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
Coscoroba Swan Coscoroba coscoroba	LC	breeding	2005-2008	193 individuals	A4i
Coscoroba Swan Coscoroba coscoroba	LC	resident	2016-2020	6-350 individuals	A4
Chilean Flamingo Phoenicopterus chilensis	NT	non-breeding	2016-2020	1-59 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 (2014) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Forest	-	very poor (< 40%)	very unfavourable
Marine Coastal/Supratidal	-	poor (40-69%)	very unfavourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happening now	some of area/population (10-49%)	moderate to rapid deterioration	high
Agricultural expansion and intensification	happening now	some of area/population (10-49%)	slow but significant deterioration	medium

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	No management plan exists but the management planning process has begun	Very little or no conservation action taking place	low

Year	Protected Area	Designation	% overlap with IBA
-	Península de Hualpén	Nature Sanctuary or Partial Reserve	100
1976	Península de Hualpén	Santuario de la Naturaleza	81

Habitat1	Habitat detail	% of IBA
Forest		major (>10)
Marine Coastal/Supratidal		minor (<10)
Marine Intertidal		minor (<10)
Marine Neritic		minor (<10)
