The author has investigated on the early stage of secondary plant succession in the campus of Chiba College of Health Sciense on a corner of reclaimed area along the coast of Tokyo Bay. The structure of the plant community from six years to ten years after denudation was charactristics as follows, (1) Physiognomy of the plant community was characterized by Phragmites australis and Solidago altissima through the 6 th-year into the 10th-year. (2) Plant species of 8 species belonging to 6 families were obserbed through five years in the plant community. Three perennial herbaceous species, Equisetum arvense, Solidago alttisima and Phragmites australis have grown before six years after denudation. After the 9 th-year, Pyracantha angustifolia of wood species, Miscanthus sinensis and Paedenria scandens of herbaceous perennials, and Visia angustifolia of winter annuals began to grow in the plant community. (3) Phragmites australis was markedly high in the degree of spatial occupancy (= the maxim plant height × the percentage of coverage) till the 9 th-year after denudation, but in the 10th-year that of Solidago alttisima and Miscanthus sinensis became higher together with Phragmites austraris. The structural changes of the plant community in this period will indicate the transition to more stable perennial herbaceous stage.
