Abstract: We have been investigating actual conditions of a natural forest at Hokkaido. We set up some plots which area is about 0.2 ha (40m×50m) before 12 years ago for estimated forest growing stock. We surveyed them three times--1976, 1980, 1988. So, we report a change of forest composition during a measurement. Species which appeared in each plot were not changed. A number of stands in each times tends downward but the movements are slow. The growth of D.B.H. is difference between each diameter class. At a diameter class 30-48cm, a ratio of growth is higher than another class.
