36 a critique of silviculture: manag ing for complexity Lack of scientific understanding about the importance of local site adaptations and/or the desire of silviculturists for self-promotion and regional or national recognition were often behind the generalization of local practices. A lack of ecological understanding was likely responsible for the application of silvicultural systems to different species within a region (see discussion about shelterwood and Femelschlag above, tab. 1). Applications of inappropriate silvicultural practices were less quickly discarded when they were forced upon a region through regulatory means, commonly by dominant or well-recognized silviculturists or administrators.

By the end of the eighteenth 18 a critique of silviculture: manag ing for complexity centrury, Hartig (1791) voiced concerns that differential growth rates and competitive abilities would lead to forests that were dominated by a single species. The lack of success of mixed-species management was subsequently used as a justification to manage for single-tree species (Hausrath 1982; Mantel 1990). The onset of economic liberalism and its focus on productivity further strengthened the trend. The shift toward monocultures had a variety of impacts on silvicultural approaches and practices.

They are labeled after the reproduction cutting method, but include all aspects of stand management. Even-aged systems promote regeneration of closely aged trees. The coppice system regenerates the forest from sprouts or root suckers of cut trees. The regeneration develops in a fully exposed microclimate in the clearcutting system after removal of all trees from the previous stands. In the seed-tree system, cuts are similar to the clearcutting system, except that a small number of canopy trees are left to provide seed.
