Phytosociological studies of the hedgerows in rather old villages were conducted in the Amami islands of southwestern Japan in 1988. Three types of hedgerows were recognized ; 1. Ficus-virgata-Ficus microcarpa type, 2. Garcinia subelliptica type, and 3. Viburnum suspensum Fraxinus insularis type. Based on more widely surveyed materials, these types were classified through species combination into the following three hedgerow groups. A. ficus virgata group, characterized by Ficus virgata, Viburnum awabuki etc. and occurring young limestone soil originating from elevated coral reefs. B. Viburnum suspensum-Podocalpus macrophyllus group, classified by the Presence of Podocarpus macrophyllus and Viburnum suspensum, and found on well weathered soil on old limestone. C. Codiaeumt variegatum-Bougainvillea spectabillis group, Characterised by ornamental garden species and planted in the developed towns and cities. The distribution of these first two hedgerow groups seems to correspond to the potential natural vegetation.
