The utilization of mires and some recent research results carried out in Soviet Karelia (ASSR), USSR are discussed. There are 3.5 million ha of peatlands and 1.7 million ha of paludified forests. Some 78 000 ha of drained peatlands are used for cultivation of forage and vegetable crops and there are plans to increase this amount. Some 38 000 ha of virgin peatlands have been preserved for berry production (Vaccinium oxycoc-cos, Rubus chamaemorus). The cultivation of cranberry has also been studied. Karelian peatlands are also used as resources of medicinally important plants: e.g. Me-nyanthes trifoliata, Ledum palustre, Potentilla palustris, Droseraspp., Vaccinium vitis-idaea.
Key words: peatland utilization, agriculture, berry production, medical plants, Soviet Union.

Tekijä
Minnesota's peatland resources are described, and their historical, current, and prospective uses are reviewed. Minnesota has a large peat resource that has not been intensively utilized. The state government actively encourages both the industrial development of peatlands and the preservation of significant natural peatlands. Future peatland utilization in Minnesota will probably not be monopolized by a single use, for example, traditional fuel peat production.
Key words: Minnesota, peatland utilization, peat utilization.

Peatlands complexes, site type classification and utilization of peatlands in northeast China are reviewed. The number of mire plant species common to both Finland and northeast China is about 120. Peatlands have been reclaimed for agriculture for a long time, but amelioration for forestry is only in the beginning. However, the potential of peatlands for forestry after drainage is considered high.
Keywords: China, peatland complexes, peatland site types, peatland utilization.
