Abstract
The objective of this project is to investigate the effects of intensity in regenerations and various thinning programs on timber quality in planted Norway spruce. Effects of regeneration treatments and thinning program on timber quality will be quantified in such a way that it can be used in a silvicultural simulation system which is under development. To not only include volume production but also development of value in planning instruments will probably increase the long-term profitability of Norway spruce plantations in Scandinavia. The hypothesis is that silvicultural treatments affect growth and morphology of Norway spruce in a predictable way and this will also affect timber quality. Growth and timber-quality will be investigated in old experiments with different spacings, gaps of different size in plantations and in experiments with different thinning programs.
