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
Mute Swan Cygnus olor	LC	non-breeding	1991	3,818 individuals	A4i, B1i, C3
Barnacle Goose Branta leucopsis	LC	breeding	1998	25 breeding pairs	C2
Greylag Goose Anser anser	LC	non-breeding	1991	2,616 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.
