%0 Research Notes %T Changes in the carbon balance of forested mires in Karelia due to drainage %A Sakovets, Vladimir %A Germanova, Natalia I. %D 1992 %J Suo - Mires and peat %V 43 %N 4-5 %U http://suo.fi/article/9715 %X The carbon balance of undrained and drained parts of a herb-rich pine fen mire ecosystem were calculated. The drainage had been carried out twenty years earlier. Drainage resulted in an increase of 1.23 t C ha-1 a-1 within the ecosystem. The increase was due to increased stand production, which exceeded a loss of carbon from the peat (-0.32 t ha-1 a-1). Keywords: Peat, peatland forestry, phytomass, Russia
