The site was identified as internationally important for bird conservation in 2001 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
Fulvous Whistling-duck Dendrocygna bicolor	LC	non-breeding (1984)	23,000 birds	A4i
Ferruginous Duck Aythya nyroca	NT	winter (1987)	5,600 birds	A1, A4i
Garganey Spatula querquedula	LC	winter (1985)	31,270 birds	A4i
Northern Pintail Anas acuta	LC	winter (1985)	27,600 birds	A4i
Great White Egret Ardea alba	LC	non-breeding (1999)	560 birds	A4i
Black-winged Stilt Himantopus himantopus	LC	non-breeding (1978)	1,600 birds	A4i
Black-tailed Godwit Limosa limosa	NT	winter (1985)	6,200 birds	A4i
Ruff Calidris pugnax	LC	winter (1978)	32,000 birds	A4i
Caspian Tern Hydroprogne caspia	LC	winter (1979)	2,000 birds	A4i
White-winged Tern Chlidonias leucopterus	LC	winter (1980)	3,000 birds	A4i
A4iii Species group - waterbirds	n/a	non-breeding (-)	100,000-499,999 birds	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2001. The most recent assessment (2001) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	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
Agricultural expansion and intensification	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
