The site was identified as important 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 List1	Season	Year(s)	Size	IBA criteria
Mandarin Duck Aix galericulata	LC	winter	2003	present	A4i

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (2004) may differ.

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.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Wetlands (inland)	good (> 90%)	moderate (70-90%)	near favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Geological events	happening now	majority/most of area/population (50-90%)	slow but significant deterioration	high
Human intrusions and disturbance	happening now	majority/most of area/population (50-90%)	moderate to rapid deterioration	high

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Little/none of site covered (<10%)	No management planning has taken place	Very little or no conservation action taking place	negligible

Year	Protected Area	Designation	% overlap with IBA
1936	Yoshino kumano	国立公園	100
