The studies were made on the relationship between the viable seeds present in the surface soil and the dung-pads and secondary succession of plant communities on "Umatateba" (viz. resting place in the rangeland). The total number of seeds recognized in the surface soils and the dung-pads on "Umatateba" were 1867 including 13 species, among which Hydrocotyle ramiflora, Zoisia japonica, Haloragis micrantha, Agrostis clavata, Carex nervata, Eriochloa villosa, Potentilla Freyniana, Carex albata, were generally shown. The plants of the numerous amount among the gatherd seeds were Hydrocotyle ramiflora and Zoisia japonica, being over about 50% together with their species throughout the investigation period. In paticular, the seeds of Zoisia japonica showed more than 33% of the total number in the dung-pads. From this result, the seed-populations in the surface soil and the dung-pads have been shown to parallel the expected opportunities for the vegetational changes on "Umatateba".
