Since 1959, Authors have studied a production structure of Shirakashi coppice forest by inventory data of permanent plot at Shimoyamasa, Hirose cho, Shimane Prefecture.
This paper reports change of forest structure, volume increment and increment of stem dry weight of this stand in the third cutting cycle. 1. After selection cutting in 1965, the sprouts shot from almost all stamps, and the regeneration succeed. The change process of the structure of this stand were shown in Table 3 by statistical analysis of diameter distribution. 2. The current annual volume increment of this stand amount to 15.7m^3 per ha (rate of increment was about 21.6%). The remaining trees above medium class (D. b. h. 7 cm and over) have produced the major part (approximately 65%) of the total increment. The annual yield in the 3 circulation-periods was 12.3m^3 per ha. 3. The biomass were estimated by sample trees, and the current annual dry weight of stem at the cutting cycle amount to 11.6 ton per ha (rate of increment was about 22.5%). |
