Effects of birch encroachment, water table and vegetation on methane emissions from peatland microforms in a rewetted bog.

ABSTRACT: This study investigated the influence of vegetation and microforms on methane (CH₄) balances of a rewetted bog in north-west Germany. The two study sites are in close proximity on the same former peat extraction area, one dominated by Sphagnum-mosses and the other one by a dense Betula pubescens stand with a high Eriophorum vaginatum cover. The contribution of microforms (hummocks/hollows) to CH₄ emissions and the effect of Betula encroachment has been studied. Transparent and opaque chambers were used to measure CH₄ fluxes every 3-4 weeks during daytime for one year. For the estimation of annual balances, three methods were compared and the method using water level and soil temperature as explanatory variables was selected. Fluxes were scaled to the site l
