To understand the ability of sediment trap to trap fine particle soils, I examined differences in the particle size composition between soils trapped by sediment traps in two time periods (August and October) and surface soils of forest floor in three sites of sugi (Cryptomeria japonica) and hinoki (Chamaecyparis obtusa) plantations with different surface geology. In the soil trapped by the sediment trap during the study period, the proportion of soil that consisted of particle size smaller than the sediment trap net mesh size was about the same as that of the surface soil. Multi-response permutation procedures hardly detected any difference in particle size composition between the soil trapped by sediment traps and surface soils in this study. This confirmed that the particle size composition of trapped soil in the sediment trap is almost similar to that of surface soils.
