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
Australian Shelduck Tadorna tadornoides	LC	resident	-	5,016 individuals	A4i
Banded Stilt Cladorhynchus leucocephalus	LC	non-breeding	1989-2007	60,389 individuals	A4i
Red-necked Avocet Recurvirostra novaehollandiae	LC	non-breeding	-	4,296 individuals	A4i
Red-capped Plover Charadrius ruficapillus	LC	non-breeding	-	1,488 individuals	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 (2019) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	good (> 90%)	poor (40-69%)	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Natural system modifications	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Climate change and severe weather	happening now	whole area/population (>90%)	slow but significant deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible
