| Outline of Final Research Achievements |
We researched the impact and the recovery process for vegetation by tephra fall using pollen analysis. We detected that the vegetation was affected by environment change and human activity, but could not detect the influence for vegetation by tephra fall. Tephra of a few cm may have no influence on the vegetation. But, the plants with a height of several cm should have had a great influence. The pollen production of these plants is very low. Hence, there is a possibility that the fossil pollen grains of these plants could not be detected in pollen analysis. Hence, it is thought that it is necessary to increase the measurement number of fossil pollen grains. In Barasantou, the possibility of migration of volcanic glass particles was shown. The impact and the recovery process for vegetation of the eruption interval for several decades seems to be disturbed. To evaluate the impact of vegetation by tephra fall, it is suggest that further high-resolution analysis may be necessary.
