Halophyte vegetation of Kaki-Jima is characterized by the islet composed of the natural oyster beds. The first ecological report of this vegetation was made by TATEWAKI and YAMANAKA (1939), they divided the communities into three sociations. That is; 1) Elymus mollis-Senecio pseudo-Arnica soc. ; 2) Triglochin marilimum-Glaux maritima soc. ; 3) Aster tripolium-Puccinellia kurilensis soc.. According to the result of the investigation in 1955,the total number of the islet is about 10 at low tide. Among them, the plant growing is only limited in two islets, in spite of the former report recorded the plant grew in six islets. Influence of floating ice and wave action has disrupted the communities and that successional trends. In 1955,the Elymus mollis-Polygonum aviculare var. vegetum soc. was found and substituted by the Elymus mollis-Senecio pseudo-Arnica soc. Salicornia europaea communities invaded in the salt marsh. It was noticiable that Aster tripolium-Puccinellia kurilensis soc. was rather widely extended. On the final changes, the succession of these communities may be led to a single community composed of Triglochin maritima sociation.
