A warming climate is instigating more frequent and severe wildfires, releasing carbon (C) stored in biomass and soil as CO2. Peatlands are globally significant sinks of C; however, peatland wildfires cause massive C loss, leading to an urgent need to determine how wildfires affect northern peatland C storage and functioning. It is unknown how different peatland types recover in terms of plant community reestablishment and C fluxes. Most research focuses on precipitation-fed bogs, while little is known about whether recovery in groundwater-fed fens is comparable, despite accounting for most peatlands in western Canada. Thus, the objectives of the study are to examine differences in different (i) C fluxes and (ii) vegetation communities 6-7 years post-fire, compared to unburned controls. A bog and fen, impacted by wildfire in 2016, were instrumented to collect data on CO2 and vegetation across a fire severity gradient. Based on preliminary results, burned sites had greater net C uptake in the understory than unburned controls, but the difference was not significant at the bog, while C uptake at the severely burned fen was significantly higher. Although biomass was reduced post-fire, rapid recovery of shrubs at the moderately burned fen resulted in greater biomass than the unburned fen, and similar biomass between the unburned and severely burned fens, which was not the case at the bog sites due to complete overstory loss. These results will contribute to understanding recovery of peatland function following disturbance and provide a baseline trajectory for ecosystem development following restoration and reclamation.
