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
Carnaby's Black-cockatoo Zanda latirostris	EN	breeding (1970–2008)	20 nests	A1, A3
Western Corella Cacatua pastinator	LC	resident (2007–2008)	present	A2, A3
Regent Parrot Polytelis anthopeplus	LC	resident (2007–2008)	uncommon	A3
Rufous Treecreeper Climacteris rufus	LC	resident (2007–2008)	uncommon	A3
Blue-breasted Fairywren Malurus pulcherrimus	LC	resident (2007–2008)	uncommon	A3
Western Spinebill Acanthorhynchus superciliosus	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 (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
