Peatland unit types of lake-bog systems in the middle Priob’ie (Western Siberia)

Abstract

The new GIS technologies and availability of satellite images of high resolution all over the world could be a promising source of thematic information about the distribution of the Western Siberian bogs. At the same time for the accurate interpretation of peatland diversity on the base of satellite images detailed quality ground truth information is necessary. Following peatland unit types have been distinguished and described within the study area “Kukushkino Bog” situated 60 km to the east from Khanty-Mansiysk within the huge oligotrophic lake-bog system: 1 - pine-dwarf shrubs-sphagnum bogs (‘ryam’), 2 - pine-dwarf shrubs-sphagnum bog with small cotton-grass sphagnum hollows, 3 - dwarf shrubs-cotton grass-sphagnum bogs (‘open bog’), 4 - ombrotrophic ridge-hollow complex, 5 - ombrotrophic sphagnum lawns complex & water tracks, 6 - poor sedge (Carex rostrata)-sphagnum fens. Detailed study of peatland diversity and development of landscape-ecological classification of mire types for the territory of Western Siberia could be a good scientific base for the future investigation of peatlands and estimated of their values of carbon pool.
