The site was identified as important in 2014 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
Long-tailed Duck Clangula hyemalis	VU	winter	2011	500 individuals	A1
Velvet Scoter Melanitta fusca	VU	winter	2008	265 individuals	A1, B2
Horned Grebe Podiceps auritus	VU	winter	2004-2013	100-150 individuals	B1i, B2
Eurasian Curlew Numenius arquata	NT	breeding	2013	10 breeding pairs	A1
Lesser Black-backed Gull Larus fuscus	LC	breeding	2013	2,237 breeding pairs	B1i, B3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2014) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2016) is shown below.
