概要

The Fujimidai Heights are located in the subalpine zone of Central Japan. The upper area of the heights has been used as pasture, being surrounded by the climax coniferous forest of Picea hondoensis and Abies veitchii. The climate of this area is cool and humid with a high annual precipitation of more than 2,400 mm. In this pasture four vegetation types are found. A Carex oxyandra community has developed on the moist and mesic land. A Festuca ovina community has developed on the dry ridge. Both the above are under heavy grazing and have thus developed as biotic plagioclimaxes from the wind-swept Sasaella sasaelloides community. Finally a Calamagrostis conoderuts var. langsdorfil community is found in the light grazing land and a Sasaella sasaelloides community has developed on the abandoried area. There are few pastures and meadows in the subalpine zone of Japan, but the Festuca ovina community under grazing and the Calamagrostls longiseta community under mowing are found in the Utsukushigahara Heights located in the subalpine zone with low annual precipitation. It is considered that the floristic composition of grassland vegetation in the subalpine and subarctic zone is affected not only by air temperature but also by the water condition of the habitat.
