 |
Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2020) is shown below.
