The site was identified as internationally important for bird conservation in 2008 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
Balearic Shearwater Puffinus mauretanicus	CR	winter (2002–2003)	1,100–3,000 birds	A1, A4ii, B1ii, C2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2008. The most recent assessment (2012) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	happe­ning now	most of popul­ation/area (50–90%)	slow decline (1–10% over 3 gener­ations)	high
Pollution	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low
Energy production and mining	likely in long term (>4 years)	few indivi­duals/small area (<10%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	very low
