“…The best result of wood properties in fresh ramen (forest site type С2) was observed in a variation with a plantation density of 10000 trees/ha, according to other authors [48] who carried out research in the Moscow region. The findings of our previous research revealed that 2500-3000 trees/ha is the optimum initial stand density in the dry coniferous forest of the Mari El Republic [15,26,44]. Also, according to [49], the wood density in pine plantations located in the northern and southern subzones of the taiga ranged from 520 to 540 kg⋅m -3 .…”

“…Research literature contains extensive discussion on the issue of stand density optimisation, which is utterly important from a practical standpoint [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The multifaceted nature of the problem and a wide range of possible solutions account for why it has not lost its relevance [15][16][17][18][19][20][21][22][23][24][25][26][27].…”

The issue of optimising the initial stand density (ISD) of tree plantations has high practical importance. The objective of this study was to nondestructively evaluate the influence of the initial stand density of Scots pine plantations located in the European part of the Russian Federation on wood basic density (BD), moisture content (MC), ultrasound velocity (UV), latewood content, and drilling resistance (DR). 45-year-old trees with stand densities of 500, 1000, 3000, 5000, and 10000 trees/ha were tested by a 5-cm-long core sample for gravimetric MCGM and BD, by PULSAR-2.2 for UV along the height (UVH) and through the tree trunk diameter (UVD), by the IML-RESI PD-400 tool for DR, and by GANN HT 85T for MC based on the electrical resistance method (MCERM). A significant influence of ISD was found on DBH, UVD, MCGM, and MCERM. ISD had no significant impact on BD, UVH, and DR. The wood BD ranged from 356 to 578 kg/m-3, with a mean value of 434±3.3 kg/m-3, and was restricted by the soil and environmental factors. DBH and 70% MCERM were good indicators of tree vitality. Linear correlations between DBH and MCERM (R2=0.67), DBH and MCGM (R2=0.74), DR and BD (R2=0.71), and the two-factor model MCGM=f(DBH, BD), (R2=0.76) were found.

“…2. The scientific and technical literature does not reflect provisions related to the spatial location and parameters of the components of plantations [4,5,6,7,20]. Despite the need to carry out cleaning cutting, many works devoted to solving this issue do not provide methods for calculating the predictive characteristics of the forest stand left for growing [1,2,3,8,16,17].…”

“…Despite the need to carry out cleaning cutting, many works devoted to solving this issue do not provide methods for calculating the predictive characteristics of the forest stand left for growing [1,2,3,8,16,17]. Also not reflected in scientific works are technological schemes for the development of apiaries during cleaning cutting with machines, which would ensure damage-free felling for the tree stand left for growing with two-row placement of trees in each strip along the edges of wide row spacings [7]. The absence of the materials listed above confirms the need to consider the designated research topic and its relevance.…”

The article discusses the issues of logging in forest areas after artificial reforestation with a double-row arrangement of forest plantations. A critical review of existing methods for carrying out selective and clear cuttings of forests was carried out. The purpose of the study is to develop a method for felling trees with a double-row arrangement of growing trees, allowing felling without damaging neighboring trees and trees in nearby rows. As a result of the research, a modernization of the forestry tractor was proposed.

A critical analysis of scientific publications devoted to the schemes and parameters of placement (planting) on the territory of the plantation of planting material is presented. The analysis of the dimensions of the machines and their working bodies in comparison with the options for planting plantation plantings is presented. Possible systems of machines for selective logging on forest plantations are recommended, which ensure felling of trees without damage to the stand left for re-growth. A scheme for growing and harvesting timber on plantations has been developed and justified. The main parameter that affects the effective growth of crops is the density of the stand. Its regulation is directed to the proposed options for thinning. The main parameters that should be taken into account when predicting the characteristics of the stand left for rearing are presented. Requirements for the technology of logging on plantations have been developed to minimize the damage to the individuals left for rearing. Recommendations on the selection of species for growing on the plantation, as well as machine systems for cutting operations, taking into account the geometric parameters of stands for different periods of logging, are proposed. Recommendations are given on the technological schemes for the development of apiaries during logging under specified conditions with the achievement of the goals set by the recommended machine systems.
