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
Pleske's Grasshopper-warbler Helopsaltes pleskei	VU	breeding (2003)	present	A1

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
Little/none of area covered (<10%)	A management plan exists, but it is out of date or not compre­hensive	Unknown	low

Year	Protected Area	Designation (management category)	% coverage of IBA
2012	Kirishima kinkowan	国立公園 (II)	100
2013	Common fishery right area(Kagoshima)	共同漁業権区域 (VI)	8
