In consequence of TWINSPAN, which is the classification method of plant communities, six communities were classified as 1) Mangrove, 2) Vigna marina - Bidens pilosa var. radiata community, 3) Scaevola taccada - Heliotropium foertherianum community, 4) Thespesia populnea - Pandanus community, 5) Hibiscus tiliaceus - Derris trifoliate community, 6) Enhalus acoroides (Sea grass) community. Mangrove forest was mainly established on a salty swamp located on the small river mouth or coastline. V. marina - B. pilosa var. radiata community, S. taccada - H. foertherianum community, and T. populnea - Pandanus. community established on the sandy seashore. And, the H. tiliaceus - D. trifoliate community was observed around the rocky coast. Vegetation patterns on an island differ among three islands. Mangrove and H. tiliaceus - D. trifoliate community established in Weno and Romanum island, but not in Piis. This pattern seems to be the effect of the geology of the island, i.e., base-rock type may relate to habitat formation in the coastal area. On the other hand, V. marina - B. pilosa var. radiata community that includes many invader plants was established only around the town in Weno island. This community may depend on the industrial human activity. To recognize the mechanisms of formation of vegetation on islands, we need to clarify several environment factors related to geology, sociology, and economy.}, pages = {7--17}, title = {Floristic composition and distribution pattern of coastal vegetation in Chuuk island, Federated States of Micronesia}, volume = {53}, year = {} }
