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
Malleefowl Leipoa ocellata	VU	resident	2006-2008	9-11 nests	A1
Fairy Tern Sternula nereis	VU	breeding	1998-2008	uncommon	A1
Rock Parrot Neophema petrophila	LC	resident	1998-2008	frequent	A3
Purple-gaped Honeyeater Lichenostomus cratitius	LC	resident	1998-2008	abundant	A3
Western Whipbird Psophodes nigrogularis	LC	resident	1998-2008	frequent	A1, 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
Climate change and severe weather	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Natural system modifications	happening now	whole area/population (>90%)	no or imperceptible deterioration	low
Human intrusions and disturbance	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low

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
