Lakes Komuke and Shibunotsunai


IBA Justification

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 Current IUCN Red List Category Season Year(s) Population estimate at site IBA criteria met
Eurasian Wigeon Mareca penelope LC passage 2003 present A4i
Northern Pintail Anas acuta LC passage 2003 present A4i
Whimbrel Numenius phaeopus LC passage 2003 present A4i
Red-necked Stint Calidris ruficollis NT passage 2003 present A4i

The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2004).
