The site was identified as internationally important for bird conservation in 2014 because it was regularly supporting significant populations of the species listed below, meeting IBA criteria.

Populations meeting IBA criteria ('key species') at the site:

Species	Red List	Season (year/s of estimate)	Size	IBA criteria
Atlantic Puffin Fratercula arctica	VU	breeding (2009)	40,000 breeding pairs	A4ii, B1ii, B2
A4iii Species group - seabirds	n/a	breeding (2009)	40,000 breeding pairs	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2014. The most recent assessment (2017) is shown below.

Pressure (threats to the key species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happen­ing now	whole popul­ation/area (>90%)	slow deteri­oration (1–10% over 3 gener­ations)	high
Human intrusions and disturbance	happen­ing now	most of popul­ation/area (50–90%)	slow deteri­oration (1–10% over 3 gener­ations)	high
