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 (1994)	885 birds	A4i, B1i, C2
Tundra Swan Cygnus columbianus	LC	winter (1994)	377 birds	A4i, B1i, B2, C2
Pink-footed Goose Anser brachyrhynchus	LC	non-breeding (1994)	2,600 birds	A4i, B1i, C3
Red-breasted Merganser Mergus serrator	LC	non-breeding (1994)	1,560 birds	B1i, C3
Eurasian Bittern Botaurus stellaris	LC	breeding (1995)	92 pairs	B2, C2, C6
Pied Avocet Recurvirostra avosetta	LC	breeding (1994)	280 pairs	B1i, B3, C2
Eurasian Golden Plover Pluvialis apricaria	LC	passage (1994)	18,000 birds	A4i, B1i, C2
Black-tailed Godwit Limosa limosa	NT	breeding (1994)	110 pairs	B2
Black Tern Chlidonias niger	LC	breeding (1994)	28–40 pairs	C2, C6
A4iii Species group - waterbirds	n/a	unknown (1994)	20,000-49,999 birds	A4iii, C4

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.
