[ID: 479] Influence of Tree Species on Soil Carbon Cycling across Boreal Forest Ecosystems
PI: Xanthe J Walker
This research aims to assess the influence of vegetation composition, climate, and disturbance history on soil organic carbon (SOC) accumulation. We will compare the mean residence time of SOC in spruce, pine, birch, and aspen-dominated forest ecosystems located near three separate research stations in Sweden and Finland. These sites range in species present, climate, and disturbance history. We will then assess how SOC accumulation in these forests compare to our studies in boreal North America (Alaska, USA, and the Northwest Territories and Yukon Territories of Canada). Our comparative approach will enhance our current scientific understanding of the drivers of SOC accumulation with ongoing climate warming.

[ID: 196] Climate benefit from the afforestation of available agricultural land
PI: Reimo Lutter
According to the recent estimation for Northern Europe, about 1.8-2.6 M ha of agricultural land is available for afforestation and intensive biomass production (Rytter et al. 2016). However, the long-term effects of different species C sequestration potential are unknown on former agricultural land. For the basis of current project, the growth data was obtained from tree species (hybrid aspen, poplar, birch, spruce, larch and willow) experiments on five former agricultural sites along a latitudinal gradient in Sweden (56° to 64°N). Site index curves were calculated to predict the potential production for each tree species and different long-term scenarios were tested to investigate each species climate benefit potential on former agricultural lands.

[ID: 107] Comparison of ecosystem C and N stocks in Norway spruce vs. Scots pine stands throughout Sweden
PI: Robert Blasko
We are evaluating the performance of Norway spruce vs. Scots pine stands at the sites equally suitable for both species in the experiments at Kulbäcksliden 1028-1029, Flakaträsk 2458, Övra 1061, and Björkheden 1062. The aim is to evaluate how the different species productivity affects C and N stocks of he ecosystem and some of the important C fluxes; soil CO2 efflux and litterfall.

[ID: 106] Impacts of tree species identity and mixing on ecosystem C and N stocks
PI: Robert Blasko
The original aim of this experiment was to compare the growth of Scots pine vs. Norway spruce, and their mixture at a medium fertility site near Främlingshem suitable for the growth of both species. Our aim was to evaluate the effects of tree species and their mixing on ecosystem C and N stocks, as well as on some of the important C fluxes.
