The influence of selective thinning on the social structure of the young scots pine stand
The growth of the pine stands subjected to different thinning regimes was investigated on 3 permanent experimental plots established in the years 1967–70 in the central and northeastern Poland in the random block design. The results of the three treatments different in thinning intensity (light, moderate and strong) were compared to the control (without thinning). The analysis showed that light thinning (removal of 10% of stand basal area) did not have significant influence on stand social structure. The minimal thinning intensity required to obtain selective effect was about 20–30%.
