The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Red-breasted Goose Branta ruficollis	VU	winter	1993-2002	75-80 individuals	A1, B2
Common Pochard Aythya ferina	VU	winter	1996	14,036 individuals	A4i, B1i
Little Gull Hydrocoloeus minutus	LC	passage	1991	1,740 individuals	A4i, B1i
Mediterranean Gull Larus melanocephalus	LC	passage	1995	10,000 individuals	A4i, B1i
Yellow-legged Gull Larus michahellis	LC	winter	1994-1996	1,250-8,775 individuals	B1i
A4iii Species group - waterbirds	n/a	winter	1996	22,681 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

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%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium
