In 1990, a storm damaged wide forest areas in middle Europe, especially in south Germany. Research proved that most of the damages resulted from mono-culture forestry of even-aged trees on unstable natural sites. Therefore, the state forest administration of Baden-Wuerttemberg decided to introduce a forest management strategy conforming to natural cycles. To find out, what impact this had on current and future availability of timber resources for the sawmilling industry, forest inventory results from 1987 and 1999 were compared with each other. Changes in both current availability and future logging potentials could be determined, which are in contrast to the current raw material needs of the sawmilling industry.
