The Spatial Variability of Methane Emission from Grass-Moss Fens of the Subtaiga and Forest-Steppe of Western Siberia

Emission of methane from the grass-moss fens of the Western Siberia subtaiga was studied using a static chamber method. It was established that a median half of the interquartile range of the specific flow of CH4 in the studied wetland ecosystems constituted 4.9 ± 2.9 mg of CH4/(m2 x h). It was show...

Summary:Emission of methane from the grass-moss fens of the Western Siberia subtaiga was studied using a static chamber method. It was established that a median half of the interquartile range of the specific flow of CH4 in the studied wetland ecosystems constituted 4.9 ± 2.9 mg of CH4/(m2 x h). It was shown that such a high spatial variability of emission is caused mainly by the difference in the level of fen waters. It was found that, in these observations, a higher level of the water stand correlates with lower emission values. The causes of this phenomenon are discussed, and recommendations for conducting field studies for estimating the regional flow are given.
