The site was identified as important in 2021 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	2013-2020	143-625 individuals	B3a, C2
Bean Goose Anser fabalis	LC	non-breeding	2013	100-3,450 individuals	B2a, B3a, C3
