Abstract
Coastal vegetation establishment on new beach formed by dike set back from the shorelines was investigated by field observations on the Isewan-Seinan Coast for 4.5 years. It was observed that during the first 3 months, non-coastal plants appeared and rapidly spread out to cover almost the entire beach surface. Subsequently, coastal plants invaded the area and gradually increased their expanse. This shift in the nature of vegetation was observed to be more rapid in areas that experienced active wave run-up than in areas that were relatively shielded from waves. Estimates of the wave run-up experienced during the study period revealed that the wave wash disturbances were effectively promoting the establishment of coastal vegetation.
