| Outline of Final Research Achievements |
To analyze the Eco-DRR function of coastal dunes, we evaluated the stability of dunes and vegetation on the Tottori dune beach. In the long term, the direct changes caused by human influence were significant. Ten years of sand movement within the dune showed that sand tended to accumulate where plants grew, and non-native plants tended to grow in areas where sand movement was small. No short-term vegetation changes were observed during the study period. It was considered that native plants have the function of supplementing and depositing sand in coastal dunes, and may contribute to maintaining and improving the Eco-DRR function of the dunes.
