THE FRAMEWORK TO REHABILITATION OF THE ARIAKE SEA AND THE YATSUSHIRO SEA

Recently, coast environment in the ARIAKE sea and the YATSUSHIRO sea is getting worse. The cause is the decline of the water quality self-cleansing function and reduction of biological diversity by the reclamation and so on. Kumamoto Prefecture established the committee aiming at rehabilitation of the coast in 2004, and has had a discussion for two years. The work was pioneering the reproduction for a closed sea and decides upon the statement of coastal rehabilitation. We adopted the two technique newly. One is to have divided the characteristic of the coastal region by the character of the intertidal, the hinterland and the seashore area of the distribution of the halophilious plant and so on. The 2nd complemented the lack of the scientific data with the interview survey, as a result, we found the distribution of seagrass (Zostera marina Linnaeus) in the past in YATSUSHIRO sea. It wants to introduce the process of these efforts and gotten new knowledge at this article and we consider about the spread of the reproduction in the future.
