The site was identified as internationally important for bird conservation 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 List	Season (year/s of estimate)	Size	IBA criteria
Macaroni Penguin Eudyptes chrysolophus	VU	breeding (2006)	15,600 pairs	A1
Southern Rockhopper Penguin Eudyptes chrysocome	VU	breeding (2006)	132,721 pairs	A1, A4ii
Grey-headed Albatross Thalassarche chrysostoma	EN	breeding (2006)	17,000 pairs	A1, A4ii
Black-browed Albatross Thalassarche melanophris	LC	breeding (2003)	55,000 pairs	A1, A4ii
Blue Petrel Halobaena caerulea	LC	breeding (2006)	1,350,000 pairs	A4ii
A4iii Species group - seabirds	n/a	breeding (2006)	1,000,000-2,499,999 pairs	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2010. The most recent assessment (2015) is shown below.

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

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Biological resource use	happe­ning now	few indivi­duals/small area (<10%)	slow decline (1–10% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Little/none of area covered (<10%)	No management planning has taken place	Some limited conservation initiatives are in place	very low

Year	Protected Area	Designation (management category)	% coverage of IBA
2019	Islas Diego Ramírez y Paso Drake	Parque Marino (Ia)	100
