| Outline of Final Research Achievements |
The objective of this study was to clarify the role of landslide on regeneration of a cool-temperate forest. I investigated tree seedling dynamics on landslides triggered by heavy rain in August 2013 and neighboring undisturbed forest floor. The landslides promoted seedling establishment of several canopy component species in 2014. Seedlings of small seeded species, Cryptomeria japonica and Betula maximowicziana, were recorded only in the landslide-disturbed area. However, these species did not become dominant because of insufficient seedfall and poor survival. It is suggested that difference in soil water content among disturbance types within the landslide-disturbed area caused variation in growth of the seedlings and development of understorey vegetation.
