The site was identified as important in 2007 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
Red-breasted Goose Branta ruficollis	VU	passage	2004	102 individuals	A1
Greylag Goose Anser anser	LC	passage	1998	7,500 individuals	A4i
Greater White-fronted Goose Anser albifrons	LC	passage	2004	12,000 individuals	A4i
Lesser White-fronted Goose Anser erythropus	VU	passage	2004	36 individuals	A1
Little Gull Hydrocoloeus minutus	LC	breeding	1998	1,500 breeding pairs	A4i
A4iii Species group - waterbirds	n/a	passage	2004	20,000-49,999 individuals	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2007) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2015) is shown below.
