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
Humboldt Penguin Spheniscus humboldti	VU	breeding	-	40 breeding pairs	A1

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 (2015) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	good (> 90%)	favourable
Marine Coastal/Supratidal	-	good (> 90%)	favourable
Wetlands (inland)	-	good (> 90%)	favourable
Rocky areas (eg. inland cliffs, mountain peaks)	-	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Agricultural expansion and intensification	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Transportation and service corridors	happening now	small area/few individuals (<10%)	moderate to rapid deterioration	low
Invasive and other problematic species and genes	likely in long term (beyond 4 years)	small area/few individuals (<10%)	moderate to rapid deterioration	low

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90%) covered by appropriate conservation designation	A management plan exists but it is out of date or not comprehensive	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	medium

Year	Protected Area	Designation	% overlap with IBA
1988	Hornopiren	Parque Nacional	69

Habitat1	Habitat detail	% of IBA
Forest		51
Rocky areas (eg. inland cliffs, mountain peaks)		46
Wetlands (inland)		2
Marine Coastal/Supratidal		1

1. IUCN Habitat classification.
