Short summary
This study investigates the carbon balance of a drained unmanaged peatland in Iceland. By measuring greenhouse gases for two years using eddy covariance system, it was found that this site releases less carbon dioxide than currently estimated by international guidelines. Despite a very warm year, increased plant growth balanced out higher soil emissions, keeping the total carbon loss stable. This study shows that winter emissions are crucial and year-round monitoring is vital for accuracy.
