Excerpt from Economic Feasibility of Longer Management Regimes in the Douglas-Fir RegionThese arguments have reappeared recently as part of developing a new land management plan for the Tillamook State Forest.4 There the Oregon Department of Forestry is considering alternative forest management prescriptions to protect key habitats and processes in selected areas. Among the alternatives are several that involve longer rotations that provide greater timber revenues over a longer time frame than can be obtained by the short-term high-volume harvest regime currently in operation.This paper describes a study done for the Salmon Anchor Habitat Working Group5 as background to their review of alternative management strategies for the Tillamook State Forest. I review the evolution of management regimes in the Pacific Northwest and then develop three specific management regimes that encompass the types of alternatives being considered. I also review the management methods and some of the critical assumptions behind the regimes. Finally, I discuss the implica tions for land management and managers.The interest in growing timber for high-quality purposes by using longer rota tions is not unique to the Pacific Northwest. It has been discussed in the context of plantation management in South Africa (craib New Zealand (sutton 1984, Whiteside and others British Columbia (kellogg the Pacific Northwest (barbour and others and southeast Alaska (barbour and others, in press). The general conclusion of this work is that the tradeoffs among rotation length, timber quality, and financial returns depend on the way in which costs are discount ed and whether the computations include the value of amenities associated with longer rotations.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
