Outline of Final Research Achievements |
Forest canopy dynamics over the past 30 years were elucidated in 17 montane forests in the central to northern part of the Honshu Island in Japan. We measured the changes of canopy area by analyzing the past arial photos and the photos took by drone for this time together. The results showed that the average annual rate of change in the canopy area of conifers was positive in many sites, while the rate of change in the canopy area of deciduous broadleaf trees was positive in some sites and negative in others, over a 30-year period from the 1980s to the 2010s. We also found that the factors affecting the rate of change in tree distribution were different at the upper and lower limits of the distribution.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、日本の冷温帯山地林で、過去30年間での樹木の分布変化速度を推定し、それらを決定する要因を明らかにした。これらの成果は、森林衰退など脆弱性評価、森林に対する気候変化適応策の具体的手法などに関する基礎的知見を提供するのみならず、生態系適応策の社会的意義やその適用時期、優先順位などを現実的に明確にするためにも重要である。
