The site was identified as important in 2001 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
Marbled Duck Marmaronetta angustirostris	NT	winter	1999	1,420 individuals	A1, A4i
Black-winged Stilt Himantopus himantopus	LC	winter	1999	1,340 individuals	A4i
Audouin's Gull Larus audouinii	VU	winter	1999	670 individuals	A1, A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2001) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2001) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Marbled Duck Marmaronetta angustirostris	1,420	1,420	individuals	100	favourable
Himantopus himantopus	1,340	1,340	individuals	100	favourable
Audouin's Gull Larus audouinii	670	670	individuals	100	favourable

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	good (> 90%)	good (> 90%)	favourable
Artificial/Aquatic & Marine	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Pollution	likely in long term (beyond 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	likely in short term (within 4 years)	small area/few individuals (<10%)	moderate to rapid deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	No management planning has taken place	Very little or no conservation action taking place	low
