Abstract
Potentilla discolor Bunge was grown in the research farm, and population dynamics of seedlings were investigated for three years. It was revealed that seedlings were found intensively within 60 cm around plants which produces mature seeds. The fact indicates that seeds dispersal distance were short. Many seedlings had died within one year after germination, whereas the survival rate of the seedlings which lived more than one year were high. Seedlings were often found in nearly bare areas than in high vegetation covered areas. These results suggest that ground management which can provide sparsely vegetation cover safe site is vital in conservation populations through regeneration from seedling.
