Differences in the vegetation cover of reclaimed areas disturbed by emergency oil spills were revealed in contrasting landscape positions. It is shown that after 10–15 years, the plant communities in poorly drained positions, in contrast to well-drained positions, are more close to the natural bog vegetation in terms of the main phytocenotic indicators and have a physiognomic similarity with it. However, significant differences in the species composition and the ratio of species still persist
