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	1994	3,700 individuals	A4i, B1i, C3
Whooper Swan Cygnus cygnus	LC	non-breeding	1994	300 individuals	B1i, C2
Greater Scaup Aythya marila	LC	winter	1994	2,075 individuals	B2
Eurasian Golden Plover Pluvialis apricaria	LC	passage	1996	10,000 individuals	B1i, C2
Sandwich Tern Thalasseus sandvicensis	LC	breeding	1994	300 breeding pairs	B2, C6

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.
