The site was identified as internationally important for bird conservation in 2011 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
European Storm-petrel Hydrobates pelagicus	LC	breeding (2008)	800–1,450 pairs	B1ii, B3, C2, C6
Scopoli's Shearwater Calonectris diomedea	LC	breeding (2008)	150–275 pairs	C6
Balearic Shearwater Puffinus mauretanicus	CR	breeding (2001–2005)	265–350 pairs	A1, A4ii, B1ii, B2, C1, C2, C6
Audouin's Gull Larus audouinii	VU	breeding (2006)	273 pairs	A1, A4i, B1i, B2, C1, C2, C6

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2011. 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	likely in short term (<4 years)	whole of popul­ation/area (>90%)	rapid decline (>30% over 3 gener­ations)	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Not assessed	Not assessed	Not assessed	not assessed
