Short-term effects of thinning, clear-cutting and stump harvesting on methane exchange in a boreal forest [PDF]

Biogeosciences, 2014
Forest management practices can alter soil conditions, affecting the consumption and production processes that control soil methane (CH4) exchange. We studied the short-term effects of thinning, clear-cutting and stump harvesting on the CH4 exchange ...
