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
Australasian Bittern Botaurus poiciloptilus	VU	resident	1998-2008	uncommon	A1
Banded Stilt Cladorhynchus leucocephalus	LC	non-breeding	2000-2008	60,000 individuals	A4i
Double-banded Plover Charadrius bicinctus	NT	non-breeding	2004-2005	600 individuals	A4i
Sharp-tailed Sandpiper Calidris acuminata	VU	non-breeding	1999-2008	6,440 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 (2013) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	likely in long term (beyond 4 years)	whole area/population (>90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation	% overlap with IBA
1989	Unnamed (No.HA245)	Heritage Agreement	<1
1991	Little Dip	Conservation Park	1
1991	Unnamed (No.HA453)	Heritage Agreement	<1
