The dynamics of current seedlings, mainly Cryptomeria japonica, were studied under different canopy tree densities in a cool-temperate forest at Ashu, Kyoto in 1979 and 1980. Most seedlings germinated early in the growing season. Germination was mostly dependent on the amount of rainfall, and most mortality was caused by predation and drought. The survival rate of Cryptomeria japonica seedlings was similar in 1979 and 1980. A larger number of seedlings germinating meant a larger number seedlings established. The probability of death for seedlings was higher in the early growing stages, and dead seedlings reaching to later growing stages were very few. These results reveal that germination of Cryptomeria japonica in this stand is greatly enhenced by rainfall, rather than temperature and current seedlings growing quickly lead to their higher survival rates.
