The site was identified as internationally important for bird conservation in 2002 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 List	Season (year/s of estimate)	Size	IBA criteria
Plain Swift Apus unicolor	LC	breeding (2002)	common	A2, B3
Band-rumped Storm-petrel Hydrobates castro	LC	breeding (2002)	rare	B2, C6
Roseate Tern Sterna dougallii	LC	breeding (2002)	rare	C6
Common Tern Sterna hirundo	LC	breeding (2002)	frequent	C6
Berthelot's Pipit Anthus berthelotii	LC	resident (2002)	abundant	A2, B3
Island Canary Serinus canaria	LC	resident (2002)	abundant	A2, B3

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2002. The most recent assessment (2014) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	rapid decline (>30% over 3 gener­ations)	high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	Not assessed	Not assessed	low

Habitat	% of IBA	Habitat detail
