In this paper we consider plant (geobotanical) indicators of soils, occurring in regressive bogs in the north taiga subzone of West Siberia. The specificity of regressive bogs is the difference between current vegetation and botanical composition of the peat surface horizon, which complicates their biological diagnostics. The data on peat botanical composition, degree of decomposition and thickness are presented. Destructive oligotrophic peat soils, the allocation of which is provided in the actual Russian soil classification at the level of subtype, occur in palsa bogs under shrub-lichen vegetation. Their indicators include lichens: Cladonia stellaris, C. rangiferina, C. stygia, C. arbuscula, C. mitis, Alectoria ochroleuca, Сetraria islandica, C. laevigata, Flavocetraria cucullata, F. nivalis, Govardia nigricans. A new subtype - peat oligotrophic regressive soils - which occurs in non-freezing bog is suggested. The indicators of this soil subtype in pine-shrub-sphagnum bogs are lichens Cladonia cenotea, C. chlorophaea, C. coniocraea, C. cornuta, C. crispata, C. deformis, C. gracilis, C. fimbriata, C. mitis, C. ochrochlora, C. pleurota, C. polydactyla, C. pyxidata, C. rangiferina, C. stellaris, C. subulata, C. sulphurina and liverwort Mylia anomala . The indicators of regressive soils in bog hollows are mainly liverwort Cladopodiella fluitans , mosses Warnstorfia fluitans , W. exannulata , and lichen Cetrariella delisei .

Collection of Discomycetes from two ombrotrophic bogs near Khanty-Mansiysk (boreal zone of West Siberia) was made by direct observation method. 80 specimens were identified and 51 taxa from four orders (Helotiales, Rhytismatales, Pezizales and Ostropales) revealed. Checklist with annotations presents data about occupied substrates, types of plant communities, macro and micro morphological descriptions and comparisons of ecology of species with reports from literature. This group was poorly known in ombrotrophic bogs and supplements our knowledge about the structure of fungal community of peatlands.

A digital version of the soil map of the Russian Federation, scale 1 : 2.5 M, is being prepared based on the analysis of the attributes of polygons with peat soils in the West-Siberian taiga and sub-taiga zones. The correction was perfomed in 795 polygons (with the total area of 179 483 km2) out of 1 711 polygons considered (with the total area of 262 204 km2). The currently formulated idea of the dominance of oligotrophic bogs in the West Siberian taiga region of mires served as the basis for suggestion to replace the mesotrophic peat soils by oligotrophic ones in 598 polygons of the total area of 87 250 km2. Similarly, the polygons of microcatenas comprising oligotrophic and mesotrophic peat soils (57 polygons, total area of 38 405 km2) were modified: only oligotrophic peat soils were considered to be the dominant ones there. At the same time, a number of polygons with prevailing oligotrophic soils, confined mainly to the sub-taiga zone were proposed to be replaced by polygons with mesotrophic peat soils. The thermokarst pools in ridge-hollow mire complexes that were shown on the soil map of Russia beyond the permafrost zone were eliminated from the map database; the mapping of destructive peat soils was rearranged in accordance with the new interpretation of this taxon in the Russian soil classification. This work should improve the quality of research in the field of assessing the resource potential of peat soils in West Siberia.

Remediation of oil-polluted peat soils is very important for Western Siberia. The necessary condition for successful of it is taking into consideration of ecological, climatic and hydrological condition of this region. The general parameters of environments here are high flooding, regime of temperature, short vegetation period, and specific properties of peat.
