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
Peruvian Pelican Pelecanus thagus	NT	non-breeding	-	400 individuals	A1
South American Tern Sterna hirundinacea	LC	resident	-	4,000 individuals	A4i

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

IBA conservation assessment
Year of assessment	State	Pressure	Response
2021	very unfavourable	medium	negligible
Whole site assessed?	State assessed by	Accuracy of information
yes	habitat	good

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result

Marine Intertidal	moderate (70-90%)	good (> 90%)	near favourable
Marine Neritic	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)

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	Very little or no conservation action taking place	negligible
