Abstract It remains uncertain whether and when rewetting of drained fen peatlands contributes to climate change mitigation by reducing carbon dioxide and methane emissions. Recolonization by emergent macrophytes is considered a key factor in this process. We present 5 years of carbon dioxide and methane emission data from a rewetted fen peatland in northeast Germany.

Abstract Integrated buffer zones (IBZs) have recently been introduced in the Northwestern Europe temperate zone to improve delivery of ecosystem services compared with the services associated with long‐established vegetated buffer zones. A common feature of all the studied IBZ sites is that tile drainage, which previously discharged directly into the streams, is now intercepted within the IBZ.

Integrated buffer zones (IBZs) represent a novel form of edge-of-field technology in Northwest Europe. Contrary to the common riparian buffer strips, IBZs collect tile drainage water from agricultural fields by combining a ditch-like pond (POND), where soil particles can settle, and a flow-through filter bed (FILTERBED) planted with Alnus glutinosa (L.), a European alder (black alder).
