| Outline of Final Research Achievements |
In this research, I aimed to conservation and restoration of salt marshes that provide important ecosystem services to us. I attempted to evaluate the species diversity of them with high marsh zones, which have not received much attention so far. The results suggest that salt marsh patches with a high marsh zone connected to the land area have a high species diversity of benthos that utilize salt marshes. Moreover, I attempted to classify the salt marsh ecosystems, resulting that they can be classified into six types with different aquatic fauna and physicochemical environments.

| Academic Significance and Societal Importance of the Research Achievements |
近年では自然環境の定量評価が試みられており，河川に現存するヨシ原もその1つである．本成果では，ヨシ原は生物相から6つに細分化されることを示した．つまり，ヨシ原の面積の定量評価が各地で行わる際には，「ヨシ原」という単一項目からより解像度を上げて定量評価をする必要性が強調される．言い換えると，本成果に基づき，効果的なヨシ原の定量評価が期待される．また，陸域との接続性が高い種多様性の維持に必要であることが示唆されたことから，地盤の高さに配慮した塩性湿地の自然再生が今後期待される．
