Meyer and co-workers measured greenhouse gases methane (CH4), nitrous oxide (N2O) och carbon dioxide (CO2) in a forest growing on drained, fertile peatland. The forest was barely a carbon sink and a large emission of N2O was detected. The authors conclude that forests on such land do not become net carbon sinks under a rotation period, implying that reforestation on such lands not necessarily helps the climate. Therefore the local conditions should be taken into account before reforestation. Read the whole artikel in Biogeosciences.
