Dengler relied heavily on increased scientific understanding of the influence of site conditions on forest development and other ecological relationships for making silvicultural decisions (Mayer 1984). These writings emphasized that silviculture should not be simply viewed as long-rotation agriculture but should base its decisions on an understanding of plant communities and ecosystem dynamics, a view that is still widely held in central Europe today (Mayr 1984; Burschel and Huss 1997). A viewpoint that has received repeated attention in forestry teaching in the twentieth century is the development of the “permanent forest” (Dauerwald) movement.

The late seventeenth century was the beginning of a period of rapid change for the inhabitants of central Europe, and forest management went through a period of intense transition to accommodate these changes. After the Thirty Years’ War (1618–1648), the increased human population and demands of the emerging mining, glass, and ship-building industries had led to desolate forest conditions in many regions. Forests with low timber volume and value, and areas degraded to the point where they no longer supported trees, became a common sight in the central European landscape (fig.

3). The formal education ensured that foresters were aware of the full variety of common silvicultural practices, but it also meant that for educational purposes these practices had to be categorized. As part of their education, foresters were taught new, modern technologies and practices and then trained to select from this set of management practices. historical context of silviculture 25 Despite educational needs to categorize, the variety of local ecological, economic, and social conditions in Europe resulted in the widespread application of a few dominant silvicultural systems in the nineteenth century (Spurr 1956), but a large number of modifications of these systems (mostly small-scale and locally applied) were still recognized.
