The results of long-term monitoring of microbiological activity of disturbed lands after an oil spill that occurred on the territory of the Southwestern part of Yakutia are presented. It has been established that after the introduction of biological preparations based on the native hydrocarbon-oxidizing microflora in soils, both with fresh and old oil pollution, the microbiological activity of soils intensifies. The activation period of hydrocarbon-oxidizing activity of soil microorganisms in the cryolithozone was about 7 years for fresh oil pollution and 3 years for soils with old oil pollution. Therefore, the method of activation of biological destruction of oil pollution with the use of native hydrocarbon-oxidizing microorganisms is not relevant for permafrost soils with long-term oil pollution. It is necessary to develop new ways to restore disturbed lands with long-term oil pollution.
