The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Bean Goose Anser fabalis	LC	winter (2004–2009)	25,500 birds	C3
Bean Goose Anser fabalis	LC	passage (2004–2009)	18,847 birds	C3
Greater White-fronted Goose Anser albifrons	LC	passage (2004–2009)	15,575 birds	C3
Great Crested Grebe Podiceps cristatus	LC	passage (2004–2009)	10,300 birds	C3
Common Crane Grus grus	LC	passage (2001–2006)	5,000 birds	C2
Eurasian Curlew Numenius arquata	NT	breeding (2004–2009)	2–10 pairs	C1
Aquatic Warbler Acrocephalus paludicola	VU	breeding (2005)	14 males	C1
A4iii Species group - waterbirds	n/a	passage (2004–2009)	70,000 birds	C4
A4iii Species group - waterbirds	n/a	winter (2004–2009)	44,000 birds	C4

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high
Residential and commercial development	happe­ning now	most of popul­ation/area (50–90%)	rapid decline (>30% over 3 gener­ations)	very high
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Transportation and service corridors	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
