Options for reducing "waste" in the management of old growth forests
1977
Hrubes, R.J. | Rensi, G.
Some critics of the USDA Forest Service's timber management policies claim that retention of old growth is "wasteful" because replanting to more productive stands is precluded. such other factors as political feasibility and resource self sufficiency, however, weigh in favor of not accelerating the rate of old growth harvesting. three possible options for resolving the issue are to determine levels of nondeclining yield on a regional basis rather than by smaller local units, to intensify management of young stands, and to accelerate harvest of old growth but release the logs to market at a controlled rate.
