A Topographic Gradient Drives Spatial Variability of Stem CH4 Fluxes in a Temperate Alder Stand Open
Tree stems in both wetland and upland forests are a potentially significant source of the greenhouse gas methane (CH 4 ). Stem CH 4 emissions are assumed to play an important role on a global scale. Yet, uncertainties regarding temporal an…

Automatic Vegetation Mapping in Peatlands Using Drone Imagery and Ecologically Informed Machine Learning Open
Drained peatlands emit vast amounts of greenhouse gases (GHGs), contributing around 4 % of global GHG emissions. Rewetting peatlands, thus, has the potential to lower global emissions significantly. Restoring drained peatlands to prot…

Rewetting effects on nitrogen cycling and nutrient export from coastal peatlands to the Baltic Sea Open
Coastal nutrient loads from point sources such as rivers are mostly well-monitored. This is not the case for diffuse nutrient inputs from coastal catchments unconnected to rivers, despite the potential for high inputs due to intensive land…

Plant roots but not hydrology control microbiome composition and methane flux in temperate fen mesocosms Open
The rewetting of formerly drained peatlands can help to counteract climate change through the reduction of CO2 emissions. However, this can lead to resuming CH4 emissions due to changes in the microbiome, favoring CH4-producing archaea. Ho…

Active afforestation of drained peatlands is not a viable option under the EU Nature Restoration Law Open
The EU Nature Restoration Law (NRL) is critical for the restoration of degraded ecosystems and active afforestation of degraded peatlands has been suggested as a restoration measure under the NRL. Here, we discuss the current state of scie…

Salinity influence on plant traits and photosynthesis in selected peatland macrophytes Open
Coastal peatlands, despite their ecological importance are at risk from a range of disturbances that render this habitat vulnerable, affecting their productivity and could potentially trigger ecosystem shift. Salinity is one of the factors…

Full-cycle greenhouse gas balance of a Sphagnum paludiculture site on formerbog grassland in Germany Open
The cultivation of peat mosses on rewetted peatlands (= Sphagnum paludiculture) is a promising alternative to drainage-based land use, as the production function is maintained while greenhouse gas (GHG) emissions are reduced. However, to d…

Brackish water rewetting of a temperate coastal peatland: Effects on biogeochemistry, microorganisms and greenhouse gas emissions Open
Around 4 % of global greenhouse gas (GHG) emissions originate from drained peatlands. Unlike rewetting drained peatlands with freshwater, brackish water rewetting of coastal peatlands might not only reduce CO2 emissions, but also keep meth…

Modelling greenhouse gas balances of bogs in Germany based on vegetation types and water levels Open
An important share of the greenhouse gas (GHG) emissions of many European and South-East Asian countries is originating from degraded peatlands. However, only the GHG balances of a few sites can be measured directly, as these measurements …

Accelerating raised-bog restoration in a nutrient-rich environment through moss transfer – OptiMuM – a new project to improve restoration practice in Germany Open
Raised bogs are among the most threatened habitats in Northern Germany. Drainage-based land use has caused a shift to grassland vegetation on more than half of former raised bogs. In addition, high greenhouse gas (GHG) emissions from these…

Upscaling Wetland Methane Emissions From the FLUXNET‐CH4 Eddy Covariance Network (UpCH4 v1.0): Model Development, Network Assessment, and Budget Comparison Open
Wetlands are responsible for 20%–31% of global methane (CH 4 ) emissions and account for a large source of uncertainty in the global CH 4 budget. Data‐driven upscaling of CH 4 fluxes from eddy covariance measurements can provide new and in…

Active afforestation of drained peatlands is not a viable option under the EU Nature Restoration Law Open
Several EU Member States argue that active afforestation of degraded peatlands should be recognized as a restoration measure under the Nature Restoration Law (NRL). In this perspective paper, we discuss the scientific evidence on the green…

Hot or not – How do we want to rate the climate effects of peatland rewetting? Open
The climate effect accomplished through peatland rewetting is primarily assessed via the global warming potential (GWP), as it evolves from the emissions of greenhouse gases CO2 and CH4. The GWP aggregates the various radiative efficiencie…

Changes of greenhouse gas fluxes and corresponding microbial communities upon rewetting of a coastal peatland with brackish seawater Open
Rewetting of drained peatlands reduces the emissions of carbon dioxide (CO2) and nitrous oxide (N2O) substantially. However, elevated methane (CH4) emissions can occur, at least in the short-term. The impact of rewetting coastal peatlands …
