 note = {application/pdf, Soil animals and aquatic macroinvertebrates were investigated along the Sunaoshi River in Kamakura City and Todoroki Valley in Tokyo, which represent urban green areas with stream. The soil animals were collected qualitatively by Tullgren funnels and the aquatic macroinvertebrates were collected quantitatively by Suber sampler （38 mesh）as well as qualitatively by D-frame aquatic net and sweeping net. The soil faunas in both the areas were unexpectedly rich, being characterized by Amphipoda, Diplopoda, Opiliones, Crustacea（Ligiidae）and Coleoptera （Pselaphidae), which are considered sensitive to nature destruction （Table 1）. Among the soil animals oribatid mites were identified on species level to find a total of 73 species, 54 along the Sunaoshi River and 42 along Todoroki Valley, including each 14 species which indicate well reserved natural environment （Table2）. Existence of Parachipteria distincta (Aoki), Licnodamaeus undulatus （PAOLI） and  Cosmohermannia frondosa Aoki et Yoshida are noteworthy. The river condition of the Sunaoshi River at the upper sites was good with high values of SHANNON’s diversity index （3.00-3.13）and low values of pollution index （0.00）, while the condition of the Sunaoshi River at the lower site and Todoroki Vally was bad with lower values of diversity index (0.72-2.01）and high values of pollution index （0.50-0.83）（Table 3）. The number of species were not so large even at the upper sites of the Sunaoshi River, but the aquatic fauna was consisted of species intolerant of organic pollution, excepting Asellus sp. The Asellus is known as tolerant of pollution, but it often appears in unpolluted small river sand streams in hill areas of Kanagawa Prefecture and is considered to be inappropriate as indicator species. Existence of Ephemera japonica MACLACHLAN and Neoprla niponensis （MACLACHLAN）is noteworthy. The number of species at the lower site of the Sunaoshi River and Todoroki Valley was small（6-7 species) and the fauna comprised of tolerant species such as Chironomus yoshimaisui MARTIN et SUBLETTE and Tibuficidae.},
