In order to examine the pattern of forest response to gap formation, the species diversity and the floristic composition were compared in gaps and closed stands in a climax beech forest at Mt. Kurikoma, Miyagi Prefecture, northeastern Japan. Results showed that the vegetation in closed stands had the same values of species diversity as those in gaps, viewed from not only the species richness, but also from its equitability. Furthermore, the floristic composition was quite similar between gaps and closed stands. The above results strongly suggest that the regeneration process in gaps of a climax beech forest is a "reorganization" process of the vegetation established prior to gap formations. Thus, canopy gaps created in a beech forest hardly contribute to the persistence of pioneer species in a forest, but instead are indispensable for the regeneration of tree and subtree species which have pre-established juveniles in the forest floor of closed stands.
