The site was identified as internationally important for bird conservation in 2012 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
Bar-headed Goose Anser indicus	LC	winter (2008–2012)	max 1,400 birds	A4i
Spoon-billed Sandpiper Calidris pygmaea	CR	winter (2008–2012)	22–35 birds	A1, A4i
Spotted Greenshank Tringa guttifer	EN	winter (2008–2012)	3–5 birds	A1

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2012. The most recent assessment (2019) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	most of popul­ation/area (50–90%)	rapid decline (>30% over 3 gener­ations)	very high
Climate change and severe weather	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Human intrusions and disturbance	happe­ning now	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
