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
Northern Gannet Morus bassanus	LC	breeding	1998	8,017 breeding pairs	A4ii, B1ii, B2, C3
Great Skua Catharacta skua	LC	breeding	2001	432 breeding pairs	A4ii, B1ii, B3, C3
Common Murre Uria aalge	LC	breeding	2000	45,782 individuals	B1ii, C3
A4iii Species group - seabirds	n/a	breeding	1998-2001	47,409 breeding pairs	A4iii, C4

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 (2007) is shown below.

State (condition of the trigger species' populations)
Species	Reference	Actual	Units	% remaining	Result
Northern Gannet Morus bassanus	7,300	8,017	breeding pairs	100	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
