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
Blue-billed Duck Oxyura australis	LC	non-breeding (1997–2007)	119 birds	A1
Red-necked Avocet Recurvirostra novaehollandiae	LC	non-breeding (1994–2006)	251–5,468 birds	A4i
Black-winged Stilt Himantopus himantopus	LC	breeding (1995–2005)	1,680–5,400 birds	A4i
Red-capped Plover Charadrius ruficapillus	LC	resident (1995–2005)	212–2,500 birds	A4i
Sharp-tailed Sandpiper Calidris acuminata	VU	non-breeding (1993–2006)	773–5,970 birds	A4i
Red-necked Stint Calidris ruficollis	NT	non-breeding (1996–2006)	2,500–11,700 birds	A4i

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	happe­ning now	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
