The site was identified as important in 2010 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
Greater White-fronted Goose Anser albifrons	LC	passage	2008	15,300 individuals	C3
Common Little Bittern Ixobrychus minutus	LC	breeding	2007	5-15 breeding pairs	C6

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2011) is shown below.
