Growing season carbon dioxide and methane exchange at a restored peatland on the Western Boreal Plain.

Highlights: [•] We investigated greenhouse gas exchange in a restored cutover peatland in Boreal, Alberta, Canada. [•] Three year post restoration, on average restored plots were growing season sinks for carbon. [•] Plant community on site consisted largely of spontaneously recolonizing species. [•] CO2 flux will likely remain high from dry microsites. [•] Wet microsites may be growing season sinks for CO2 but will likely be large sources of CH4. [ABSTRACT FROM AUTHOR]
