This book was released on 1975 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial thinnings in a 50-year-old stand of nearly pure, well stocked, even-aged western hemlock (Tsuga heterophylla) on the Hemlock Experimental Forest near Hoquiam, Washington, began in 1952 and ended in 1968. The experiment consisted of two replications of four different thinning treatments, high and low thinning, both at frequent and infrequent intervals. Volumes removed in thinning ranged from 41 to 107 percent of the gross cubic volume increment for the experiment. Field layout of the experiment and methods of analyses are discussed in detail. All thinned treatments had a higher growth percent than their respective control areas. Thinning also indicated distinct improvements in average diameter increment and realized increment, which is the volume harvested in thinning plus the volume added to the growing stock. Gross growth and mortality were not greatly affected by thinning. Although thinning in general produced positive results, no single type of thinning treatment could be isolated as the 'best' method.

Book excerpt: Excerpt 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.

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.
