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dead leaves of each species to the nutrition of the poor soil at the timberline may be related to the amount nutrients withdrawn from senescing leaves.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.

富士山山坡的大部分地区覆盖着各种植被，海拔最高可达海拔约2,500m，但东南山坡的部分地区除外，该地区的植被正从完全受损的状态中恢复。由于最近的火山喷发。赤杨幼苗在盆中生长，并种植在富士山亚高山地区的土壤中。由于赤杨脱落的叶子具有较高的氮含量，这些叶子可能对林线贫瘠土壤的营养很重要富士山。每个物种的枯叶对林线贫瘠土壤营养的相对贡献可能与从衰老叶子中吸收的养分量有关。桤木是一种共生固氮植物，死叶中的氮浓度很高，在这方面可能特别重要。
