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.
