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
Wood Sandpiper Tringa glareola	LC	breeding (1994)	13–15 pairs	C6

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
Greylag Goose Anser anser	8,000 / 8,000 (birds)	100	good
Bean Goose Anser fabalis	600 / 680 (birds)	89	moderate
