The site was identified as internationally important for bird conservation in 2005 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
Common Goldeneye Bucephala clangula	LC	passage (2005)	300 birds	A4i
Common Shelduck Tadorna tadorna	LC	passage (2005)	545–835 birds	A4i
Ruddy Shelduck Tadorna ferruginea	LC	passage (2005)	1,500 birds	A4i
Northern Shoveler Spatula clypeata	LC	passage (2002–2005)	6,000–50,000 birds	A4i
Eurasian Wigeon Mareca penelope	LC	passage (2002–2005)	2,500–20,000 birds	A4i
Mallard Anas platyrhynchos	LC	passage (2002–2005)	12,000–22,000 birds	A4i
Northern Pintail Anas acuta	LC	passage (2002–2005)	3,500–15,000 birds	A4i
Black-tailed Godwit Limosa limosa	NT	passage (2000–2008)	257–1,430 birds	A1, A4i
Ruff Calidris pugnax	LC	passage (2000)	39,500 birds	A4i
Red-necked Phalarope Phalaropus lobatus	LC	passage (2000)	43,600 birds	A4i
A4iii Species group - waterbirds	n/a	passage (2000–2005)	35,000–104,000 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2005. The most recent assessment (2005) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Grassland	moderate (70–90%)	moderate (70–90%)	poor
Desert	good (>90%)	moderate (70–90%)	moderate
Wetlands (inland)	moderate (70–90%)	good (>90%)	moderate
Shrubland	good (>90%)	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Climate change and severe weather	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Residential and commercial development	happe­ning now	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed
