Assessment of the status of the Bakchar bog marginal part of the Great Vasyugan Mire
The aim of the study. The aim of the study was to assess the status of the forest-mire Bakchar bog ecotone (southern taiga subzone of Western Siberia) of the Great Vasyugan mire. Location and time of the study. The key study site was located in the basin of the River Klyuch (56º58' NL, 82º36 EL...

The aim of the study was to assess the status of the forest-mire Bakchar bog ecotone (southern taiga subzone of Western Siberia) of the Great Vasyugan mire. Location and time of the study. The key study site was located in the basin of the River Klyuch (56º58' NL, 82º36 EL). The study was conducted in 2017-2018. Methodology. The georadiolocation method, field landscape studies and geoinformation modeling methods were used. Main results. The study site was dominated by the mired birch-dominated forest on peat shallow soils. The surface microtopography is strongly partitioned, with the average value of the height standard deviation of 14 and the average amplitude of height fluctuation 58.4 cm. The amplitude of the height fluctuations directly determines the habitat moisture content, which makes it advisable to use quantitative microtopography parameters for assessing hydromorphic transformation of forest-mire ecotones. The main part of the territory may be categorized as the damp-forest-meadow stage of moistening, scoring 14,2-15,7 according to the ecological scale of D.N. Tsyganov. Statistical analysis showed that habitat moisture is mainly determined by its mineral bottom gradient, and the peat deposit thickness is directly dependent on the contemporary surface gradient. As a result of peat accumulation, the surface was leveled and the average gradient decreased from 0.23° to 0.15°, thus contributing to the further hydromorphic transformation of the site. Conclusion. The comprehensive assessment of the status of the forest-mire ecotone of the Bakchar mire provided new information about ground surface transformation due to peat accumulation. Quantitative estimate of the relief role as a main factor of mire development in the area was obtained. This new information can be used as a basis to develop prognostic models of mire development and growth in the areas adjacent to them and to evaluate the role of potentially increased mire areas in the global carbon cycle.
