The patterns of carbon cycling in the following two forests of Japanese beech (Fagus crenata) were studied ; one was a middle-aged forest with poor undergrowth and the other an old forest with abundant dwarf bamboos (Sasa senanensis) on its floor. The latter exceeded the former 16% in tree litterfall and 11% in soil respiration. The distinct difference was uncertain between two forests in both amount and vertical distribution of soil carbon. The net productivity including dwarf bamboo in the old forest was smaller than the middle-aged forest, while the annual litter supply to the soil was larger in the old forest. More than 1/4 of organic matter supply to the soil was associated with dwarf bamboos in the old forest, though the biomass of dwarf bamboo occupied only 1.5% in the total forest biomass. The contribution of dwarf bamboo on the carbon cycling in the beech forest was discussed.
