Comment on "Soil CO2, CH4 and N2O fluxes from an afforested lowland raised peat bog in Scotland: implications for drainage and restoration" by Yamulki et al. (2013)

[摘要] Yamulki and co-authors address in their recent publication the importantissue of net emissions of greenhouse gases (GHGs) from peatlands where landuse conversion has taken place. In their case, they studied conversion toforestry versus peatland restoration after a first rotation of plantationforestry. They monitored soil-derived fluxes of carbon dioxide (CO₂),methane (CH₄) and nitrous oxide (N₂O) using opaque chambermeasurements on planted and unplanted control treatments (with or withoutdrainage), and an unplanted plot within a restored (felled) block on formerlowland raised bog. They propose that their measurements of greenhouse gas(GHG) emissions at these sites suggest that the total net GHG emissions, in100 yr carbon dioxide equivalents, of the restored peat bog would be higherthan that of the peat bog with trees. We believe there are a number of issueswith the measurement, calculation and comparison of these greenhouse budgetsthat may invalidate this conclusion.
