In the course of the work, a study was conducted of urban forests in the territory of the Sovetskiy district of the city of Novosibirsk. There are 24 alien species of woody plants that are found in the forest areas of the residential zone and in the adjacent territories naturally. A significant part of the these species appeared in the forest areas as a result of the city’s landscaping activities and the landscaping of forest parks. The identified species belong to 11 families and have a different geographical origin. The largest number of species (9) belongs to the Rosaceae family, the remaining families are represented by one or two species. Such species as Ulmus pumila, Syringa josikaea, Syringa vulgaris, Amygdalus nana, Grossularia uva-crispa, Clematis recta, Cerasus fruticose, Padus virginiana, Padus maackii, Juglans mandshurica, Ribes spicatum, Acer ginnala, Quercus robur, Berberis vulgaris , Ribes rubrum have been assigned the status of colonophytes. They are capable of self-renewing in places of drift, but are not characterized by active resettlement throughout the territory. The species Grossularia uva-crispa, Ribes spicatum and Ribes rubrum were not used in urban greening and are “runaways” from horticultural culture. Several alien species (Amelanchier spicata, Rosa rugosa, Sorbaria sorbifolia, Ulmus laevis, Viburnum lantana) are classified as potentially invasive plants. Acer negundo and Malus baccata, which are related to invasive species in Siberia and in Novosibirsk Oblast, are the most actively regenerating in the city forests.
