He credited the importance of economic considerations over ecological conditions, which would suggest smaller-scale management units. Early in the twentieth century, silvicultural books began to formally 38 a critique of silviculture: manag ing for complexity acknowledge scientific findings as a basis for silvicultural decision making. For example, Mayr (1909) first presented scientific data in his silviculture book. Morosov (1920) included the first treatment of site and stand-type classifications.

All silvi- Silvicultural systems are a set of basic management practices to regulate stand structure and species mixtures. 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.

Instead of dealing with logistical complications of the seedtree system (more difficult layout, multiple harvesting operations), harvesting units were laid out as long, narrow strips. Initially, strip clearcutting often caused windthrow problems in adjacent stands. In recognition of this, harvested strips were then oriented according to the prevailing wind direction in wind-exposed areas (Hausrath 1982). Widespread implementation of strip clearcutting required landscape considerations (to prevent wind damage and facilitate harvesting operations).
