Fig. 4. Average DBH change over time in the Korean white pine planation and oak-dominated natural deciduous forest. Only the trees that survived the entire measurement period were analyzed. The plots were thinned with different intensities at the first measurement period: Plot A with heavy thinning treatment, Plot B with moderate thinning treatment, Plot C with light thinning treatment, and Plot D with unthinned treatment. Specific thinning intensities are provided in
Table 2. DBH: diameter at breast height.
