The site was identified as internationally important for bird conservation in 2010 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
Stejneger's Petrel Pterodroma longirostris	VU	breeding (1987)	100,000-499,999 pairs	A1, A4ii
Juan Fernandez Petrel Pterodroma externa	VU	breeding (1987)	1,000,000-2,499,999 pairs	A1, A4ii
Masafuera Rayadito Aphrastura masafuerae	CR	resident (2006–2007)	248 birds	A1, A2, A3
A4iii Species group - seabirds	n/a	breeding (1987)	1,000,000-2,499,999 pairs	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2017) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	good (>90%)	good

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Invasive and other problematic species and genes	happe­ning now	whole of popul­ation/area (>90%)	moderate decline (10–30% over 3 gener­ations)	very 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	A compre­hensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	not assessed

Year	Protected Area	Designation (management category)	% coverage of IBA
1935	Archipielago Juan Fernadez	Parque Nacional (II)	100
2017	Mar de Juan Fernández	Área Marina Costera Protegida (IV)	2
2017	Lobería Selkirk	Parque Marino (Ia)	2
