Experience in the Use of Russian Soil Classification and Diagnosis in the Systematics of Peat Soils of Oligotrophic Bogs in the North Taiga Subzone of West Siberia

Development history and composition of peatland in the Numto natural park in Western Siberia, Russia

“…In total, bogs occupy 63% of the park's area [5]. In addition, the territory of the park is one of the southernmost regions of West Siberia, in which permafrost deposits, mainly peatlands, are widespread [6]. A boundary between the zones of flat frost mound bogs and oligotrophic unfrozen sphagnum peat bogs runs practically across the middle of the 1093 (2022) 012010 IOP Publishing doi:10.1088/1755-1315/1093/1/012010 2 Numto Natural Park [7].…”

“…The watershed area is covered with natural or insignificantly disturbed vegetation such as dwarf birchdwarf shrublichen sphagnum moss bogs, sedge-moss swamps and forests with a predominance of Pinus sylvestris. Strata that were rather heterogeneous in lithological composition (from clay to sand) serve as a mineral bed for peat bog [6].…”

“…Such landscape type generally prevails between latitudes 63-68° N in Western Siberia and has a total area of 426 thousand km 2 [9]. Both typically boreal bog ecosystems and tundra types of palsa bogs are represented [6]. The study site is located at a distance of 1.2 km to the south of the village of Numto and has coordinates of 63°30'06" N, 71°22'14" E (figure 1).…”
