Many peatlands have been drained and harvested for peat mining, agriculture, and other purposes, which has turned them from carbon (C) sinks into C emitters. Rewetting of disturbed peatlands facilitates their ecological recovery and may help them revert to carbon dioxide (CO2) sinks. However, rewetting may also cause substantial emissions of the more potent greenhouse… More

Rewetting can promote the ecological recovery of disturbed peatland ecosystems and may help to revert these ecosystems to carbon dioxide (CO2) sinks. However, rewetting of disturbed peatlands can also cause substantial emissions of methane (CH4) and possibly nitrous oxide (N2O). This study quantified summertime emissions of the three major long-lived greenhouse gases (GHGs) CO2, CH4… More
