The site was identified as internationally important for bird conservation in 2012 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
Black-necked Grebe Podiceps nigricollis	LC	winter (-)	600–2,500 birds	A4i
Greater Flamingo Phoenicopterus roseus	LC	winter (1999)	750–7,000 birds	A4i
Eurasian Spoonbill Platalea leucorodia	LC	winter (-)	200–600 birds	A4i
Pied Avocet Recurvirostra avosetta	LC	breeding (-)	1,000 birds	A4i
Pied Avocet Recurvirostra avosetta	LC	winter (-)	1,000–2,000 birds	A4i
Curlew Sandpiper Calidris ferruginea	VU	winter (-)	2,000–5,500 birds	A4i
Little Stint Calidris minuta	LC	winter (-)	2,500–5,500 birds	A4i
Slender-billed Gull Larus genei	LC	breeding (-)	1,400 birds	A4i
Slender-billed Gull Larus genei	LC	winter (-)	1,400–3,000 birds	A4i
Sandwich Tern Thalasseus sandvicensis	LC	winter (-)	400–3,500 birds	A4i
A4iii Species group - waterbirds	n/a	winter (-)	min 20,000 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2009) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Invasive and other problematic species and genes	likely in short term (<4 years)	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	medium
Climate change and severe weather	likely in long term (>4 years)	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% 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90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium
