Book excerpt: Excerpt from Results of Shelterwood Harvesting of Douglas-Fir in the Cascades of Western Oregon U. S. Forest Service experience has shown that clearcutting Douglas-fir in the Pacific Northwest does not always result in successful regeneration, either natural or artificial. Where regeneration has failed, this has been due to such causes as temperature extremes and drought. Failures, primarily at higher elevations in the Oregon Cascades, led the Forest Service to try shelter wood harvesting, beginning in 1962, as a possible alternative to clearcutting. I surveyed these initial shelterwood stands in summer 1970 with two main objectives. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.
