The site was identified as important in 2004 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
Garganey Spatula querquedula	LC	non-breeding	2004	present	A4i
Asian Openbill Anastomus oscitans	LC	resident	2004	present	A4i
Spot-billed Pelican Pelecanus philippensis	NT	resident	2004	present	A1
A4iii Species group - waterbirds	n/a	unknown	2004	min 20,000 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2003) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	very rapid to severe deterioration	high
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	happening now	small area/few individuals (<10%)	very rapid to severe deterioration	low
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Pollution	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Climate change and severe weather	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
