To obtain ecological and phytosociological informations on the grassland vegetation in the uplands of western Honshu, Japan, the present investigation was carried out at 32 localities. The grassland in the region is a secondary vegetation which has developed on part of deforested and disturbed areas, and is distributed in the uplands at the elevation from 400 to 1400m, mostly from 700 to 1100m. The origin of the grassland dates back to the 18th and 19th centuries when forests of the uplands were cut except for those on the higher mountains. Major grassland types in the region are the tall grass type dominated by Miscanthus sinensis, the sod grass type dominated by Zoisia japonica, and the bracken type dominated by Pteridium aquilinum, among which the first two types are prevalent throughout the grasslands. The first type is always found at the mowing grassland and at the new grazing grassland, while the second type at the old grazing grassland. The last type is infrequently found in the yearly burned grazing grassland. These three types do not differ from each other in their vertical range.
