Ecosystem carbon and water fluxes in boreal forests

PI: Matthias Peichl

This project explores the ecosystem carbon and water fluxes at the Rosinedal and Svartberget forests using the eddy covariance technique. At Rosinedal, we also investigate the effect of ecosystem-scale N addition on these fluxes. The project is part of the Wallenberg project: Branchpoints.

How does rewetting affect the greenhouse gas balance of drained peatland forests in boreal Sweden?

PI: Järvi Järveoja

The overall aim of this project is to investigate how rewetting affects the GHG balance of drained peatland forests in boreal Sweden. This will be achieved by eddy covariance measurements of the ecosystem-scale CO2 and CH4 exchanges in work package 1 (WP1), combined with estimates of spatial variability from plot-scale GHG flux measurements across replicated sites in WP2. In WP3, the separate responses of the individual net CO2 exchange component fluxes will be determined.

Understory carbon and water budgets in boreal forests measured from the below-canopy eddy covariance towers.

PI: Jinshu Jackie Chi

Boreal forest floor plays an significant role in the ecosystem-scale carbon and water dynamics in boreal forests. However, accurate quantification of understory's contribution is quite challenging due to e.g. non-ideal conditions for the below-canopy eddy covariance measurements. In my project, I will use the direct below-canopy eddy covariance towers as well as manual chamber measurements to assess the carbon and water budgets of forest floors in two contrasting boreal forests, Svartberget and Rosinedal, respectively, to provide a better understanding of the mechanisms in carbon and water cycles in boreal forest ecosystems.

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

Does sustained yield of forest biomass result in a carbon sink at the forest landscape scale?

PI: Matthias Peichl

The project goal is to estimate the full carbon balance of a managed boreal forest landscape (i.e. the Krycklan catchment) using tall tower eddy covariance measurements and bottom-up scaling based on detailed plot-level measurements of terrestrial and aquatic carbon fluxes combined with high-resolution Lidar data. Project period: 2016-2018
