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 |
|---|---|---|---|---|
| Malleefowl Leipoa ocellata | VU | breeding (1975–2008) | frequent | A1 |
| Mallee Emu-wren Stipiturus mallee | EN | breeding (2005) | 10 pairs | A1, A2, A3 |
| Purple-gaped Honeyeater Lichenostomus cratitius | LC | resident (1998–2008) | frequent | 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.

| Threat | Timing | Scope | Severity | Result |
| Invasive and other problematic species and genes | happening now | most of population/area (50–90%) | moderate decline (10–30% over 3 generations) | high |

| Agricultural expansion and intensification | past (and unlikely to return) and no longer limiting | few individuals/small area (<10%) | no or slight decline (<1% over 3 generations) | low |
