XVI International Botanical Congess

Individual, population and community dynamics of a cool temperate forest damaged by a record typhoon was examined by 42 years observation. Seedlings of Betula ermanii, Abies sachalinensis, Picea glehnii, P. jezoensis, existed as initial floristic composition. Survived and well-growth individual was established where it was away from or taller than the others regardless of the species. Although the dominant species has changed from B. ermanii to the conifer species, the four species coexist in canopy layer. The growth histories of the canopy trees were similar among species, and so shade tolerant species such P. glehnii showed potential ability of growth as same as fast growing species (B. ermanii). The regeneration trend supported the succession models presented recently.
