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	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

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 (2008) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	whole area/population (>90%)	slow but significant deterioration	high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
1969	Unnamed WA29901	Conservation Park	<1
1991	Coomallo	Nature Reserve	48

Habitat1	Habitat detail	% of IBA
Forest	Eucalypt woodlands	major (>10)
Shrubland	Heath	major (>10)

1. IUCN Habitat classification.

Land use	% of IBA
rangeland/pastureland	major (>10)
nature conservation and research	major (>10)
