Draining peatlands for forestry can change the environment and affect greenhouse gas emissions. A study in Finland found that a drained peatland forest actually acts as a carbon sink, absorbing more carbon dioxide than it releases. The researchers used advanced methods to measure carbon dioxide, methane, and nitrous oxide fluxes over 16 months. Despite drainage, the forest accumulated carbon in the soil at a higher rate than natural peatlands. This suggests that forestry-drainage can enhance the carbon uptake of nutrient-poor peatland ecosystems.
