Abstract

The paper investigates the effect of logging equipment left on the viability of growing lighter trees and young growth of spruce, as well as stem rot on the physiological state of pine, spruce and larch trees. It is found out that the use of multifunction logging machines damages the young growth. Damages seriously degrade the viability of a tree: photosynthetic rate and pigment content are reduced, water status and normal operation of the root system are broken, unproductive respiration is enhanced. Mechanical trunks and roots bark damage are the greatest physiological tree damage. The kerf of a half of a stem diameter at a depth causes death of a tree in the second year. Mechanical damages do violence to the trees growth processes. The annual ring width of large and lighter spruce trees undergrowth at the open fellings after the mechanical bark damage in the second year in the place of damage is reduced by 40 %, over the place of damage is reduced by 17 %. Harsh glare enhances the negative damage effects and causes death of a tree. Two years later 67 % of damaged trees in the open fellings dry out. In the selective loggings with shading in 4 years all trees with mechanical bark damage have maintained the vitality and high physiological activity. With the equal type of damages the “northern” spruce populations reduce the photosynthetic rate by 38 %, “southern” populations, where the climatic factors tension is higher - by 64 %. Stem rot, rising from the stump of pine, spruce and larch trees, disturbs the normal physiological and growth processes. The annual ring width of the rot-damaged pine trees over the last 10 years became narrower by 16 % (2 mm), than that of the vigorous trees (2.35 mm).
