Theme X. Peatland carbon budgets and greenhouse gas (GHG) fluxes
We estimated the current greenhouse gas balance (in CO2 equivalents, CDE) for 68 forestry-drained sites in Finland, ranging from hemiboreal to north boreal vegetation zones and from fertile to poor sites. We found net emissions from soil at fertile but not at poor sites. The role of CH4 and N2O emissions was minor. The large CO2 sinks of the growing tree stands caused the ecosystem balances to be clearly positive (sink) even at fertile sites.
