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'):Species | Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Japanese Woodpigeon Columba janthina | LC | resident | 2003 | present | A2 |
Japanese Murrelet Synthliboramphus wumizusume | VU | breeding | 2003 | present | A1 |
Pleske's Grasshopper-warbler Helopsaltes pleskei | VU | breeding | 2003 | present | A1 |
The current IUCN Red List category (shown above) may differ from that which was valid at the time of IBA criteria assessment (2004).
