The process of wood degradation is common in natural ecosystems. At the same time, the rot developing in the stem leads to a decrease in the mechanical strength of the tree, making it potentially dangerous in an urban environment. The intensity of damage and the rate of its spread along the stem can vary significantly. The aim of the study has been to assess the nature of wood degradation of Norway maple and Schwedler maple growing in the Dendrological Garden named after I.M. Stratonovich using the Arbotom impulse tomograph. The dendrological garden is located within the city limits of Arkhangelsk. A survey of taxa has been carried out using generally accepted methods. At the initial stage, the biometric characteristics of the trees have been measured and a visual assessment of their sanitary condition has been performed. Using the tomograph, measurements have been taken at various heights of the stem, which has made it possible to obtain a complete picture of the internal structure of the wood and identify possible areas of destruction that are not visible during visual inspection. The data obtained has demonstrated that Norway maple and its variety have differences in resistance to internal rot. Significant disturbances have been recorded in Norway maple samples, indicating the lower viability of this species. At the same time, Schwedler maple is characterized by greater resistance to rot damage, which may indicate its superior adaptability to local climatic conditions. Correlation analysis has shown that there is no relationship between the age of the maples and the speed of pulse propagation in the wood. The results of the study can become the basis for work on the introduction and breeding of maple species suitable for the northern region, as well as help in developing recommendations for plant care and early diagnosis of tree diseases. The use of impulse tomography not only allows the detection of existing wood damage, but also serves as a tool to prevent the spread of diseases. Developing programs for regular inspection of trees using this technology can significantly increase the effectiveness of tree protection measures.AuthorsIrina A.
