The site was identified as important in 2016 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Gadwall Mareca strepera	LC	non-breeding	2011-2015	2,531-3,701 individuals	B1i, C3
Common Ringed Plover Charadrius hiaticula	LC	breeding	2011-2015	17 breeding pairs	B3
