Abstract:
Aim: The goal of this chapter is to give an overview of the ecological importance of peatlands, their significant loss within the last decades, and their recent restoration and, finally, summarize our current knowledge about controls of elevated nutrient and carbon mobilization upon rewetting and how these side effects can be moderated.
Main concepts covered: In the natural state, riparian peatlands serve important functions as sinks for nutrients and hydrological buffers for downstream systems, which has earned them the name “kidneys” of post-glacial landscapes. Upon rewetting, long-term drained and agriculturally used peatlands can turn into shallow lakes, characterized by high nutrient and methane emissions and by slow development towards peat-forming vegetation in the decades to come.
Main methods covered: Comprehensive laboratory and field research for more than 30 years has improved the understanding of the biogeochemical processes controlling the nutrient cycling in rewetted peatlands.
Conclusion/Outlook: Without any further management, the recovery of peatlands might exceed a human lifetime. Different scientific disciplines must be integrated by wetland stakeholders and cross-sectoral government agencies at all stages of wetland restoration, i.e., from objective setting to post-restoration monitoring, to optimize restoration measures.
