| Outline of Final Research Achievements |
Forest floor vegetation is important to the maintenance of forest productivity and biodiversity.Thinning promote the development of the forest floor vegetation in plantation.Previous studies in Europe and North America, where thinning is highly mechanized, has reported. There are little studies for verifying the traffic effect of forest machine on forest floor vegetation in Japan. Our pilot study aims to understand the effects of machinery traffics on forest floor vegetation in Abies sachalinensis (AS:main silviculture species) plantation.
Soil compaction by vehicle traffics, candidate factor of vegetation inhibition, was verified.The generation of soil compaction, and recovery were revealed in AS plantations. The influence of the machine traffics to the vegetation development was also revealed. Suppression of vegetation development by the machine traffics was not observed. While, convergence of species composition was observed.
