| Research Abstract |
The analysis of aerial photograph and investigation of vegetation structure indicated that the forest-limit of Mt. Fuji was moving upward through the vegetation development into the volcanic desert and destruction of vegetation by avalanche. Establishment of the seedling of larch, a dominant early-successional tree species, depended on a nurse-plant effect of a pioneer dwarf species. Avalanches frequently disturbed the succession in the forest-limit by a drastic change of light-, moisture- and soil-conditions, which limited the photosynthesis, growth and survival of late-successional species.
