Following the removal of the old forest in winter 1986/87 on the plot with the group clear cutting and in winter 1991/92 on the plot with the shelter wood cutting, the fir is growing in all three variants in open area. The inventory carried out in 2005 revealed that, in each case, the best experimental results were obtained by the stand on the surface with the group clear cutting (3-Rg). The stands from surfaces with the clear cutting (1-Rz) and shelter wood cutting (2-Rcz) show worse results which also differ from each other. From the point of view of mean breast height diameter and height, a better situation was observed on the 1-Rz, while from the point of view of the number of trees, mean Kraft class and productivity – on surface 2-Rcz.
