SUMMARY
Boreal peatlands contribute significantly to the global carbon store and have a major role in global greenhouse gas (GHG) balances. The peatland drainage for forestry purposes has an effect on CO2, CH4 and N2O fluxes and thereby on GHG balances. In Finland, there is a remarkable area of drained peatlands, which indicates that decisions made for future peatland uses have effects on GHG emissions at a larger than national scale. Identification of reliable measures of GHG balances is needed to estimate whether suitable conditions for GHG sinks may be generated through peatland management. As extensive GHG data is expensive to acquire, alternative methods to obtain data from larger areas are needed. Statistically-based spatial models provide a cost-efficient approach for mapping and…
