Short summary
Soil methane (CH4) fluxes are highly variable across natural landscapes, yet research on the variability of fluxes in unsaturated soils has not been as prevalent as in saturated portions of the landscape. In this study we measured CH4 fluxes and environmental variables across a small mountainous watershed in central Montana. We found that CH4 consumption in upland soils increased as the watershed became more dry and that a combination of terrain metrics can represent 47 % of the variability.
