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
Greylag Goose Anser anser	LC	breeding	1992	130 breeding pairs	B1i
Common Teal Anas crecca	LC	passage	1992	25,000 individuals	A4i, B1i
Glossy Ibis Plegadis falcinellus	LC	breeding	1993	120-1,500 breeding pairs	A4i, B1i, B2
Black-crowned Night-heron Nycticorax nycticorax	LC	breeding	1993	1,000-2,500 breeding pairs	A4i, B1i, B2
Purple Heron Ardea purpurea	LC	breeding	1993	100-150 breeding pairs	B2
Great White Egret Ardea alba	LC	breeding	1992	110-330 breeding pairs	A4i, B1i
Great Cormorant Phalacrocorax carbo	LC	breeding	1993	2,000-2,500 breeding pairs	A4i, B1i
A4iii Species group - waterbirds	n/a	passage	1992	20,000-49,999 individuals	A4iii

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