The site was identified as internationally important for bird conservation in 2000 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
Whooper Swan Cygnus cygnus	LC	winter (1995)	885 birds	A4i, B1i, C2
Common Goldeneye Bucephala clangula	LC	non-breeding (1988)	5,000–6,000 birds	A4i, B1i, C3
Common Pochard Aythya ferina	VU	non-breeding (1988)	2,000–4,000 birds	B1i, C3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Actual vs Reference (units)	% remaining	Result
Tundra Swan Cygnus columbianus	69 / 69 (birds)	100	good
Common Shelduck Tadorna tadorna	450 / 450 (birds)	100	good
