Many studies for improvement of the persistence of red clover population (Trifolium pratense L.) are carried out for extension of the survival period of individuals, or improvement of a physiological function. In this study, we focused on 1) effect of natural seeding to sward production of red clover, and 2) spatial and temporal dynamics of red clover population in small scale. On first cutting time in 1999, many recruitment plants were observed in the late cutting meadow plots. In first cutting time in 2000, their dry matter weight were increased to 50% of parental plants. The parental plants in late cutting plots have higher mortality than standard cutting plots. We suggested that it may be the trade-off between the sustainability of parental plants and recruitment plants production. In red clover pure stand we surveyed, spatial distribution patterns of individuals have been aggregated temporally in small scale.
