The article presents the results of a survey of dangerous and emergency trees using minimally invasive methods of instrumental quality control of balsamic poplar (Populus balsamifera L.) stem wood in the industrial center of Bratsk, Irkutsk region. The taxation indicators of the trees were determined: the diameter of the trunk at a height of 1.3 m, the height of the tree, the slope of the trunk, the distance from the edge of the driveway to the plantings were measured, and a study of the sanitary condition of the trees was also conducted. The diameter of the barrel was measured using a measuring fork. A Makarov pendulum altimeter was used to determine the height of the tree. The proportion of internal damage to trunks by rot with a decrease in wood density was determined using a Resistograph 4450 device. All the surveyed trees are at a critical age of natural ripeness, when the trees begin to hurt and collapse, have rot of varying degrees of destruction, and numerous mechanical damage to the trees.
