Outline of Final Research Achievements

The objective of this study is to clarify the difference among species and elevation in N2 fixation in naturally established several Alnus species at the massive landslide area on Mt. Ontake, central part in Japan. The measurements were conducted at fixed-plots, which were set up at different elevations. The altitude of these plots was about 1100 m (Low site), about 1600 m (Middle site), and about 2000 m (High site). In this study, the N2 fixation was estimated as the fractional contribution of biologically fixed N to the absorbed N from the foliar δ15N data by 15N natural abundance method. The estimated N2 fixation was lower in A. hirsuta at Low site, which showed the faster revegetation rate, than those at High site. Alnus maximowiczii and Alnus matsumurae at High site showed no difference in N2 fixation. From these results, it was suggested that higher N2 fixation in Alnus species would be maintained even after 30 years after the disturbance.
