Abstract
A demonstration experiment for tropical seagrass bed creation was carried out at Nakagusuku Port in the mainland of Okinawa. During past efforts, some parts of the created seagrass bed were washed away and their coverage was reduced. The reason for this was considered to be the environmental conditions of the sites. Therefore, this study was conducted with the aim of establishing the methodology for seagrass bed creation that enables the maintenance of the continuous growth of seagrasses. Based on the idea that it is necessary to remove the factors that limit the growth of the seagrass, submerged breakwater was installed and the seagrasses were transplanted together with the sands on which the seagrasses grew. The result of the experiment can be considered as the fact that the created seagrass bed continued to grow and expand even after three years, proving the viability of this methodology.
