Clear-cuts can be used to mimic natural disturbance. Specifically, patch cuts (a small clear cut), can increase biological diversity, reduce fire risk, and increase forest resiliency. Certain species, such as Douglas Fir, do best if the intention is to regrow Douglas Fir with clear-cuts (common western commercial forestry practice). Also, a selection harvest in a Douglas Fir stand would favor shade tolerant species such as fir, hemlock, and spruce. Accordingly, certain choices need to be made addressing a variety of economic and ecological considerations.
