The site was identified as internationally important for bird conservation in 2004 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
Leach's Storm-petrel Hydrobates leucorhous	VU	breeding (2003)	present	A4ii
Slaty-backed Gull Larus schistisagus	LC	breeding (2003)	present	A4i
A4iii Species group - seabirds	n/a	breeding (2003)	min 10,000 pairs	A4iii

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
No known threats	happe­ning now	whole of popul­ation/area (>90%)	no or slight decline (<1% over 3 gener­ations)	low

Response (conservation actions taken for the trigger species and/or their habitats)
Designation	Planning	Action	Result
Whole area (>90%) covered by appropriate conservation designation	A management plan exists, but it is out of date or not compre­hensive	Substantive conservation measures are being implemented, but these are not compre­hensive and are limited by resources and capacity	medium

Year	Protected Area	Designation (management category)	% coverage of IBA
1955	Akkeshi	都道府県立自然公園 (V)	100
1972	Daikokujima	国指定鳥獣保護区 (IV)	100
