The site was identified as internationally important for bird conservation in 2004 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
Red-breasted Goose Branta ruficollis	VU	winter (1993–2002)	75–80 birds	A1, B2
Common Pochard Aythya ferina	VU	winter (1996)	14,036 birds	A4i, B1i
Little Gull Hydrocoloeus minutus	LC	passage (1991)	1,740 birds	A4i, B1i
Mediterranean Gull Larus melanocephalus	LC	passage (1995)	10,000 birds	A4i, B1i
Yellow-legged Gull Larus michahellis	LC	winter (1994–1996)	1,250–8,775 birds	B1i
A4iii Species group - waterbirds	n/a	winter (1996)	22,681 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2016) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	good (>90%)	moderate (70–90%)	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Most of area (50–90%) covered (including the most critical parts for important bird species)	A management plan exists, but it is out of date or not compre­hensive	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium

Habitat	% of IBA	Habitat detail
Marine Coastal/Supratidal	100

Land use	% of IBA
water management	100
