Abstract

The article provides an analysis of changes in the areas of Norway maple stands in the forests of the Republic of Tatarstan from 1944 to 2019. According to the accounting data of the forest fund as of 01.01.2020, the area occupied by maple in the Republic of Tatarstan is 29.3 thousand hectares (2.5 % of the forest fund area), including 5.0 thousand hectares of young growth of the 1st and 2nd age class, 21.4 thousand hectares of middle-aged trees, 1.9 thousand hectares of ripening trees and 1.0 thousand hectares of ripe trees. A reliable relationship was revealed between a decrease in the area of maple after extremely low frosts of 1939–1940, 1941–1942 and 1978–1979, and an increase in its area after the drought of 2010. After the drought of 2010, there is a natural replacement of highly productive birch stands with low-quality maple stands, which will lead to a deterioration of the commodity structure of the felling fund of the Republic of Tatarstan. Maple plantations have a mixed composition and farming in them should be aimed at increasing the proportion of species valuable for these conditions – oak and birch.

Possessing a high ability to regenerate by seed and vegetative means, maple, by 2019, restored its share in the forest fund of the Republic of Tatarstan

Summary

Introduction

Norway maple (Acer platanoides L., 1753) is an economically valuable tree species, slightly represented on the lands of the forest fund of the Russian Federation [1,2,3]. Norway maple prefers fertile loamy, sufficiently moist, well-drained soils; grows most often in deciduous and mixed forests in the form of admixture and undergrowth, but it can dominate – 90 % of pure maple forests are concentrated in Bashkiria [2, 5]. It is most widespread in oak forests, especially in forest ravines [4]. The growth ability of maple lasts up to 40–50 years It is quite shade-tolerant, especially at a young age, second only to linden in this respect. According to the accounting data of the forest fund as of 01.01.2020, the area occupied by maple in the Republic of Tatarstan is 29.3 thousand hectares (2.5 % of the forest fund area), including 5.0 thousand hectares of young growth of the 1st and 2nd age class, 21.4 thousand hectares of middleaged trees, 1.9 thousand hectares of ripening trees and 1.0 thousand hectares of ripe trees [7]
