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'):

Species	Current IUCN Red List Category	Season	Year(s)	Population estimate at site	IBA criteria met
Leach's Storm-petrel Hydrobates leucorhous	VU	breeding	1999	20 breeding pairs	C6

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2007).

State (condition of the trigger species' populations)
Scientific name	Common name	Reference population	Actual population	Units	% of population remaining	Result
Hydrobates leucorhous		22	20	breeding pairs	91	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat level 1	Threat level 2	Timing	Scope	Severity	Result
Climate change and severe weather	habitat shifting and alteration	happening now	whole area/population (>90%)	very rapid to severe deterioration	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected-area designation	Management planning	Other conservation action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Not assessed	medium
