| Outline of Final Research Achievements |
To elucidate the changes in the vegetation landscapes along the Uwa-sea region, I analysed the vegetation status of various farm environments and neighboring secondary forests, and anthropogenic influences on the distribution of Firmiana simplex, that has uncertain origin. After farmland abandonment, stone-walls became suitable habitats for several fern species. Historically less disturbed forests were important as habitats for some rare plants and as sources of dispersal of their seeds into abandoned terraces. Multidisciplinary analysis on the usage of F. simplex suggest that the plant was introduced along the region through the cultural diffusion of fiber usage and now distributed around specific villages. These results indicate that present diverse vegetation landscapes reflect the trace of human activity in the past couple of centuries.
