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'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Bean Goose Anser fabalis	LC	passage	1996	5,000-25,000 individuals	A4i, B1i, C3
Common Crane Grus grus	LC	passage	1996	200-2,500 individuals	A4i, B1i, C2
Western Marsh-harrier Circus aeruginosus	LC	breeding	1996	15-18 breeding pairs	C6
Common Grasshopper-warbler Locustella naevia	LC	breeding	1996	25-50 breeding pairs	B3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2000).
