Regeneration process of a beech forest under the influences of grazing was studied at Mt. Moriyoshi, Akita Prefecture, north-east Japan. Beech saplings were abundant on the floor because of grazing on the dwarf bamboo Sasa. The small and middle size trees had a contagious distribution, and most of them in the same contagion seemed to have emerged within a 20-50 years period before or after gap formation. This partial regeneration of the forest took place in gaps which originated from the falling down of a single or a few trees. The resulting forest structure is fundamentally similar to that of the Kayano-Daira area. Beech seedlings can survive about 10 years, but grow scarcely under a well closed canopy. It was discussed that successful regeneration of beech forests requires sufficient seedling banks and gap formation.
