Abstract
Sprouting that occurs after clear cutting of seven tree species commonly observed in broad-leaved secondary forests in the warm-temperate zone was investigated in Hyogo prefecture, Japan. The environmental factors affecting the sprouting ratio after one growing season and the survival rate of the sprout after three growing seasons were analyzed using a generalized linear mixed model. In Quercus serrata, the sprouting ratio was lower on drought-prone slopes, in short stumps and in old trees. On the other hand, the survival rate of stumps was higher on tall stumps. The older the tree, the lower the sprouting ratio in many tree species examined. This trend was most prominent in Quercus serrata. These results suggest that sprouting of Quercus serrata is sensitive to aging and that the survival rate of sprouts may be increased by controlling stump height.
