Yield dynamics of natural pine stands in the Forest Experimental Station of the Timiryazev Agricultural Academy with 1860

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.
