The site was identified as important in 2010 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
Corncrake Crex crex	LC	breeding	2004-2009	100-300 males	C1, C6
Black-tailed Godwit Limosa limosa	NT	breeding	2009	90 breeding pairs	C1
