The regeneration process of Castanopsis cuspidata var. sieboldii Nakai and Persea thunbergii Kosterm. was studied in an evergreen broad-leaved climax forest on Miyake-jima, Izu Islands. In this forest, C. cuspidata var. sieboldii was a dominant tree species, especially in patches of mature-phase forest. However, in patches of young-phase forest, P. thunbergii and C. cuspidata var. sieboldii were co-dominants. There were more saplings (<0.5m in height) of P. thunbergii than those of C. cuspidata var. sieboldii. The latter's canopy trees had large crown areas and many sprouts reaching the canopy layer. The repair process in two small gaps involved canopy expansion of C. cuspidata var. sieboldii and a few other species. It seems that sprouting and canopy expansion are advantageous to the survival of C. cuspidata var. sieboldii in the canopy layer, and that this may compensate for the low regeneration ability from saplings. On the other hand, P. thunbergii seems to regenerate from saplings more frequently than C. cuspidata var. sieboldii, but may not survive as long as the latter in the canopy layer. Consequently, P. thunbergii seems to be able to dominate only in patches of young-phase forest in the regeneration complex of the climax forest.
