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 (1989–2008)	510 birds	A1, A4i
Chestnut Teal Anas castanea	LC	non-breeding (1989–2008)	1,962 birds	A4i
Australasian Bittern Botaurus poiciloptilus	VU	non-breeding (1989–2008)	14 birds	A1
Sharp-tailed Sandpiper Calidris acuminata	VU	non-breeding (1989–2008)	5,839 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
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Pollution	happe­ning now	most of popul­ation/area (50–90%)	no or slight decline (<1% over 3 gener­ations)	low
