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
Painted Honeyeater Grantiella picta	LC	resident (1991–1997)	uncommon	A1
Diamond Firetail Stagonopleura guttata	VU	resident (1991–2008)	frequent	A1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Natural system modifications	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Energy production and mining	likely in short term (<4 years)	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Some limited conservation initiatives are in place	medium
