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
Black-faced Spoonbill Platalea minor	EN	winter (2003)	present	A1, 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 (2010) is shown below.

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Human intrusions and disturbance	likely in long term (>4 years)	few indivi­duals/small area (<10%)	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
Little/none of area covered (<10%)	Unknown	Unknown	very low

Year	Protected Area	Designation (management category)	% coverage of IBA
1953	Fukiagehama	都道府県立自然公園 (V)	100
2013	Common fishery right area(Kagoshima)	共同漁業権区域 (VI)	52

Habitat	% of IBA	Habitat detail
