RESULTS OF DENDROCHRONOLOGICAL STUDIES IN BIRCH STANDS AT THE DOMODEDOVO FORESTRY OF THE MOSCOW REGION

Abstract

Technology), Mytishchi, e-mail: ( Betula pendula Roth.) belongs to disseminated vascular tree species and is relatively poorly distinguishable on wood samples. This led to relatively little research of this species on Russian plain by dendrochronological methods. At the same time, in conditions of recreational forests and woodland parks of Moscow and Moscow region this specie is one of the most important forest-forming species. Dendrochronological diagnosis for features of radial growth in these conditions has a great interest for forest science theory as well as for forestry practices. The results of dendrochronological investigations in betula satnds from Domodedovo forestry of Moscow region are disclosed in this article. On the basis of the conducted studies it was established, that all model stands consist of Vi age class. The trees of all four test plots, despite the presence of differences in the phytocenoses formed with their participation in the floristic composition of the undergrowth and live ground cover, are characterized by similar conditions for the growth and development of birch trees. Dendroclimatic analysis showed that water scarcity in June and July is the main limiting factor of ecological growth, which can cause poor growth and poor condition of birch trees. in general, there are no strong and unambiguous connections between the variability of specific individual meteorological parameters and the variability of annual rings, which is typical for plantations in non-extreme conditions of vegetation. To improve the condition of plantations, to stimulate radial growth in order to accelerate the overgrowing of wounds and mechanical damage to trunks, watering trees in June and July can be recommended in those years when the amount of precipitation over these months will be significantly lower than the average
