The site was identified as internationally important for bird conservation in 2009 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Pied Oystercatcher Haematopus longirostris	LC	resident (2005)	196 individuals	A4i
Grey-tailed Tattler Tringa brevipes	LC	non-breeding (2005)	3,184 individuals	A4i
Dusky Gerygone Gerygone tenebrosa	LC	resident (2005)	common	A2

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 key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	likely in long term (beyond 4 years)	some of popul­ation/area (10–49%)	slow deteri­oration (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the key species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed

Year	Protected Area	Designation (management category)	% coverage of IBA
