Fig. 3. DBH distribution by thinning intensity over measurement instances for each site in the Korean white pine plantation and oak- dominated natural deciduous forest. Only the trees that survived the entire measurement period were analyzed. DBH class was 2 cm of bandwidth. Each site and plot were thinned with different thinning intensities from heavy thinning treatment to light thinning treatment according to
Table 2. DBH: diameter at breast height.
