[ID: 346] Nordic-Baltic workshop on GHG fluxes from managed/restored peatlands

PI: Matthias Peichl

Boreal peatlands provide an important carbon sink and play a key role in the global carbon cycle and climate system. During the past century, >10 million ha of natural peatlands have been drained in the Nordic-Baltic countries with the purpose to increase tree biomass production. Presently, extensive efforts are being undertaken by governmental agencies and forest stakeholders to restore these ecosystems towards their natural state with the aims to enhance conservation values and to reduce greenhouse gas (GHG) emissions from these areas. Despite this high interest and activity level, the empirical knowledge for evaluating the implications on the GHG balance is scarce. As a result, the climate impact of drained and restored peatland areas is currently highly uncertain. This workshop has two main goals: 1) Gather and synthesize the current knowledge on the climate impact of drained and restored peatlands within the Nordic-Baltic domain; 2) Explore the possibilities for synthesis papers and common research proposals.


[ID: 337] Long-term experimental set up for exploring global change effects on the peatland biogeochemistry.

PI: Matthias Peichl

Plot-based manipulations have been carried out since 1995 to investigate the single and interactive effects of increased nitrogen, sulfur and temperature on the peatland biogeochemistry. Since 2004, additional snow exclusion plots were established to simulate increased soil frost effects on various biogeochemical processes. Thus, this unique series of long-term manipulations addresses the consequences from several key global change issues on e.g. the greenhouse gas balance, vegetation dynamics and soil microbial communities in northern peatlands. https://www.silvaboreal.com/?p=trial&id=13707

[ID: 118] Bridging scales: Carbon and greenhouse gas budgets from the plot to regional level in boreal Sweden

PI: Matthias Peichl

The project goal is to assess and cross-validate carbon and GHG budgets from plot to regional scales in boreal Sweden using chamber measurements, eddy covariance and atmospheric transport modeling. Project period: 2019-2021
