Data on the spontaneous distribution (529 sites) of Impatiens glandulifera in the territory of Ukraine have been collected and studied comprehensively. I. glandulifera invades plant communities of the Phragmito-Magnocaricetea class (1 alliance), Salicetea purpureae (1 association), Alnetea glutinosae (1 association), Robinietea (2 associations), and Epilobietea angustifolii (2 associations). The species phytoindicative assessment, which considered 12 ecological factors, revealed that in its secondary distribution range I. glandulifera shows charactericstics of a stenotopic hygromesophyte, subacidophile and is a semi-eutrophic species. In the studied areas, the environmental niche of I. glandulifera is limited mainly by soil water response (Hd) and saline (Sl) regimes, and soil carbonate content.
