The site was identified as important in 2014 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
Australasian Bittern Botaurus poiciloptilus	VU	resident	-	present	A1
Northern Red-breasted Plover Charadrius aquilonius	LC	resident	2012-2015	6-7 breeding pairs	A1
Black-billed Gull Larus bulleri	NT	breeding	2010-2015	13-26 breeding pairs	A1

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2014) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2014) is shown below.

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
Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Residential and commercial development	happening now	some of area/population (10-49%)	no or imperceptible deterioration	low

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