The site was identified as important in 2016 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
Barnacle Goose Branta leucopsis	LC	breeding	2011-2015	444-536 breeding pairs	C2
Gadwall Mareca strepera	LC	non-breeding	2011-2015	1,782-2,449 individuals	B1i, C3
Eurasian Wigeon Mareca penelope	LC	non-breeding	2011-2015	44,338-56,500 individuals	A4i, B1i, C3
Eurasian Wigeon Mareca penelope	LC	winter	2011-2015	35,907 individuals	B3
A4iii Species group - waterbirds	n/a	non-breeding	2011-2015	53,287-61,823 individuals	A4iii, C4

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2016) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2016. The most recent assessment (2017) is shown below.
