Restoration of Ishikari River (Hokkaido)

Ishikari Plain has been changed to a vast agricultural land by embankment works and the agricultural land development conducted since the Meiji Period. As a result, the wetland spread in the low-lying area of the basin and the forests along the river were lost, the shape of the river was simplified and the ecological environment was dramatically deteriorated.
In order to regenerate the lost river environment of Ishikari River, pools are being constructed (which are or will be connected to the main stream when the water level increases) to diversify the river, restore the wetland environment and regenerate the forest environment at the meeting point between Ishikari River and Tobetsu River, a tributary river.
