At higher elevations on Mt. Asakusa, one of the mountains characterized by deep snow accumulation in Japan, the relationship between snow depth and the distribution pattern of plant communities was studied in connection with topographical conditions. Dwarfed Fagus crenata forests in the northwestern〜western part (N〜W slope), and scrubs and meadows in the southern〜eastern part(S〜E slope). The snow depth in meadows was the deepest among the four plant communities, and that in scrubs was deeper than those in Fagus crenata forests and dwarfed Fagus crenata communities. However, little difference in snow depth was found between Fagus crenata forests and dwarfed Fagus crenata communities. Therefore, it is difficult to explain the distribution of plant communities only by the snow depth. It is presumed that topographical conditions affect not only the distribution of snow depth but also the effects of the snow on plants, and that consequently the distribution pattern of plant communities is determined through the influence of the topography.
