We assessed the soil moisture in urbanized habitats dominated by alien (invasive) for Eurasia tree species Acer negundo. We supposed that the soil water content under the dense canopy of A. negundo is increased compared with the soil water content under other tree species. Sample plots in urbanized habitats in the city of Yekaterinburg (Middle Urals, Russia) were combined into paired blocks: with the dominance of A. negundo or the dominance of other tree species. The conditions in each block were as similar as possible, except for the dominant tree species. In 2019-2021, 170 records of the soil water content of the upper 5 cm of soil, 85 records each in habitats dominated by A. negundo or other tree species, were performed. The average soil water content in habitats invaded by A. negundo (20.0 +/- 0.9%) was slightly but significantly higher than in habitats dominated by other tree species (18.1 +/- 0.8%). The differences were close during the three growing seasons. Also, the differences in soil moisture between habitats dominated by A. negundo and other tree species were stable when taking into account the peculiarities of weather conditions and the sample plots altitude. Thus, A. negundo is a transforming species with respect to the moisture regime in target habitats. The mechanisms of the environment-transforming impact of A. negundo can be associated with the features of both aboveground organ structures and the accumulation and decomposition of leaves and litter, as well as other soil processes.
