The site was identified as internationally important for bird conservation in 2007 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
Red-billed Chough Pyrrhocorax pyrrhocorax	LC	breeding (2000–2004)	5 pairs	B2

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2007. The most recent assessment (2007) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	likely in short term (<4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium
Human intrusions and disturbance	likely in short term (<4 years)	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Some limited conservation initiatives are in place	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
1951	Snowdonia	National Park (V)	100
1954	Craig Yr Aderyn (Bird'S Rock)	Site of Special Scientific Interest (UK) (IV)	100

Habitat	% of IBA	Habitat detail
Rocky areas (eg. inland cliffs, mountain peaks)	major (>10)	Inland cliffs; Scree & boulders
