AB: With common concern surrounding the impact of increased atmospheric CO2 on global climate change, the role of forest management (i.e. thinning) on carbon sequestration is growing as a hotspot in the post Kyoto period. However, the combination strategies between forest management and carbon management are less established. Jack pine is one of the most important commercial and reforestation species in lake states of the United States and Canada, and the specie was reported to show stronger response to forest management like thinning. Obviously, there is an urgent need for understanding how harvesting intensity (i.e., thinning) affects C sequestration in jack pine stands. The aim of this study is to quantify and predict the biomass and carbon sequestration in thinned jack pine stands in eastern Canada. TRIPLEX is a generic hybrid model for predicting forest growth and carbon and nitrogen dynamics. The TRIPLEX-Management concept model was developed. The following carbon components were considered: above ground live biomass carbon, standing dead biomass carbon, harvested wood product carbon and soil organic carbon. Thinning was linked with LAI (Leaf Area Index), stand density and soil conditions and included in NPP and biomass production and allocation models. The model was also integrated with DBH distribution models, biomass allometric models, and wood products C models as well as the established height-diameter models. It is expected to optimize thinning regimes for carbon and forest management in order to mitigate climate change impacts.
