Soil carbon fluxes after a Sweden wildfire: impacts of burn severity and forest management
Julia Kelly, Researcher at Centre for Environmental and Climate Science (CEC), will give a seminar with the aforementioned title.
In 2018, an extreme drought led to the worst wildfire season in Sweden in over a century. The Ljusdal fire, the largest area burnt that year (8995 ha), offered a rare opportunity to quantify the combined impacts of wildfire and post-fire management on Scandinavian boreal forests. I will present chamber measurements of soil CO2 and CH4 fluxes, soil microclimate and nutrient content conducted during the first growing season after the fire in Scots pine (Pinus sylvestris) forests. The results show that burn severity and stand age are key drivers of post-fire soil respiration whereas salvage-logging had no significant impact. None of these three factors had a significant influence on soil CH4 uptake. The presented short-term effects and ongoing monitoring will provide essential information for sustainable management strategies in response to the increasing risk of wildfire.
