The change of the stand structure and the volume increment of the coppice forest of "Shirakashi" in the fourth and the fifth cutting cycles (1969 - 1979) were investgated at the Shimoyamasa permanent plot set up in Hirose Cho, Shimane Prefecture in 1959. The forest has been managed by the selection method.
The change processes of diameter distribution in two cutting cycles were shown in Table 3. After cuttings in 1969 and 1974, almost every stumps reproduced sprouts, and regeneration of forest succeeded during this work. The current annual volume increment in each cutting cycle amounted to 15.7 m^3 and 13.0 m^3 per ha., respectively. The remaining trees over 7 cm D.b.h. produced the major part of the total increment. |
