Download or read book Growth of Douglas-Fir Near Equipment Trails Used for Commercial Thinning in the Oregon Coast Range written by United States Department of Agriculture and published by CreateSpace. This book was released on 2015-06-26 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil disturbance is a visually apparent result of using heavy equipment to harvest trees. Typical types of soil disturbance from ground-based harvest include displacement, rutting, and compaction. Subsequent consequences of soil disturbance to growth of trees, however, are variable and seldom quantified beyond short-term effects. Despite a persistent need to further quantify tree response to soil disturbance, policies and practices intended to reduce or avoid soil disturbance from logging have been widely adopted on both public and private forest lands in the Pacific Northwest (Adams 2005).

Download or read book Growth of Douglas-fir Near Equipment Trails Used for Commercial Thinning in the Oregon Coast Range written by and published by . This book was released on 2007 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil disturbance is a visually apparent result of using heavy equipment to harvest trees. Subsequent consequences for growth of remaining trees, however, are variable and seldom quantified. We measured tree growth 7 and 11 years after thinning of trees in four stands of coast Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb. Franco)) where soil disturbance was limited by using planned skid trails, usually on dry soils. The three younger stands had responded to nitrogen fertilizer in the 4 years before thinning, but only one stand showed continued response in the subsequent 7- or 11-year period after thinning. The most consistent pattern observed was greater growth of residual trees located next to skid trails. The older stand also showed greater growth in trees located next to skid trails, whereas tillage of skid trails failed to benefit growth of nearby residual trees for the first 7 years after tillage. We conclude that traffic that compacted soil only on one side of residual trees did not reduce growth of nearby trees.

Download or read book Guidelines for Precommercial Thinning of Douglas-fir written by Donald L. Reukema and published by . This book was released on 1975 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Production of merchantable wood in even-aged Douglas-fir stands can be increased substantially by precommercial thinning. Guidelines for, and gains from, precommercial thinning both strongly depend on the size of trees wanted at the first commercial cut; the larger this size, (1) the fewer trees should be left after precommercial thinning, (2) the greater is the maximum age or tree size at which precommercial thinning is practical, and (3) the greater is the gain is usable yield from precommercial thinning. Also, generally, the longer the time required for a stand to reach commercial size without thinning, the greater the gains from precommercial thinning. These and other considerations are discussed, and procedures are recommended.
