The site was identified as important in 2019 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	2015-2019	6-100 individuals	A1, B3b
Peruvian Diving-petrel Pelecanoides garnotii	NT	non-breeding	2015-2019	9-250 individuals	A1, B3b
Peruvian Pelican Pelecanus thagus	NT	resident	2015-2019	12-25 individuals	B3b
Peruvian Booby Sula variegata	LC	breeding	2003	18,000 individuals	A4, B3b
Red-legged Cormorant Poikilocarbo gaimardi	NT	resident	2015-2019	4-6 individuals	B3b
Guanay Cormorant Leucocarbo bougainvilliorum	NT	breeding	2015-2019	4-45 individuals	B1a, B3b
Neotropical Cormorant Nannopterum brasilianum	LC	breeding	2003	50 individuals	B3b
Kelp Gull Larus dominicanus	LC	breeding	2003	2,000 individuals	B3b
Inca Tern Larosterna inca	NT	breeding	2015-2019	3-12 individuals	B3b

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2019) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2019. The most recent assessment (2019) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high
Human intrusions and disturbance	likely in short term (within 4 years)	whole area/population (>90%)	very rapid to severe deterioration	very high
Climate change and severe weather	likely in long term (beyond 4 years)	whole area/population (>90%)	slow but significant deterioration	medium
Biological resource use	happening now	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
Little/none of site covered (<10%)	No management planning has taken place	Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity	low

Habitat1	Habitat detail	% of IBA
Marine Coastal/Supratidal		major (>10)
Shrubland	Arid lowland scrub	major (>10)

1. IUCN Habitat classification.

Land use	% of IBA
nature conservation and research	major (>10)
