Summary:
SUMMARY The C-sink function of peatlands is mainly controlled by soil waterlogging and Sphagnum moss dominance. La Guette peatland (Sologne, France) was drained for decades by a road ditch resulting in vascular plant (Molinia caerulea) invasion. Hydrological restoration was undertaken in 2014 and vegetation experiments were set up. In both downstream and upstream stations, three treatments (n=4) were conducted: ―control‖ with intact vegetation, ―bare peat―, and ―Sphagnum‖ (bare peat seeded with Sphagnum). Our aim was to assess the effect of such actions on plant community diversity and CO2/CH4 fluxes. In each plot, gas fluxes and plant cover were measured. 18…
