The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Coscoroba Swan Coscoroba coscoroba	LC	breeding (2005–2008)	193 birds	A4i
Coscoroba Swan Coscoroba coscoroba	LC	resident (2016–2020)	6–350 birds	A4
Chilean Flamingo Phoenicopterus chilensis	NT	non-breeding (2016–2020)	1–59 birds	B1a
Peruvian Pelican Pelecanus thagus	NT	resident (2016–2020)	3–201 birds	B1a
Red-legged Cormorant Poikilocarbo gaimardi	NT	resident (2016–2020)	3–231 birds	B1a
Guanay Cormorant Leucocarbo bougainvilliorum	NT	resident (2016–2020)	3–7,500 birds	B1a
Franklin's Gull Larus pipixcan	LC	non-breeding (2005–2008)	10,000 birds	A4i
Elegant Tern Thalasseus elegans	NT	non-breeding (2016–2020)	2–1,018 birds	A4, B1a

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 poor
Marine Coastal/Supratidal	-	poor (40–69%)	very poor

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Residential and commercial development	happe­ning now	some of popul­ation/area (10–49%)	moderate decline (10–30% over 3 gener­ations)	high
Agricultural expansion and intensification	happe­ning now	some of popul­ation/area (10–49%)	slow decline (1–10% over 3 gener­ations)	medium

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>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 (management category)	% coverage of IBA
-	Península de Hualpén	Nature Sanctuary or Partial Reserve (-)	100
1976	Península de Hualpén	Santuario de la Naturaleza (IV)	81

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