To investigate the possibility of using broadleaf trees for the future development of coastal forests, we constructed a simple experimental apparatus for developing wounds on the surface of leaves caused by blown sand, and conducted experiments on the effects of the type and area of wounds and the presence of wounds on the salt content in the leaves. The results of this study suggest that the appearance of scratches on the leaf surface is caused not only by the rubbing of branches and leaves by strong winds such as typhoons, as has been conventionally thought, but also by " blown sand impact " which causes dehydration of the leaves and salt intrusion. The findings are useful for the selection of broadleaf tree species to be used in future coastal forest development.
