Norikura in central Japan with the aim of deriving basic information on the effects of grazing on vegetation. Some observatiens on basic differences such as changes of architecture ancl floristic composition of forests were made in cornmunities subjected to grazing and are herein

The major type found in the grazed area was further divided into two communities: one was characterized by a dense shrub layer hindering the growth of the herb layer, and the other showed less dominance of the shrub layer and a luxuriant growth of the herb layer. This reduction of the shrub layer was induced as an initial result of cattle grazing; nevertheless, the community was basically uniform in species compositien. Invasion of new species resulting in a change in floral composition of the forest was found only at the sites with canopy disturbance.
