Site details
Site description: The mouth of the Yahagigawa river area extends to the cities of Nishio and Hekinan. Since the present course of the river was created about 400 years ago, alluvial and a series of reclamation works have been made, resulting in the current geographic features. Along the dry riverbed areas with concrete embankments, Phragmites australis and other plants grow.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
