“…Community components and community structure may change after the death of Sasa populations, because the light conditions on the ground surface are improved (Nakashizuka 1988;Makita 1992). The effects of simultaneous death on the vegetation have also been reported for other understory bamboos in temperate regions, such as Chusquea spp.…”

The recovery process of a Sasa tsuboiana population after a mass flowering and death in 1977 was investigated by 15 years of observation in the Hira Mountains, Kinki district, western Japan. Seed production was high (6600-13 800 seeds m -2 in Sasa plots and 3900 seeds m -2 in a forest plot) but m ), probably because of seed predation by Microtus emergent seedling density was low (14-21 seedlings -2 montebelli occurring between seed shedding and the next spring. The seedling density had decreased further by the next year and the S. tsuboiana population recovered from only a limited number of seedlings. In spite of such a low initial density, the S. tsuboiana population was able to regenerate successfully and attained the previous full stand height in 7-16 years. Miscanthus sinensis invaded and delayed the recovery of S. tsuboiana in one plot, but S. tsuboiana became dominant as it caught up with the height of M. sinensis.Seedling growth patterns, such as frequent tillering, the onset of rhizome extension in the early stage of seedling growth and frequent culm production from rhizomes, played important roles in the successful regeneration of S. tsuboiana.

“…A few reports have described the demographic features in the seedling population ofSasa kurilensis (Rupr.) Makino et Shibata (Kudoh & Ujiie 1990;Makita 1992) but no report has been published to describe the whole process from mass flowering to full recovery from the seedlings.…”

“…The species expands vigorously by layering on ground with a well developed soil, as dwarf-bamboo, Sasa spp. does (Makita, 1992), and can tolerate heavy shade (Hashimoto, 1991). The spatial correlation pattern between understory stems implies that T. dolabrata is a potential competitor of C. pisifera.…”

Stand structure and the regeneration of Chamaecyparis pisifera on sites with and without well-developed soil in an old-growth coniferous forest, Akasawa Forest Reserve, central Japan, were investigated, along with their relationships to other important coniferous species. Of stems of C. pisifera -> 5 cm diameter at breast height, stems with intermediate size were absent in stands on the developed-soil site, while those with smaller size increased in stands on the undeveloped-soil site, which supported a higher density of C. pisifera. In the stands without recent tree-fall of canopy stems on the developed-soil site, canopy stems of C. pisifera were distributed uniformly and the understory stems, patchily. On the other hand, both canopy and understory stems of C. pisifera in stands on the undeveloped-soil site were distributed patchily. In the understory, C. pisifera occurred as clonal patches formed by vegetative reproduction on various types of microsites including bare rocks. However, the clonal patches did not occur in a stand on the developed-soil site with dense saplings of an evergreen conifer, Thujopsis dolabrata, which can expand vegetatively with a well developed soil layer. Gap formation may induce C. pisifera to develop tree-form stems from shrubby clonal patches. On developedsoil sites, C. pisifera stands that survive a long disturbance-free period on this site need catastrophic disturbance for their regeneration, which will eliminate T. dolabrata in the understory and create bare soil for colonization of C. pisifera from seeds. On undevelopedsoil sites, C. pisifera replaces itself continuously by effective vegetative reproduction. Ground instability and the wet condition of this site may promote the replacement.

“…Makita (1992) attributed the mortality of juveniles of bamboo (Sasa kurilensis) plants to an imbalance in the DM economy: smaller genets suppressed by neighboring ones usually had a smaller photosynthetic organ, or lower leaf/stem ratio. In our study, the leaf weight within the interior of tussocks in the 7-cm defoliation treatment was only 60% of that in the 14-cm defoliation treatment.…”
