Beech red heart: avoid or use it?
2001
Richter, J.
In beech management, the development of red heart is still a big problem. In 27 stands in Sauerland, felled stems were controlled for read heart at the top end. The stems were divided into three age classes (120, 120-150 and 150 years) and four top diameter classes (30-39, 40-49, 50-59 and 60 and more cm). The increase in the amount of red-hearted stems was steep between the diameter classes and low between the age classes. So the effect of growing diameter is much more important an that of growing age, and the possibilities of avoiding red heart by shorter rotation times seen to be low. - The comparison from trees with or without spiral growth shows no differences. Broken branches in the lower crown area favor the development of red heart, but this seems not to be the main cause. Considering the low possibilities of avoiding red heart, forestry should invest in a much more intensive research to develop and increase the us of this type of wood and its marketing.
