DOWNLOAD EBOOKExcerpt from Growth and Yield of Western Hemlock in the Pacific Northwest Following Thinning Near the Time of Initial Crown Closing At almost any year during the first 25 years of a young forest stand, the manager could thin to specified distances between trees (spacing). Both the stand age and the spacing between remaining trees are subject to the manager's choice. We define two thinning ages here.

DOWNLOAD EBOOKSilvicultural 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.
