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
Greater Scaup Aythya marila	LC	winter (2003)	present	A4i
Little Ringed Plover Charadrius dubius	LC	breeding (2003)	present	A4i
Grey-headed Lapwing Vanellus cinereus	LC	breeding (2003)	present	A4i
Whimbrel Numenius phaeopus	LC	passage (2003)	present	A4i
Ruddy Turnstone Arenaria interpres	NT	passage (2003)	present	A4i
Red-necked Stint Calidris ruficollis	NT	passage (2003)	present	A4i
Dunlin Calidris alpina	NT	winter (2003)	present	A4i
Grey-tailed Tattler Tringa brevipes	LC	passage (2003)	present	A4i

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 2004. The most recent assessment (2015) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Energy production and mining	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%)	Unknown	Very little or no conservation action taking place	very low

Year	Protected Area	Designation (management category)	% coverage of IBA
-	Shiokawa Prefectural National Park	Other (-)	-

Habitat	% of IBA	Habitat detail
Marine Intertidal	major (>10)
Marine Neritic	major (>10)
