Site Description

Test site Vasjugan is located at the south-west part of the West-Siberian Plain in the South Taiga zone with elevations from 110 to 130 m a.s.l. The studied area is drained by Chaya River and its feeders: Iksa, Bakchar, Teterenka, Andarma and Parbig rivers. Watersheds are occupied by bogs. Left-side river terraces are usually paludificated. Bog massifs formation started 4.5 – 5 thousand years ago and since that time the peat deposits cover the initial relief roughness. Watershed bogs have peat depth about 3-4 m. Underlying soils are mostly carbonate loams and clays with lake-alluvial genesis. Soils are sod-podzol and sod-gley type with relict humus horizons, remained from intense humus accumulation epoch in the Holocene climatic optimum. The natural vegetation is very various. The large part of the area is occupied by wet of paludificated broad leaved forests (Betula pendula Roth. and Polulus tremula L.). Darkconiferous forests with herbaceous-moss layer typical for the South Taiga zone covers very small areas. Mires occupy about 50% of the West Siberia area. Mire types at the test site are presented by open sphagnum and sedge fen, ridge-hollow and ridge-lake complex, pine-shrub-sphagnum community (or “ryam”). Ryams with different tree height (Pinus sylvestris L.) and tree layer density are located at bogs periphery and in the central parts of bog massifs.
