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
Straw-necked Ibis Threskiornis spinicollis	LC	breeding	1995	12,300 individuals	A4i
Australian Pelican Pelecanus conspicillatus	LC	breeding	1993	5,000 breeding pairs	A4i

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
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
