Abstract
We investigated the structure of woody seedling population in the restored urban forest, "Inochi- No-Mori" in Kyoto city for five years since construction and examined the growth characteristics such as recruitment, height growth and mortality rates of each species. On the whole, evergreen broadleaved species had low recruitment, high height growth and low mortality rates. On the other hand, deciduous broadleaved species had high recruitment, low height growth and high mortality rates. Acer palmatum and Ligustrum lucidum had the highest height growth rates when the relative solar radiation was 10-15% and 15-20% respectively. In contrast, Quercus acutissima had lower height growth rates. However there were no significant differences in mortality rates among species, Q. acutissima had relatively lower mortality rates. Nevertheless L. lucidumi, invasive alien species had not been planted in Inochi- No-Mori, recruitment rate of L. lucidumi seedlings was 2.0 individuals /100m2/year on average when there was no seed source of this species within 10m radius. Celtis sinensis and Aphananthe aspera had the highest recruitment and low mortality rates. It indicated that C. sinensis and A.aspera might have suitability for this site and the population densities of these species would be greater in the future.
