Wood production of first-generation forest is an important factor in process of forest environment restoration. These forests should be considered as a transitional stage of forest development under conditions of a forest-free area. Tree species (larch, Douglas fir, spruce, silver fir, sycamore and beech) growth and produce were investigated in experimental plot which was established on meadow. Eight years after planting, conifers (European larch, Douglas fir and Norway spruce) representing 88% of basal area were sampled to investigate dimensions, weight and dry mass of the individuals. Larch is a dominating species in the 8-year-old plantation. This species shares 48% of total basal area. The dry-biomass amount of larch (25.8 Mg.ha-1) exceeds both Norway spruce (5.8 Mg.ha-1) and doulas fir (18.0 Mg.ha-1). It can be concluded that European larch provides merchantable fuel wood from first thinning. Conifers are generally more productive species compared to broadleaves in the juvenile-stage forest.
