Uttag av kvalitetsvirke a björk - potential och problem
The purpose of this report is to illustrate potentials and problems with withdrawal of quality timber of birch. The purpose is also to describe possible ways to increase available quantities of quality timber. Former research is reviewed as introduction. The study begins with a prognosis of future volumes of birch timber based on consequence analyze by Swedish Forestry Agency. To illustrate the importance of active maintenance, two stands are estimated and simulated in the Heureka module StandWise. At the end of the report the results of the simulations and different ways to increase production of quality timber of birch are discussed. Finally topics for further research are suggested.
