The site was identified as internationally important for bird conservation in 2004 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 List	Season (year/s of estimate)	Size	IBA criteria
Whooper Swan Cygnus cygnus	LC	winter (2004)	present	A4i
Bean Goose Anser fabalis	LC	non-breeding (2004)	present	A4i
Falcated Duck Mareca falcata	LC	winter (2004)	present	A4i
Mallard Anas platyrhynchos	LC	non-breeding (2004)	present	A4i
Northern Pintail Anas acuta	LC	unknown (2004)	present	A4i
White-naped Crane Grus vipio	VU	winter (2004)	present	A1
Oriental Stork Ciconia boyciana	EN	winter (2004)	present	A1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2004) is shown below.
