| Abstract: | A physiological growth and yield model was applied for assessing the effects of forest management and climate change on the
carbon (C) stocks in a forest management unit located in Finland. The aim was to outline an appropriate management strategy
with regard to C stock in the ecosystem (C in trees and C in soil) and C in harvested timber. Simulations covered 100 years
using three climate scenarios (current climate, ECHAM4 and HadCM2), five thinning regimes (based on current forest management
recommendations for Finland) and one unthinned. Simulations were undertaken with ground true stand inventory data (1451 hectares)
representing Scots pine (Pinus sylvestris), Norway spruce (Picea abies) and silver birch (Betula pendula) stands. Regardless of the climate scenario, it was found that shifting from current practices to thinning regimes that allowed
higher stocking of trees resulted in an increase of up to 11% in C in the forest ecosystem. It also increased the C in the
timber yield by up to 14%. Compared to current climatic conditions, the mean increase over the thinning regimes in the total
C stock in the forest ecosystem due to the climate change was a maximum of 1%; but the mean increase in total C in timber
yield over thinning regimes was a maximum of 12%. |
