Re-wetting peatlands

Export citation

Why do we carry out re-wetting?

Biogeochemical processes occurring in peat are related to the hydrological regimes, especially the depth of peat groundwater table. Draining and desiccating peatlands will enhance the oxidation of organic materials, and the emissions of carbon dioxide (CO2), the primary climate-warming greenhouse gas. Wet peatlands, which is the natural condition of peat swamp forests, may be achieved by blocking natural and man-made canals to raise the water table and therefore mitigate the cause of climate change.
