Greenhouse Gas exchange data from Flanders Moss forest with associated temperature and soil water data
Soil CO2, CH4, and N2O fluxes from an afforested lowland raised peatbog in Scotland: implications for drainage and restoration
The effect of tree (lodgepole pine) planting with and without intensive drainage on soil greenhouse gas (GHG) fluxes was assessed after 45 yr at a raised peatbog in West Flanders Moss, central Scotland. Fluxes of CO2, CH4, and N2O from the soil were monitored over a 2-yr period every 2 to 4 weeks using the static opaque chamber method in a randomised experimental block trial with the following treatments: drained and planted (DP), undrained and planted (uDP), undrained and unplanted (uDuP) and for reference also from an adjoining near-pristine area of bog at East Flanders Moss (n-pris). There was a strong seasonal pattern in both CO2 and CH4 effluxes which were significantly higher in late spring and summer months because of warmer temperatures. Effluxes of N2O were low and no significant differences were observed between the treatments. Annual CH4 emissions increased with the proximity of the water table to the soil surface across treatments in the order: DP<uDP<uDuP<n-pris with mean annual effluxes over the 2-yr monitoring period of 0.15, 0.64, 7.70 and 22.63 g CH4 m-2 yr-1, respectively. For CO2, effluxes increased in the order uDP<DP<npris< uDuP, with mean annual effluxes of 1.23, 1.66, 1.82 and 2.55 kg CO2 m-2 yr-1, respectively. CO2 effluxes dominated the total net GHG emission, calculated using the global warming potential (GWP) of the three GHGs for each treatment (76–98 %), and only in the n-pris site was CH4 a substantial contribution (23 %). Based on soil effluxes only, the DP treatment had 33% higher total net emission compared with the uDP because drainage increased CO2 effluxes. Note: since the publication of our results we’ve notice that the site we call “near-pristine” may not be as pristine as our records originally showed. The data set is particularly large, so only summary data are included here. See also: S. Yamulki, R. Anderson, A. Peace, and J. I. L.

The work reported here was carried out at West Flanders Moss in a forestry drainage experiment (original planting in 1965) laid out in a randomised blocks design with drained and planted (DP); undrained and planted (uDP); and undrained and unplanted (uDuP) and from another separate bog, East Flanders Moss (EFM, Flanders Moss used to provide a “near-pristine bog” for reference (n-pris). Soil greenhouse gas fluxes of CO2, CH4 and N2O were measured using the manual static chamber method. In each plot three chambers were permanently installed and duplicate gas samples of the chamber headspace were taken at 4 equal intervals over 1 hour period and transferred into 20ml gas tight vials. The gas vials were transported back to the laboratory for simultaneous analysis of concentrations of CO2, CH4 and N2O by a gas chromatograph attached to an automatic headspace-sampler. Fluxes were calculated from the linear increase of gas concentrations inside the chamber with time. Flux measurements were conducted every two weeks in the first year between February 2008 and February 2009. In the second year, fluxes were measured monthly up to December 2009. In addition to the gas sampling, water table depth was measured during each sampling day from dipwells (one per treatment in each block) inserted to a depth of 100 cm. Water samples were taken from each dipwell during the gas flux measurements, transported back to the laboratory before analysed for dissolved organic nitrogen (DON) and dissolved organic carbon (DOC). Soil temperature and precipitations were also measured during the gas flux measurement and additional daily climatic data from a nearby area were obtained from the British Atmospheric Data Centre (BADC). At the end of the experiment, samples of the peat were taken at 0–10 cm and 10–20 cm depth from an area close to each chamber and were analysed for total C, total N, pH and bulk density. All data were subject to statistical analysis.
