Remnant mires back to real mires
Edgar Karolfeld, based on the experience of Canada, gives advice to peat producers of how to turn an exploited mire back into a real mire comunity. A remnant mire is a mire formed after draining the mire and the removal of peat. The leftover peat is emitted into air as carbon dioxide and methane, the main greenhouse gases. Canada, one of the most mire-rich countries in the world, sets good examples of how to renew an exploited peat field. The main idea lies in providing plant material for the mire, and covering these plants with straws. Drainage ditches have to be closed as well. If these steps are followed, it will take 5-6 years for the mire to look like nothing has happened to it.
