"A healthy forest, untouched by forestry technology, is made up of a strange mixture of vegetation. Alongside well-defined areas of noble trees, conditions of apparent chaos can be found, which can best be described as irregular confusion. People who are not aware of the importance of the balance in Nature, of which the forest is a part, want to clear areas of everything they do not consider to be useful. A great deal of sensitive concern and observation is necessary to begin to understand why Nature depends on an apparently chaotic disorder."
