Abstract
Numbers and biomasses of soil macro-animals were investigated in a natural mixed stand of fir and hemlock in the Wakayama Experimental Forest of Kyoto University in Wakayama prefecture. Numbers were composed of earthworms, millipedes, centipedes, spiders, wireworms and dipteran larvae. Numbers and biomasses were estimated at 68.3, 3.0g (wet weight) per quadrat (50cm×50cm) in May, at 57.4, 1.5g in August; and 53.6, 1.0g in November. The rapid decrease in biomass from May to November, attributable to the decrease of earthworms. (Tab. 1, 2) Numbers and biomasses of soil macro-animals in the mixed stand of fir and hemlock lay between those of subarctic coniferous forest and temperate deciduous broad leaved forest. Animals decreased with increasing depth. Although no animals were collected below a depth of 40cm in May, a few were collected below a depth of 40cm in August and in November. (Fig. 2, 3) Biomasses become smaller in proportion to the amount of A0 horizon accumulated and on other hand larger in proportion to the average decomposition rate of A0 horizon and results from the mixed stand of fir and hemlock lay between subarctic coniferous forest and temperate deciduous broad leaved forest. (Fig. 5, 6)
