| Outline of Final Research Achievements |
In this study, we studied the community structure of mycorrhizal fungi, endophytic fungi, and nematodes that live in and around cedar fine roots in human-planted artificial forests, in the central region of Japan, focusing on Japanese cedar, which is an endemic tree species in Japan. Our results showed that a diverse of fungi coexist within the roots, and that nematodes are likely to feed on them. These soil organisms were strongly influenced by the acidity (soil pH) of the surrounding soil. Therefore, the soil environment in which cedar plantation forests are established may affect the diversity of microorganisms living in the soil.

戦後に植栽されたが管理が行き届かない人工林が散見されるが，そうした中には健全な生育の見込めない林もある．本研究では人工林であっても多様な土壌生物がいることを見出し，その暮らしは生産者である樹木とともに，樹木がよりどころとする土壌環境に影響を受けることが分かった．今後，これらの微生物，線虫が林の健全性を示す指標となるのかどうかの視点に道筋をつけることができた．
