verjüngen und vielfältig mit anderen Baumarten zu mischen, der relativ geringen
Risikoanfälligkeit und der durch das Buchenholz verbreiterten Sortimentspalette,
die von den Forstbetrieben angeboten werden kann.
Ein großflächiger Waldumbau in Richtung Buche ist nicht zuletzt auch vor
dem Hintergrund der damit einhergehenden langfristigen Liquiditätsprobleme
kritisch zu sehen. Ob und inwieweit die laufenden Klimaänderungen hier zu einer
Neubewertung Anlass geben, ist an anderer Stelle zu diskutieren.

Abstract
As a characteristic tree species of potential natural forest communities on many
sites in Germany, beech is accorded a high priority in nature conservation. In
forestry, it also has an economic value: in particular it is managed with the aim of
reducing risks in stand management, but also of expanding the range of timber
assortments.
However, a critical analysis of economic results of net yield calculations and
economic comparisons of different enterprises for different tree species shows
that, despite the recent comparatively favourable market conditions for beech
stemwood, even today beech continues to realise a lower profitability – a lower net
yield – than Norway spruce, for example. Furthermore, in the last two to three
years the market developments have been unfavourable for beech.
Not even the much higher risks in the management of Norway spruce have
brought about a reversal of this trend. Yet beech will continue to have a broad
distribution in the future, especially on colline and sub-montane sites with better
nutrient status, primarily because beech can be regenerated naturally with ease and
grown in mixture with a diversity of species, because of its relatively low risk of
susceptibility and the range of beech wood assortments that forest enterprises can
supply.
A critical appraisal of the large-scale conversion of forests to beech is
necessary, not only in view of the long-term liquidity problems associated with it.
A discussion of whether and to what extent the ongoing climate change presents
an occasion for a renewed evaluation also is required.
