Scots pine is one of the most widespread tree species in Eurasia, which determines its confinement to different growing conditions. The origin of the planting material influences the variables of forest stands. According to the data of long-term experiments in the Forest Experimental District of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy, it was revealed that the most promising are the stands grown from seeds of local origin. Such stands are characterized by maximum wood quality, durability and productivity.

The purpose of the study is to select and justify a regression model that will most accurately reflect the dependence of heights on the diameters at breast height of pine plantations in the European part of Russia. 28 height-diameter models were selected based on literary sources and tested for research. Näslund’s equation is justified as the best model for the relationship between height and diameter at chest height. It can be applied in practice when performing forestry and research work in pine forests of the European part of Russia.

Due to the longevity of forest vegetation, the problem of its age-related changes remains the least studied and most urgent. For 150 years, the Forest Experimental Station has been an experimental testing ground for a number of generations of foresters who have created experimental facilities to solve a number of pressing problems. On the example of natural pine stands with 1860, it was shown that in an urbanized environment, the life cycle of stands is accelerated, and their durability is reduced. At the same time, under the influence of negative factors (emissions from transport, enterprises, recreational load, etc.), a decrease in yield is observed.
