The site was identified as important in 2007 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
Greylag Goose Anser anser	LC	winter	2007	323-12,868 individuals	A4i
Lesser White-fronted Goose Anser erythropus	VU	winter	2007	7-18 individuals	A1
Ruddy Shelduck Tadorna ferruginea	LC	winter	2007	528-2,986 individuals	A4i
Demoiselle Crane Anthropoides virgo	LC	passage	2007	28-1,004 individuals	A4i
Common Crane Grus grus	LC	passage	2007	18-1,103 individuals	A4i
Great Cormorant Phalacrocorax carbo	LC	winter	2007	108-4,640 individuals	A4i
A4iii Species group - waterbirds	n/a	winter	2007	3,091-20,825 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Natural system modifications	happening now	whole area/population (>90%)	moderate to rapid deterioration	very high
Pollution	happening now	whole area/population (>90%)	slow but significant deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Climate change and severe weather	likely in short term (within 4 years)	some of area/population (10-49%)	slow but significant deterioration	medium
Residential and commercial development	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Agricultural expansion and intensification	past (and unlikely to return) and no longer limiting	whole area/population (>90%)	moderate to rapid deterioration	low
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
