The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Whooper Swan Cygnus cygnus	LC	non-breeding	1983	1,000 individuals	A4i, B1i, C2
Tundra Swan Cygnus columbianus	LC	non-breeding	1989	320 individuals	A4i, B1i, B2, C2
Pink-footed Goose Anser brachyrhynchus	LC	non-breeding	1983	3,750 individuals	A4i, B1i, C3
Common Shelduck Tadorna tadorna	LC	non-breeding	-	4,445 individuals	A4i, B1i, C3
Common Teal Anas crecca	LC	non-breeding	1989	4,000 individuals	B1i, C3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

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.
