Restoration of Fushino River mouth and tidal flat (Yamaguchi and Ogoori Town, Yamaguchi Prefecture)

In the mouth of Fushino River running through Yamaguchi City, a vast tidal flat spreads, which is one of the greatest tidal flats in the West Setouchi region. It attracts migrant birds and it was selected as one of the 500 important wetlands in Japan.
However, due to the floating mud flowing in from the middle and upstream basins and the delay in taking domestic sewage countermeasures, oystershells were built up, the muddy tidal flat area was expanded and the biomass of fish, crabs and wild birds was decreased. To address this problem of the tidal flat ecosystem alteration a “framework to create a rich basin of Yamaguchi (Fushino River model)” was drawn up through collaboration between industry, educational institutions and the administration in March 2003. Today, the organizations concerned are cooperating to regenerate the tidal flats and create Zostera beds on a trial basis and wild bird research and beach cleaning is being performed.
