From another scientist I received the following explanation: “In fact, a lot of CO2 is bound in the peat that is formed in the moors. Drainage of moors (e.g. to harvest crops - potting soil!) is also a disaster for this reason. The other is that there are many highly specialized animal and plant species in bogs that can no longer live in drained bogs. On the one hand, peatlands are still peated in Germany on the basis of 99-year mining rights (how bizarre is that ?!), but one also tries to bring peatlands back to life. That is only possible with water. So: 1. Close drainage ditches, 2. remove woody plants that have grown in the bog (because a lot of water evaporates) and 3. replace coniferous forest with deciduous forest in the area around the bogs. Because more water seeps away under deciduous trees than under conifers, and this may benefit the moors as groundwater or stratified water. It is only now a huge effort to heal the mistakes of the past.”
