Abstract: The street greening is a means of improving the urban environment and is of great ecological importance. At the same time, anthropogenic stress leads to a decrease in the living condition of plantings and their resistance to adverse factors of the urban environment, including pathogens and pests. The presented study provides the vital condition analysis of woody plants growing along Karl Liebknecht Street in Yoshkar-Ola (Mari El Republic) in 2024. The object of the study was plantings on landscaping strips along the roadway. The sanitary condition was assessed according to the 5-point scale given in the Rules of Sanitary Safety in Forests (2020). The main part of the plants (87%) belongs to the second category of sanitary condition. 28 dead specimens (3%) were found, they must be removed and replaced with new plants. In general, the living condition of the studied plantings at this facility is assessed as weakened, which indicates a good environmental situation on K. Liebknecht Street. The most frequent damage to tree trunks are gnarled hollows and deadwood, various species of aphids are most widespread on the leaf apparatus. A negative fact is the forced pruning of birch trees located under power lines because it negatively affects the vital condition of plants and reduces decorative effect. Rowan plantations are severely weakened, and the condition of maples, apple trees, and lime trees is slightly better. The shrubs on the surveyed street are generally in better condition than the trees. It is necessary to carry out agrotechnical measures for the care of plantings to increase their viability. Studies of plantings condition of K. Liebknecht Street were conducted for the first time, in the future similar studies will be carried out on other streets of the city.
