Small water bodies including drainage ditches can be hotspots for methane (CH4) emissions from peatlands. We assessed the CH4 of a drained and rewetted temperate fen managed unmanaged over course 2.5 years, covering three vegetation periods. Ditch in were significantly higher than fen. In contributed up to 91% annual budget, despite only 1.5% area. solely made ditch emissions. When uptake by pe...
