This report deals with the results of the investigation on areas of stock ranges in Hyogo Prefecture in 1957 for the purpose to classify the grassland communities, and to analyse the relation between the communities and top soil characters or elevation of slopes. The results are : (1) Sampling plots consisted of 62 plots, and were investigated by the line interception method (10m) and the nest quadrat method (1m^2). The dominance was expressed as (coverage ratio+frequency ratio)/2 (2) The plant communities may be grouped into six types, as follows : one, Miscanthus type, two, Arundinaria type, three, Pteridium type, four, Miscanthus-Pteridium type, five, Arundi-naria-Miscanthus type, and six, Arundinaria-Pteridium type. (3) The value of the Km index among plants shows a close relation-ship between Miscanthus and Lespedeza (100) given in Table 1. (4) At higher elevation, the bush is open, and Miscanthus grows in every elevation, but on the other hand Pteridium only in areas of low elevation. (5) The yield of native plants seems to decrease from below upwards on the slope. (6) The effects of soil characters on the plant communities are shown in Table 8.
