The population dynamics in a whole process of regeneration was studied in a climax beech forest at Mt. Moriyoshi, Akita Prefecture, northeastern Japan. The change of biomass and the survivorship of beech in the process were clarified. Three phases were distinguished by the structure and the features of the regenerated populations in the process. In the initial 10 years or so, the density of the population was increased by the recruitment (phase I). After the population attained the full density state, the density decreased rapidly with the fast growth of trees (phase II). When the biomass of the population approached the maximum asymptote (within 70-80 years after the gap formation), the decrease of density slowed down (phase III). These three phases corresponded to the gap, building and mature phases, which were described by WATT (1947) and WHITMORE (1982).
