Germination and distribution of buried seed in floodplain

Abstract

In order to discuss the conservation of endangered species and the restoration of vegetation in a river flood plain, we conducted germination tests and vegetation and site condition surveys, which included ground-water level and submergence frequency data. Since ground-water level and submergence frequency depend on the height of the ground, moisture conditions in the area investigated are strongly influenced by the height of the ground. In addition, since there is a close relationship between the distribution of existing vegetation and the characteristics of the germination of buried seed, the species composition of existing vegetation is decided by differences in the moisture condition when buried seed germinates.
