Available in PDF, EPUB and Kindle. Book excerpt: The effectiveness of precommercial crop tree thinning was investigated by thinning crop trees of paper birch, yellow birch, and sugar maple to two intensity levels at 8 years of age. Analysis of covariance on post thinning growth measurements taken 7 years later indicated a significant increase in diameter and crown-diameter growth, with the pattern of response varying by species. The study suggests that a uniform crop-tree thinning treatment for a stand composed of species with varying tolerances will rarely produce the best response for all the species.

Available in PDF, EPUB and Kindle. Book excerpt: S2The purpose of this paper is to provide a practical guide to the management of paper birch stands for timber production. Both the establishment of new stands and the culture of existing stands are covered. Background information on paper birch silvics, silviculture, and management is followed with a set of prescriptions describing specific treatments to be applied for a range of stand conditions and management objectives. A limited amount of information is also provided on the management of paper birch stands for aesthetic and other purposes (fig 1).S3.

Available in PDF, EPUB and Kindle. Book excerpt: Distribution-of-cut guidelines describe the amount of stand density to be removed from broad size classes of trees to attain a target residual stand density and stand structure. Current guides for thinning Allegheny hardwoods recommend that 75 percent of the cut relative stand density be taken from below the average stand diameter and 25 percent from above. These guides are well suited for maximizing production of wood volume and stand worth in 50-year-old stands. In 70-year-old stands, previously thinned or not, wood production is maximized by distributing the cut so that the entire cut is from below the average stand diameter. Stand worth is maximized at 25 to 50 percent cut from below. Current guides for thinning 70-year-old Allegheny hardwoods are a compromise between the two at 75 percent cut from below. Only at this percentage is black cherry retained at sufficient levels to fully regenerate a site.
