Terinov N.N.
The method of formation of dark-coniferous forest stands is based on carrying out of cycle of the transformation cuttings in secondary deciduous average age stands and ripening stands with the second story of dark-coniferous species and young growth of dark-coniferous ones. Term of carrying out of the first cutting depends on time of settling of dark-coniferous species on felling site or under crowns of deciduous forest stands. Last transformation cutting in a cycle of this kind of cuttings is carried out with two-stage cutting or stripe-gradual cutting. Optimum term of the beginning of their carrying out comes at 40–50-years age of spruce and fir trees.
