The aboveground biomass in Hinoki（Chamaecyparis obtusa Endl. ）plantation following slush-and-burning were measured and compared with the general treatment plantations during ten years, in Okuizumo, Shimane Prefecture. The growth of Hinoki planted in burning plots was superior to that in general plantation plots. The aboveground biomass of Hinoki in ten year after burning were５０．６and１１．８t/ha on the lower and upper part of slope, respectively. These were three times as much as those in general plantation plots. The natural regeneration of Japanese Red Pine was observed in every plot. The amount of biomass was apparently larger on the upper part of slope in burning site. The recovery of other tree species consisted of both seed and sprout regeneration in clear-cutting sites. The aboveground biomass of the upper part dominated by the latter was more than two times as that of lower part of slope. The biomass of herb and grass on the lower part was largest in４years after burning and decreased with the growth of Hinoki.
