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	resident (1998–2003)	30–100 pairs	A1
Regent Parrot Polytelis anthopeplus	LC	resident (1998–2008)	uncommon	A3
Mallee Emu-wren Stipiturus mallee	EN	resident (1998–2003)	50–200 pairs	A1, A3
Purple-gaped Honeyeater Lichenostomus cratitius	LC	resident (1998–2003)	50–200 birds	A3
Black-eared Miner Manorina melanotis	EN	resident (1998–2003)	20–40 pairs	A1, A3
Red-lored Whistler Pachycephala rufogularis	VU	resident (1998–2003)	30–100 pairs	A1, 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 (2017) is shown below.
