Site details


Site description: The site consists of a sandy and muddy tidal flat, reed beds and small sized saline wetlands. The tidal flat is surrounded by embankments and towards the inland is the flood control basin, paddy fields, farmlands and derelict eel ponds. The tidal flat of Toyohashi City side is composed of sandy and muddy substances, while the tidal flat in the Tahara City side is more muddy, where oyster reefs are formed. In the saline wetlands grow rare seaside plants. Along the largest river Shiokawa, the basin is occupied by reed beds.
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.
