We have been conducting an field survey at Ishikari Bay New Port to observe the effects of port facility construction on seashore vegetation. It was found that a transition from stable to unstable seashore vegetation occurred 10 to 15 years after the completion of reclamation along the shoreline. During the reclamation, the volume of wind-blown sand entering the seashore vegetation communities was measured. This volume was found to be less at distances of greater than 100m between the vegetation communities and the port facility. Therefore, an increase in this distance could bring unstable seashore vegetation into a stable condition.
