The site was identified as internationally important for bird conservation in 2008 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
Greater White-fronted Goose Anser albifrons	LC	passage (1998)	100,000–300,000 birds	A4i, B1i
Common Goldeneye Bucephala clangula	LC	passage (1997)	3,000–5,000 birds	B1i
Greater Scaup Aythya marila	LC	passage (1997)	3,000–5,000 birds	B1i
Great White Egret Ardea alba	LC	passage (1999)	100–200 birds	A4i, B1i
A4iii Species group - waterbirds	n/a	passage (1998)	100,000-499,999 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2007) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Demoiselle Crane Anthropoides virgo	8 / 10 (pairs)	80	moderate
Black-tailed Godwit Limosa limosa	8 / 10 (pairs)	80	moderate
Larus cachinnans	250 / 300 (pairs)	84	moderate

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Natural system modifications	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	moderate decline (10–30% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Some limited conservation initiatives are in place	very low

Year	Protected Area	Designation (management category)	% coverage of IBA
