Example text

Here, the zoning approach reflected itself in intensive management of stands for single products. In most parts of Europe, the variety of desired wood products, such as small and large construction timber, was more compatible and forests could be managed for multiple products. Therefore, during the later Middle Ages, a combination of thinning and final harvesting operations, often in conjunction with mixed-species management, ensured the supply of a diverse range of products (Hausrath 1982; Hasel 1985; Mantel 1990).

Owners of small farms not only valued that these forests could act as a “savings account,” but also valued the frequency of timber harvests for the constant cash-flow they provided. Furthermore, the cuttings could be done during the less busy winter months, which allowed implementation of the frequent intensive forest management practices necessary to maintain the uneven-aged stand structure (Mantel 1990). , Emmental in Switzerland or the southern Black Forest in Germany) are composed of shade-tolerant tree species, such as European silver fir.

Another prominent example of a dogmatic attempt to apply a single silvicultural system to a whole region was Christoph Wagner’s version of edge shelterwood (Blendersaumschlag) (Wagner 1912). Wagner developed the system while employed by a private landowner in southwestern Germany. Later, after becoming state forester of Württemberg, he encouraged a regulation that required implementation of the system on all state forest lands (Vanselow 1963; Mantel 1990). The fact that cutting patterns in edge shelterwoods were based solely on windthrow concerns and ignored the local ecological conditions and tree species composition was recognized by the forestry profession, and the edge shelterwood (Blendersaumschlag) was quickly abandoned (Mayer 1984; Mantel 1990).
