The studies to determine the qualitative and quantitative characteristics of pathologies on trees have carried out as a part of a survey of plantations along the Big Voronezh ecological trail. These characteristics are not taken into account in the guidance documents, but in fact they define these trees as emergency ones. In addition to stem rot and dangerous trunk slope, recommended by the instructions, trees with butt hollows, cancerous tumors on the trunk, splitting of the trunk and shriveled skeletal branches were taken into account. The collected material and its analysis showed that (in case of accounting for trees with such pathologies) the number of trees classified as emergency can increase by 62%. Among additional pathologies, butt hollows take the leading position. It is indicated that there is a number of pathologies fatal for trees found in other types of plantations (in addition to these pathologies characteristic of oak stands). It is concluded that the modern technique for identifying emergency trees is not perfect, since it does not take into account a significant number of tree pathologies that increase the likelihood of tree breaking off or falling out, which definitely makes such trees extremely dangerous.
