Forestry is considered as a part of the forestry sector, in which the leading position is occupied by logging and processing production. Currently, the forestry sector is not the priority and is financed by residual principle. Such situation was justified in post-war years of restoration of the country from ruins and in the years of its industrialization. Now ecological improvement of the country in which the leading role must belong to silvicultural production directed on the increase of efficiency of the wood including at the expense of reasonable ways of re-forestation on the cut-down squares is required. The case in point is actual not only as a result of reduction of forest areas and reserves of wood, but also as a result of the problems not connected with wood production. The decrease in collateral uses, the deterioration of water preserving, improving, esthetic and other useful functions of the wood concerns them. In modern conditions the increase of efficiency of the main component of the wood is a forest stand inseparably linked with biological, ecological, complex efficiency. The researches of potential opportunities of prospects of subgrowth of fir-tree young growth in the conditions of the South taiga forest region of taiga zone of the center of East European Plain to the cutting and later after the cutting show 13 years the best competitiveness and viability of subgrowth in models No. 2, 5, 15-16, 18-21 characterized by the greatest height and average gain. The assessment of the younger gen-eration of the wood on differentiated scale with the determination of coefficient of quality of subgrowth confirms the received results. The determination of balance efficiency of young growths of a fir-tree European (Picea abies L.) on the squares passed by continuous cutting with preservation of sub-growth show the possibility of formation of produc-tive fir-tree plantings of natural origin from the kept subgrowth which are not conceding to forest cul-tures.
