Description

A method of transplanting adult seagrass using facilities for reducing flow rates The present invention relates to a method for transplanting seagrass to improve the survival rate of transplanted seagrass by installing a facility to reduce the flow velocity and transplanting seagrass into the space behind it. Generally, seagrass, a type of marine flowering plant that flowers, is pollinated, and forms fruit, possesses a natural purification function in which its rhizomes and root tissues stabilize sediments and absorb and remove pollutants such as heavy metals. Furthermore, due to their excellent photosynthetic activity, seagrass habitats serve as spawning and nursery grounds for marine organisms. As they possess biodiversity and information regarding the coastal environment, they occupy an indispensable and important position in estuary and coastal ecosystems. However, recently, seagrass communities are being destroyed and various marine biological resources are declining due to marine pollution and indiscriminate coastal development in coastal fishing grounds, raising serious concerns regarding marine environmental conservation and fisheries resource protection. Therefore, to address these problems, active efforts to restore seagrass habitats are being made worldwide, including techniques for establishing seagrass forests by sowing seeds and improving the survival rate of transplanted seagrass. One method for improving the survival rate of seagrass transplantation is to transplant seagrass into a space formed by building a stone wall, as described in Patent Document No. 10-1018600. However, this method has the problem of high construction costs and time because it requires building stone walls and forming an inner space and a sediment layer. In addition, although a layer for drainage is formed, the overall form involves transplanting seagrass within the pond, which may result in poor seawater flow.

FIG. 2 is a schematic diagram of a seagrass forest formed according to an embodiment of the present invention. Figure 3 is an example of a grid seed sowing layer formed. FIG. 4 is a flowchart with an observation step added to an embodiment of the present invention. Figure 5 is a graph comparing the flow velocity outside and inside a flow velocity reduction facility.
