The site was identified as internationally important for bird conservation in 2000 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 List	Season (year/s of estimate)	Size	IBA criteria
Little Gull Hydrocoloeus minutus	LC	breeding (1996)	254 pairs	B1i, B2, C3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Little Gull Hydrocoloeus minutus	0 / 250 (pairs)	0	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happe­ning now	whole of popul­ation/area (>90%)	slow decline (1–10% over 3 gener­ations)	high
Invasive and other problematic species and genes	happe­ning now	some of popul­ation/area (10–49%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Unknown	low

Habitat	% of IBA	Habitat detail
Wetlands (inland)	100	Standing freshwater
