Abstract. Restoration of drained and extracted peatlands can potentially return them to carbon dioxide (CO2) sinks, thus acting as significant climate change mitigation. However, whether the restored sites will remain sinks or switch sources with a changing is unknown. Therefore, we adapted CoupModel simulate ecosystem CO2 fluxes associated influencing factors bog. The study site was peatland in eastern Canada that for 8 years left 20 before restoration. model outputs were first evaluated against 3 (representing 14–16 post-restoration) eddy covariance measurements net exchange (NEE), surface energy fluxes, soil temperature profiles, water table depth data. A sensitivity analysis conducted evaluate response simulated thickness newly grown mosses. validated then used assess changes forcing. reproduced measured showed high agreement observed temperature, depth, NEE varied slightly when mosses acrotelm from 0.2 0.4 m but significantly less uptake 1 thickness. -95±19gCm-2yr-1 over evaluation -101±64gCm-2yr-1, ranging −219 +54gCm-2yr-1, extended 28-year After 14 restoration, has mean rate similar pristine much larger interannual variability, dry years, back temporary source. predicts moderate reduction still reasonable sink under future conditions if ecologically hydrologically restored. ability dynamics its thermo-hydro-drivers important implications emission accounting climate-smart management peatlands.
