In this investigation we analyzed pairs of uneven-aged vs even-aged managed Norway spruce long term plots. The plots were established as parallel plots in 1920-1940’s and are followed by frequent measurements over a period of 50 to 90 years to get knowledge about growth, stability and forest management . The uneven-aged plots were managed with selection system, while the even-aged plots were managed with thinning from below. Diameters of all trees and heights of sample trees are measured. The diameters of harvested trees were 17 % larger than the remaining trees and indicate thinning from above. We experienced about 20 % lower volume production in the uneven-aged forest compared with the yield capacity (YC) with the largest deviation at the most productive sites (YC >9 m3/ha/yr). Selection system based on natural regeneration is favorable at vegetation types with easy regeneration conditions. We experienced problems to maintain a J-shaped diameter distribution at most sites with uneven-aged management due to too small harvesting (selection system), dense stands, and small natural regeneration. It is difficult to balance between dense productive stands and initiating natural regeneration under Norwegian conditions. However, problems with stability are also observed in even-aged stands.

Polymerase chain reaction (PCR), a biochemical technology that generates copies of a particular DNA sequence, has revolutionized life sciences. Thirty years after its development in 1983, PCR is a standard and indispensable technique in medical and biological research for a variety of applications. Compared to many other fields, novel PCR applications and sequencing platforms have been rather slowly adopted by research groups engaged in wood protection. Regarding laboratory and field experiments for testing the efficacy of wood treatments, this opinion article discusses the potential of 2nd generation PCR applications and sequencing platforms for profiling 1) the growth and activity of wood decay microbes upon feeding and detoxification of treated wood, and 2) for recording the successional changes that take place in microbial community along with progress of wood decay.
