Observations of intra-peatland variability using multiple spatially coincident remotely sensed data sources and machine learning

Dave O'Leary et al.

Summary: This paper presents a method that integrates multi-band remote sensing data to comprehensively interpret the intra-peatland variation of key restoration indicators. The study provides a framework for high spatial and temporal resolution monitoring of peatland restoration using future drone-based platforms.

Water-table-driven greenhouse gas emission estimates guide peatland restoration at national scale

Julian Koch et al.

Summary: The substantial climate change mitigation potential of restoring peatlands through rewetting and intensifying agriculture to reduce greenhouse gas (GHG) emissions is largely recognized. The green deal in Denmark aims at restoring 100 000 ha of peatlands by 2030. Recent advances established the functional relationship between hydrological regimes, i.e., water table depth (WTD), and CO(2 )and CH(4 )emissions. We lay the foundation of developing a high-resolution WTD map for Danish peatlands and derive a national GHG emission estimate for peat soils. The estimated annual GHG emissions are 2.6 MtCO(2)-eq, which is around 15 % lower than previous estimates. Alternative restoration scenarios and the prioritization of fields in the rewetting strategy significantly influence the GHG reduction potential.

Digital soil mapping of peatland using airborne radiometric data and supervised machine learning - Implication for the assessment of carbon stock

Dave O'Leary et al.

Summary: Peatlands cover a significant area of the Earth's surface and play an important role in global soil carbon stock. However, current mapping strategies and satellite data may not accurately detect peatlands with landcover. This study proposes a method using airborne geophysical surveys and machine learning to update peatland extent maps, which has implications for global carbon stock assessment and rehabilitation projects.

Rewetting global wetlands effectively reduces major greenhouse gas emissions

Junyu Zou et al.

Summary: Carbon and nitrogen losses from degraded wetlands and methane emissions from flooded wetlands are important factors contributing to greenhouse gas emissions. The study shows that greenhouse gas emissions from wetlands are lowest when the water table is near the surface. Re-wetting wetlands can significantly reduce future emissions.

Rewetting does not return drained fen peatlands to their old selves

J. Kreyling et al.

Summary: The effectiveness of rewetting drained peatlands in restoring plant communities and ecosystem functions remains unclear, with persistent differences and higher variance observed in restored sites compared to near-natural peatlands. The rewetting of drained fen peatlands results in the establishment of tall wetland plants and long-lasting differences in biodiversity, ecosystem functioning, and land cover characteristics. Understanding the outcomes of rewetting efforts is crucial for improving planning and implementation of peatland restoration.

Overriding water table control on managed peatland greenhouse gas emissions

C. D. Evans et al.

Summary: This study shows that the depth of the water table is the main factor influencing greenhouse gas fluxes in peatlands. By lowering the water table depth by 10 cm, emissions of CO2 and CH4 can be reduced by the equivalent of at least 3 tonnes of CO2 per hectare per year, until the water table depth is less than 30 cm.
