Age Dynamics of Normal Gray Alder Stands in the Taiga Zone of the North-East of the European Part of Russia
Journal Title: Lesnoy Zhurnal (Russian Forestry Journal) - Year 2023, Vol 6, Issue 6
Abstract
In order to organize, plan and conduct forest management on a scientific basis in stands with predominance and participation of gray alder (Alnus incana (L.) Moench), formed in the conditions of the taiga zone, reliable data on the structure, growth and productivity of stands are needed. At present, there is an urgent need to develop growth progress tables for gray alder stands, as the areas occupied by this species have significantly increased as a result of abandoned agricultural lands overgrowth. The development of a unified system of regulatory and reference materials for accounting the number, assessment of the condition and volume of use of stands of gray alder in the European North of Russia is an important and urgent task. Growth progress tables for normal gray alder stands located in the taiga zone of the north-east of the European part of Russia have not been developed by anyone before. The purpose of this research is to study the age dynamics of normal gray alder stands to compile growth progress tables. We used 193 model trees of gray alder, as well as data from 175 sample plots. As a research result for the growth progress tables with relative stands density of 1.0 we obtained the equations for determining the average height, diameter, and stands stock by bonity classes. On the basis of the obtained equations, the tables of growth progress of normal stands by bonity classes were developed. The proposed tables will contribute to improving the accuracy of forest inventory, will give the opportunity to objectively assess the forest resources of the most represented stands, to forecast their growth when performing a set of works on the protection, conservation, and reproduction of forest resources, improving the ecological functions of the forest, as well as to control management in stands.
