The site was identified as important in 2009 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
Mrs Hume's Pheasant Syrmaticus humiae	VU	resident	2004	present	A3
Scaly-sided Merganser Mergus squamatus	EN	winter	2003	present	A1
Red-crested Pochard Netta rufina	LC	non-breeding	2003	min 10,000 individuals	A4i
Gadwall Mareca strepera	LC	non-breeding	2003	present	A4i
Indian Spot-billed Duck Anas poecilorhyncha	LC	resident	2008	present	A4i
Eurasian Coot Fulica atra	LC	non-breeding	2003	min 10,000 individuals	A4i
Yunnan Nuthatch Sitta yunnanensis	LC	resident	2000	present	A2, A3
Giant Nuthatch Sitta magna	EN	resident	2003	present	A1, A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2009) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2009. The most recent assessment (2008) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	-	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Biological resource use	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	likely in long term (beyond 4 years)	small area/few individuals (<10%)	slow but significant deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Most of site (50-90%) covered (including the most critical parts for important bird species)	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation	% overlap with IBA
