Peatlands are hotspots in terms of the global carbon cycle. Depending on land use they can be long-term carbon sinks or sources. In the present study the CO2 and CH4 exchange of an afforested and drained bog forest and a natural bog-pine ecosystem were investigated by eddy-covariance measurements. Currently, the drained forest is a stronger net carbon sink, because the carbon fixation of the afforested spruces can offset carbon losses from the peat. However, this balance is very sensitive towards changing environmental forcing, whereas the natural ecosystem emerged as a small but robust and stable carbon sink.
