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
Australian Shelduck Tadorna tadornoides	LC	resident (2000–2005)	2,738–8,581 birds	A4i
Chestnut Teal Anas castanea	LC	resident (2000–2007)	3,037–21,304 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 (2016) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Climate change and severe weather	happe­ning now	most of popul­ation/area (50–90%)	rapid decline (>30% over 3 gener­ations)	very high
Invasive and other problematic species and genes	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Human intrusions and disturbance	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low
