This study focuses on the results of attendance of changes in the vegetation structure of the fallow after plowing, grass mixture’s sowing and measures to root away Heracleum sosnowskyi Manden. over two growing seasons (2021–2022). The work was carried out on the territory of the scientific and experimental station Otradnoye (Leningrad Region) on a three-year fallow and it revealed the formation of a grass-forb meadow. The number of plant species in each season was approximately similar (57–60) with a strong multi-year fluctuation in the occurrence of assectators. The research enables to note a significant decrease in the level of species dominance. In terms of species diversity, vegetation has maintained relative stability. There are 8 species that define 75% of species differences between the communities of the fallow of two seasons, and 2/3 of that groupe of species are cereals. Lupinus polyphyllus Lindl. make a significant contribution to the multi-year differentiation of vegetation (21%). The abundance of Sosnovsky's hogweed tends to decrease (from 2% to 1.3%). The proposed and tested methodological approach for restoration of meadow vegetation on fallows under the conditions of artificial elimination of Heracleum sosnowskyi Manden. has shown its efficiency and perspective of use., РАЗНОГОДИЧНАЯ ИЗМЕНЧИВОСТЬ ЦЕНОТИЧЕСКИХ ХАРАКТЕРИСТИК ЗАЛЕЖИ С УЧАСТИЕМ ИНВАЗИВНЫХ ВИДОВ
