| Outline of Final Research Achievements |
In Shizuoka prefecture, Japan, farmers traditionally cover furrows in green-tea fields with grass (mainly Miscanthus sinensis and Pleioblastus chino) in the autumn and winter seasons. The semi natural grasslands from where this grass is collected are called Chagusaba. This fact is interesting because, in Japan, the area covered by semi-natural grassland is decreasing, and some natural plants found in semi-natural grasslands are now endangered. In contrast, Chagusaba provide an important habitat for natural plant species of semi-natural grasslands. In this study, we found that differences in site environment and management methods have a significant impact on biodiversity. Based on our results, we have proposed an ideal way of maintenance and management of Chagusaba in order to preserve its biodiversity for the future. These results were evaluated and adopted as an excellent example of coexistence with nature in elementary school textbook published nationwide.

| Academic Significance and Societal Importance of the Research Achievements |
「茶草場」は、農業によって維持される生物多様性の豊かな草原（半自然草地）であることから「世界農業遺産」に登録された。この「茶草場」の存在は、申請者らの研究によって最初に報告されたものである。茶草場は農家の草刈り管理によって維持される。茶草場を維持していくためには、農家の草刈り管理が適切に行われることが必要である。しかしながら、茶草場の生物相は地域によって異なり、このような生物相の違いは茶草場全体の生物多様性に少なからず貢献していると考えられる。本研究の結果、茶草場の地域間の多様性の要因が明確されれば、今後の世界農業遺産の適切な管理に対して、重要な示唆を与えるものと期待される
