mixed types of forest at the young age.

The studies conducted to identify the growth and structure of wood of experi-

1.The main inventory indices of mixed pine-larch stands, including the composition of stands, are formed in the cowberry and cowberry-mixed grass and

2.Young trees in these types of forests have an average productivity that is approximately equal to bonitet class III; mixed young trees of pine and larch

3.Experimental mixed forest crops of pine and larch with the total area of 214 hectares, established in the Irkutsk region, indicate that pine and larch by the age of 21 have good growth and development. At the same time larch is higher

4.The closure in the rows is high; in general, per 1 hectare the stand density is 0.77 which means that in the rows the density is more than 1.0. In these forest crops, thinning is required to provide additional opportunities for growth and development of forest crops [12, 13]. It is recommended to expand the creation of mixed pine-larch and larch-pine forest crops both by sowing and

5.In forest cultures, slender full-wood trees are formed with good physical and mechanical properties of wood. Thinning young plants (a sufficiently high degree of thinning 35–50%) can achieve more uniform placement of trees in rows, which will increase diameter and height, reduce the severity of intraand interspecific competition, and increase the productivity of experimental forest crops. It is also recommended to practice creating mixed forest crops of pine and larch by sowing or planting in appropriate forest-growing conditions, thereby preserving larch as the predominant tree species of Russian forests and increasing the biological diversity of light taiga forests in Eastern

6.The prospects for further development of research should be seen in a further study of the growth and development of light-coniferous mixed stands in the Irkutsk region of the Angara region in the design and construction of a mathematical model for the dynamics of light-coniferous taiga plantations with the aim of increasing their biological stability and productivity, as well as improvement of the quality of the trunk and tree canopy and physicomechanical properties of wood of pine and larch, silvicultural measures in particular to optimize the quantity of sowing and planting, and commercial thinning in young stands improving the composition and quality characteristics of pine
