[ID: 339] ICOS

PI: Mats Nilsson

ICOS RI is a European research infrastructure, formed in 2008, with the aim to provide accessible, high-quality data to improve our understanding of greenhouse gas sinks and emissions and to contribute to measures aimed at limiting the climate impact. -- ICOS Sweden is the national contribution to the joint European effort. It operates a network of seven field stations and one station on board a commercial vessel in the Baltic sea, performing continuous measurements of carbon fluxes as well as other related variables. The mix of stations consists of six Ecosystem stations, three Atmosphere stations and two Ocean stations. SLU together with Lund University are the two largest participating universities in ICOS Sweden. Other participants are the University of Gothenburg, Uppsala University, the Polar Research Secretariat and SMHI. All stations in the national networks across Europe follow the same standardized protocols for data gathering. The measurement data are sent to central ICOS facilities where they are quality controlled and processed before being forwarded to the ICOS Carbon portal and made available to users. SLU contributes with three measuring stations within Vindelns Försöksparker. Two Ecosystem stations and one Atmosphere station. In the coniferous forest at Svartberget an Atmosphere station and an Ecosystem station are located since 2011. An Ecosystem station is also located on the mire at Degerö since 2013 . The Atmosphere station measures the amount of greenhouse gases in the atmosphere at different levels up to a height of 150 meters. The purpose of the ecosystem stations is to understand how the uptake and release of greenhouse gases, primarily carbon dioxide and methane, is affected by climate change and to understand whether the changes cause northern forests and mires to increase or counteract the greenhouse effect. At the Degerö station continuous measurements of the biosphere-atmosphere exchange of CO2 by eddy covariance started already 2001, before becoming an ICOS Ecosystem station. The site on Svartberget hosts a Class 2 combined ecosystem and Class 1 atmospheric station.

[ID: 314] The influence of forest management on insect diversity

PI: Adam Ekholm

Theory suggests that forest managed with selection systems should hold a more diverse community of insects and thereby also be less vulnerable to pest outbreaks, and in this project we will study the effect of forest management on insect diversity. We intend to place malaise and window traps in nine uneven-aged Picea abies stands that have been randomly subjected to one of three treatments.

[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. More detailed information about the experiment: Rytter, L. and Lundmark, T. 2010 Trädslagsförsök med inriktning på biomassaproduktion [Tree species trial with emphasis on biomass production].
