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
European Storm-petrel Hydrobates pelagicus	LC	breeding	2001	994 breeding pairs	B2, C6

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
European Storm-petrel Hydrobates pelagicus	3,610	994	breeding pairs	28	not assessed

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
