This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

Syftet med dessa simuleringar är att klargöra hur olika skördeintensiteter påverkar kollagret över tiden och därmed klimatet genom varierande grader av biomassauttag. I arbetet redovisas simuleringar på fastighetsnivå som gjorts i Heureka-PlanWise för en granskog med boniteten G30. Bakgrunden till detta är den pågående klimatdebatten, där oron ökar för ett förändrat klimat, orsakat av en allt högre halt växthusgaser i atmosfären. EU har ambitionen att förändra energimixen och ge förnybara energikällor en större plats. Bland annat har EU som mål att 20 % av energiförbrukningen år 2020 ska komma från förnybara energikällor. Resultatet visar att kollagret sjunker med ett ökat uttag av biomassa.

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.
