This article examines fluctuation asymmetry as an indicator of environmental stress in woody plants growing in an urban environment. The objects of the study are several types common within the city. The degree of fluctuation asymmetry was assessed based on the morphological characteristics of the leaves, the symmetry of which may be disrupted by adverse environmental factors. The article also provides a brief botanical description of the leaves of these species. The standard deviation and coefficient of variation are calculated for each type. Based on this, relevant conclusions were drawn and an assessment of the quality of the environment was given. The data obtained allow us to judge the influence of the urbanized environment on the morphological stability of the studied species. The results can be used in monitoring the state of urban ecosystems and selecting stress-resistant species for landscaping.
