The site was identified as important in 2000 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Mew Gull Larus canus	LC	breeding	1996	1,000 breeding pairs	B2
Lesser Black-backed Gull Larus fuscus	LC	breeding	1996	1,030 breeding pairs	B1i, B3, C3
Caspian Tern Hydroprogne caspia	LC	breeding	1996	11 breeding pairs	B2, C6
Arctic Tern Sterna paradisaea	LC	breeding	1996	1,200 breeding pairs	C2
Black Guillemot Cepphus grylle	LC	breeding	1996	560 breeding pairs	B1ii, B2
Razorbill Alca torda	LC	breeding	1996	710 breeding pairs	B1ii, B3, C3

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2000).
