Restoration of Kinu River (Tochigi Prefecture)

The river bed of Kinu River has been lowered largely due to a decrease of sediment supply and gravel quarrying. As a result, problems such as immobilized gut for ships, single-row-shaped shoals, a decrease of the flood frequency in the riverside, invasion and overgrowth of alien species such as eragrostis curvula occur and the original pebble riverside is being lost.
As it is important to conserve and regenerate the plants that grow on the pebble riverside such as aster kantoensis (one of the endangered species) in particular, a natural regeneration project is being conducted to restore the pebble riverside and the natural environment with aster kantoensis and create an environment where native riverside organisms can live and grow sustainably.
