Drainage of organic soils is associated with increasing soil carbon (C) efflux, which is typically linked to losses in soil C stock. In previous studies, drained organic forest soils have been reported as both C sinks and sources depending on, e.g., soil nutrient and moisture regime. However, most of the earlier research was done in boreal region,...

Clear-felling, a predominant method for forest regeneration in areas with wet soils, has profound implications for greenhouse gas (GHG) emissions. This technique, by removing the forest cover, exposes the soil to increased sunlight, which can raise soil temperatures and enhance decomposition rates. Consequently, this process can significantly boost...
