The long-term study of microbiota of oil polluted tundra peat-gleyic soils showed that oil hydrocarbons stimulate development of soil fungi in low concentrations, while soils with high oil contamination are characterized with low biodiversity of fungal complexes and decrease of their amount. After oil pollution species of micromycetes typical for more southern regions appear in the microbial soil complexes. Oil pollution drives to accumulation of hazardous and potentially pathogenic fungi in the soil, such as Aspergillus fumigatus, Fusarium moniliforme, Paecilomyces variotii. Effective remediation of soils takes place in the rhizosphere of ragwort (Thephroseris palustris), where the level of oil hydrocarbons decreases from 30% to 1,4%. This makes the plant effective to be used in phytoremediation of oil polluted soils in the conditions of northern tundra
