    Distribution of species in a W Japanese forest dominated by Fagus crenata and Abies homolepis was not related to gap size (10-340 m2). Seedling communities on tip-up mounds and those on fallen boles of coniferous trees were rich and composed of pioneer species. Understory composition in gaps without uprooting did not differ from undisturbed forest. Dwarf bamboo Sasa borealis which dominates the forest floor and prevents tree regeneration, magnifies the effect of uprooting. Species with small, wind-dispersed seeds were found mainly on disturbed soil; species with large, animal-dispersed seeds did not have any bias in distribution. Soil disturbance is a more important feature of the disturbance regime of this forest than is gap formation with regards to maintaining species richness. -from Author
