The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Carnaby's Black-cockatoo Zanda latirostris	EN	non-breeding	2003-2006	4,500-15,000 individuals	A1, A3
Western Corella Cacatua pastinator	LC	resident	1998-2008	uncommon	A2, A3
Red-capped Parrot Purpureicephalus spurius	LC	resident	1998-2008	uncommon	A3
Western Rosella Platycercus icterotis	LC	resident	1998-2008	uncommon	A3
Western Spinebill Acanthorhynchus superciliosus	LC	resident	1998-2008	uncommon	A3
Western Thornbill Acanthiza inornata	LC	resident	1998-2008	uncommon	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

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
Shrubland	very poor (< 40%)	poor (40-69%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happening now	majority/most of area/population (50-90%)	very rapid to severe deterioration	very high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Agricultural expansion and intensification	likely in long term (beyond 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Natural system modifications	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Transportation and service corridors	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	A management plan exists but it is out of date or not comprehensive	Some limited conservation initiatives are in place	low
