Research Fund
Grant-in-Aid for Scientific Research from the Japanese Ministry of Education, Culture, Sports, Science and Technology
Other Information
250 m south from power generators (until February 2005) and 200 m west from unpaved road. There was a selection cutting in 1961 (15% of trees) in this experimental area. Some trees around the tower had been cut in advance, to prevent causing damage to the tower when trees were clear-cut. During January to March 2003, trees in the area of 13.7 ha were clear-cut. Preliminary research revealed that the total biomass volume of trees in this area was 2193 m3 (Koike et. al., 2001, Eurasian Journal of Forest Research, 2, 65-79) and this cutting removed the woods of 1203 m3 (ca. 19 tC ha-1) from this ecosystem. Sasa bamboos (the above ground biomass is 6-12 tC ha?1) under the snowpack had been kept intact during the clear-cutting period in winter, however in order to plant larch saplings, those were strip-cut into 4 m rows (a half of the clear cut area) seven month after the clear- cutting and just before the plantation (late October 2003). ca. 30000 saplings (ca. 0.04 tC ha-1) of 2-year old hybrid larch were planted in October 2003.
