Abstract

A selective thinning was applied eight years after development of a poplar clone B- 229 (Populus deltoides Bartr. ex Marsh.) stand established on fluvisol, var. double-layer with fossil soil on loess-alluvium of the Sava river, with the planting distance of 5×5 m, i.e. 400 trees·ha-1. Within the square distribution of trees the phenotipically distinct trees were separated into a number defining an average distance between the trees of 7×7 m, i.e. 204 trees·ha-1, and their most significant competitors were removed. Non-perspective trees were also removed. By application of low thinning technique some 169 trees per hectare were removed (45.3%), basal area was reduced by 6.56 m2·ha-1 (37.2%), and the volume by 57.27 m3·ha-1 (36.3%). Significant separation of the group of assigned trees, and the group of the remaining trees according to the elements of tree and stand growth, as well as the height and diameter structures revealed that the thinning significantly differed from the schematic diagram of typical thinning. The value of the potential assortment structure of allowable cut in the thinning of 18.52 m3·ha-1 logs intended for cutting, class II, and 26.53 m3·ha-1 of cellulose wood provided positive balance in comparsion to the direct felling costs, and transport of the allowable cut in the thinning, and higher dense (5×5 m) afforestation costs compared to the planting distance of 7×7 m, indicating that the thinning was justified from the economic aspects.
