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') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
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

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2000) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2000. The most recent assessment (2010) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Mew Gull Larus canus	1,000	600	individuals	60	unfavourable
Lesser Black-backed Gull Larus fuscus	1,000	500	individuals	50	unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Pollution	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	No management plan exists but the management planning process has begun	Some limited conservation initiatives are in place	low
