The site was identified as important in 2020 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	2003	600 individuals	A1, A4ii
Humboldt Penguin Spheniscus humboldti	VU	breeding	2016-2020	8-250 individuals	A1
Brown Pelican Pelecanus occidentalis	LC	breeding	2001-2002	400-3,000 breeding pairs	A1
Peruvian Pelican Pelecanus thagus	NT	resident	2016-2020	6-800 individuals	B1a
Guanay Cormorant Leucocarbo bougainvilliorum	NT	resident	2016-2020	30-1,200 individuals	B1a

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2020) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2020. The most recent assessment (2020) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Marine Coastal/Supratidal	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Invasive and other problematic species and genes	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Climate change and severe weather	likely in long term (beyond 4 years)	majority/most of area/population (50-90%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Pollution	happening now	small area/few individuals (<10%)	slow but significant 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 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	high

Year	Protected Area	Designation	% overlap with IBA
1989	Isla Cachagua	Monumento Natural	100

Habitat1	Habitat detail	% of IBA
Marine Coastal/Supratidal		major (>10)
