抄録

A forest on Ikishima Island in Ako, Hyogo Prefecture, is one of the largest and richest lucidophyllous forests dominated by Castanopsis cuspidata, Actinodaphne lancifolia, Cinnamomum japonicum, Camellia japonica, Quercus glauca, Ternstroemia gymnanthera and others in Hyogo Prefecture. This forest has been preserved by the residents in Sakoshi, Ako, as the sanctuary of shrine Osake-jinja, and was designated as a natural monument by the Agency for Cultural Affairs. Nevertheless, by the extraordinarilly luxuriant growth of the vine Stauntonia hexaphylla, the forest canopy has been seriously damaged since the 1970's. We concluded that it is necessary to manage the forest immediately. For the purpose of restoring the original forest canopy, Stauntonia hexaphylla vines were cut by citizen participation on February 16, 2002. We reported this procedure of the vegetation management of lucidophyllous forest on Ikishima Island.
