Contribution from the Department of Vegetation Science, Institute of Environmental Science and Technology, Yokohama Natlonal University, No.4.A synecological study of shelterbelt plantations was conducted near Habuminato village in the southpart of Oshima Island, Oshima-cho, Tokyo. The shelterbelts, including windbreak forests, hedgerows, and avenue plantations are situated near the villages and fields. They always consist of evergreen broad-leaved trees and shrubs, and are about 8 to 18 meters high. They are classified phytosociologlcally into the following three types. 1) Daphniphyllum teijsmannii-Cinnomomum japonicum type consists of many indigenous trees and shrubs developing in rather old villages. 2) Camellia japonica type is mainly planted along the roads in or between villages. 3) Pasania edulis type is composed of Pasania edulis, transplanted from southern Japan, and is lacking some indigenous species. These three types of shelterbelt plantation protect the village effectively against wind storms and salt spray throughout the year. Both Daphniphyllum teijsmanni-Cinnamomum japonicum and Camellia japonica seem to be more appropriate in this village because they have many indigenous species and coincide with the potential natural vegetation. The blossoms of camellia (Camellia japonica) attract tourists in the early spring. The seeds of camellia are used to produce oil.
