Paper doi abstract bibtex \textlessp\textgreater\textlessstrong\textgreaterAbstract.\textless/strong\textgreater Forestry practices often result in an increased export of carbon and nitrogen to downstream aquatic systems. Although these losses affect the greenhouse gas (GHG) budget of managed forests, it is unknown if they modify GHG emissions of recipient aquatic systems. To assess this question, air–water fluxes of carbon dioxide (\textlessspan class="inline-formula"\textgreaterCO$_{\textrm{2}}$\textless/span\textgreater), methane (\textlessspan class="inline-formula"\textgreaterCH$_{\textrm{4}}$\textless/span\textgreater) and nitrous oxide (\textlessspan class="inline-formula"\textgreaterN$_{\textrm{2}}$O\textless/span\textgreater) were quantified for humic lakes and their inlet streams in four boreal catchments using a before-after control-impact experiment. Two catchments were treated with forest clear-cuts followed by site preparation (18\textlessspan class="thinspace"\textgreater\textless/span\textgreater% and 44\textlessspan class="thinspace"\textgreater\textless/span\textgreater% of the catchment area). GHG fluxes and hydrological and physicochemical water characteristics were measured at multiple locations in lakes and streams at high temporal resolution throughout the summer season over a 4-year period. Both lakes and streams evaded all GHGs. The treatment did not significantly change GHG fluxes in streams or lakes within 3 years after the treatment, despite significant increases of \textlessspan class="inline-formula"\textgreaterCO$_{\textrm{2}}$\textless/span\textgreater and \textlessspan class="inline-formula"\textgreaterCH$_{\textrm{4}}$\textless/span\textgreater concentrations in hillslope groundwater. Our results highlight that GHGs leaching from forest clear-cuts may be buffered in the riparian zone–stream continuum, likely acting as effective biogeochemical processors and wind shelters to prevent additional GHG evasion via downstream inland waters. These findings are representative of low productive forests located in relatively flat landscapes where forestry practices cause only a limited initial impact on catchment hydrology and biogeochemistry.\textless/p\textgreater
