Some 16% of the Bavarian State forests consist of Norway spruce (Picea abies) stands, which are critical from the ecological point of view and are very susceptible to abiotic and biotic damages. With regard to nature-orientated forest management one aim is to transform pure needle (conifer) monocultures into stands with deciduous tree species (in this case beech, Fagus sylvatica), mainly, to see if this increases the stand structure and biological diversity. To test this hypothesis within a short research period, it was necessary to examine different stages of the conversion process.
