Notes: Abstract The progress of growth of a subalpine youngAbies veitchii andA. mariesii forest during 25 years was analyzed on the basis of measurements of the processes of height growth of about 230 trees in a quadrat where the old canopy had been completely destroyed by a typhoon in 1959. The original forest floor sapling population had consisted of trees shorter than 2 m. Saplings grew faster after the breakage of the canopy than before,A. veitchii growing faster thanA. mariesii. During the 25 years of growth, a few well developed trees exceeded 6 m in height, while others remained around only 1 m or less. Some small trees, mostlyA. veitchii died at sites of high density. A bimodality in the distribution of tree height had developed with a trough at about 2.5 m, differentiating the trees into canopy and suppressed populations. Canopy trees grew with wide variation of rates, while most of the suppressed trees showed little recent growth. No difference was found in recent growth rates between the two canopyAbies species. Differences in height growth rates among individual canopy trees were analyzed on the basis of their horizontal crown overlapping. Competition models evaluating the difference in height between trees with overlapping crowns were shown to be effective. The height growth rate of a canopy tree appeared to be controlled by both the closely grown taller trees and the local density of trees including those shorter than the subject tree.

Notes: Abstract The process of revegetation on a subalpine mudflow was analyzed on the basis of the vegetation-soil relationship of the revegetated stands, and of the age structure and height growth process of the trees. Based on evidence derived from five independent sources, it was concluded that this mudflow was caused by a typhoon in 1959. The revegetated stands were classified into three vegetation types. AnAlnus maximowiczii stand was established where the surface soil was unstable; aBetula ermanii stand was established where the degree of disturbance by the mudflow was small; anAlnus-Betula stand was the intermediate type and occupied most of the area on the mudflow.Alnus had colonized concentrically 4–6 yr after the mudflow, andBetula and conifers had followed 1–2 yr later. As revegetation proceeded, the trees became differentiated into two populations, a canopy population and a suppressed one. The former was dominated mainly byAlnus and the latter byBetula and conifers. This differentiation was caused by the faster growth ofAlnus during the initial years of colonization. SomeBetula trees have recently grown faster thanAlnus, suggesting future replacement in dominance. Conifers have grown slowly even during recent years; the highly oligotrophic condition of the soil appears to have been responsible for this delayed growth.
