STAGES OF REWETTING IN THE PEAT EXTRACTED AREA OF THE IVANOVSKOYE FEN PEAT DEPOSIT

The article was discussed the main stages of rewetting of the cut-away Ivanovskoye fen peat deposit based on eight years of observations. Analysis of the main parameters of groundwater levels (high, average, low annual and monthly values of groundwater levels and amplitude of fluctuations, as well as the course of the curve relative to the earth's surface), values of redox potential, total mineralization, acidity, succession of vegetation and greenhouse gas emissions (CO2-eq.) allowed us to conclude that the peatland undergoes three stages of restoration after the implementation of environmental rehabilitation measures. The measures were contributed to an increase in the average annual values of groundwater levels to the level of the earth's surface, the restoration of the species diversity of fen phytocoenoses (currently reed-sedge phytocenoses predominate) and a 2.4-fold reduction in greenhouse gas emissions.
