Assessing the relative condition of the forests life of silver birch (Betula pendula Roth.) and balsam poplar (Populus balsamifera L.) in industrial and resedential areas industrial center of Sterlitamak

Determination of relative life condition of tree plantations allows to evaluate the suitability of certain trees and plants to the effects of technogenic environmental factors. Plantations of drooping birch and balsam poplar in the industrial and residential areas of Sterlitamak industrial center are investigated. At collection and processing of factual material conventional methods of study of tree plantations are used. Instrumental (diameter, height, age) and visual determination (crown density, degree of leaf damage, presence of dead branches) of diagnostic parameters are carried out. An assessment of relative life condition is carried out.
