HASEGAWA, Jun-ichi (Sapporo-kosei Gakuen, Hokkaido) Altitudinal zones of the vegetation on Mt. Yotei, Prov. Shiribeshi, Hokkaido. From the investigations on the changes in distribution of trees and their quantity with the increase of altitude, four vegetation zones were recognized, viz. Pinus pumila zone at the altitudes of 1700〜1850m, Betula Ermani zone 1050〜1700m, Picea jezoensis-Betula Ermani zone 650〜1050m, montane broad-leaf forest zone 500〜650m. This zonation is caused by comparatively sudden alternation of one or two dominant species with altitude. But each species in general has its own distribution area and the plant communities change continuously with altitude.
