Abstract: FIELD: forestry. SUBSTANCE: depending on determined level of value of low-value plantations, their silviculture characteristic, stability and other conditions, reconstruction is carried out by sections which are determined according to size of area and other parameters with application of four major methods with corresponding type of reconstruction: full one-stage; full 2-3-stage; partial one-stage; partial 2-3-stage. In this case, partial and also full 2-3-stage reconstruction is effected according to natural specifics and final goals. It is made uniformly over land area, strip by strip, and width of strips depends on top height of trees, properties of tree species and particularities of plantation being reconstructed and local conditions. Large forest areas or groups of areas are reconstructed in phases by strictly defined sections so that repetition periods are corresponding to 2-3-stage reconstruction for respective renewable species. For more speedy reconstruction of large sections, number of phases is reduced to 3-5. Reconstruction sections are planted simultaneously at distance from each other equal to their two-three widths (not counting width of section being planted). EFFECT: high efficiency.
