| Research Abstract |
The greatest part of the slope of Mt. Fuji is covered with various types of vegetation up to a height of about 2,500m above sea level, except for part of the south-eastern slope where the vegetation is in the process of recovery from total damage by the latest volcanic eruption. Seedlings of Alnus maximowiczii were grown in the pots and they are planted in the soil on subalpine zone of Mt. Fuji.
As the shed leaves of Alnus had high values of nitrogen content, these leaves might be important to nutrition the poor soil at the timberline of Mt. Fuji. The relative contribution of dead leaves of each species to the nutrition of the poor soil at the timberline may be related to the amount nutrients withdrawn from senescing leaves. Alnus, a symbiotic nitrogen-fixer which has high nitrogen concentration in dead leaves, may be particularly important in this respect.
