Studies on the distribution pattern of soil arthropods were carried in H.J. Andrews Expt. Forest. Forty-one species of Coleoptera in 14 families were recognized as the dominant group. Also, 7 species of soil mites in 6 families, Typhlodromus, Gymnodaeus, Phauloppia and Scleroribates were recognized without seasonal fluctuation, which made the difference to the outbreak pattern of the Palearctic region. Another species as 16 species of Collembola in 4, families, 16 species of Thysanoptera in 3 families, 10 species of Hymenoptera in 1 family, and 7 species of Acarina in 6 families were recognized. The result showed the importance of the soil arthropod as the primary decomposer in forest ecosystem and the relationship between species diversity and soil condition.
