The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Stejneger's Petrel Pterodroma longirostris	VU	breeding	1987	100,000-499,999 breeding pairs	A1, A4ii
Juan Fernandez Petrel Pterodroma externa	VU	breeding	1987	1,000,000-2,499,999 breeding pairs	A1, A4ii
Masafuera Rayadito Aphrastura masafuerae	CR	resident	2006-2007	248 individuals	A1, A2, A3
A4iii Species group - seabirds	n/a	breeding	1987	1,000,000-2,499,999 breeding pairs	A4iii

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2010) may differ.

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%)	favourable

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 area/population (>90%)	moderate to rapid deterioration	very high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>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	% overlap with IBA
1935	Archipielago Juan Fernadez	Parque Nacional	100
2017	Mar de Juan Fernández	Área Marina Costera Protegida	2
2017	Lobería Selkirk	Parque Marino	2
