Mechanisms maintaining species diversity in managed meadows are not still well understood. To assess the effect of several important factors on species composition of meadow communities, species regeneration abilities were studied in the course of several years. The research was based on manipulative experiments, where species establishment and survival in seed addition experiments as well as during natural regeneration was observed. By comparison of species establishment in intact and disturbed vegetation, effect of dispersal limitation, abiotic conditions and competition was assessed as well as regeneration ability of different functional groups.
