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	-	min 6	A1
Black Stilt Himantopus novaezelandiae	CR	breeding	2009-2013	max 2 individuals	A1
Wrybill Anarhynchus frontalis	VU	non-breeding	2009-2013	349-701 individuals	A1, A4i
Black-billed Gull Larus bulleri	NT	breeding	-	311-530 breeding pairs	A1, A4i
Black-fronted Tern Chlidonias albostriatus	EN	non-breeding	2006-2015	28-54 individuals	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
Natural system modifications	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Climate change and severe weather	likely in short term (within 4 years)	some of area/population (10-49%)	moderate to rapid deterioration	medium
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
