This book was released on 2016 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Farwell Canyon project was established within two Douglas-fir (Pseudotsuga menziesii) stands in the Very Dry Mild Interior Douglas-fir (IDFxm) biogeoclimatic subzone in the Cariboo Region, British Columbia in 2001. The project goals were to improve forage for wildlife and livestock (i.e., increase vascular plant cover), improve the growth of the residual stand by reducing inter-tree competition, shift the plant community composition to one that is more typical of open forest condition, and improve the resiliency of the stand to catastrophic fire. From a timber management perspective, the goal was to increase individual tree growth by logging and thinning while maintaining overall stand-level growth. To achieve these goals, treatment combinations of "modified" logging, pre-commercial thinning, and burning were applied to return the forest to a more open condition that is typical of Douglas-fir forest adjacent to grassland in the IDFxm. Four treatments were applied to one or both blocks: 1. No-treatment areas were established to serve as untreated controls for demonstration and comparison purposes. 2. The logging treatment used a fellerbuncher and grapple skidder combination to apply a "BDq" approach that left a residual stand basal area of about 15 m2/ha (B=residual stand basal area; D=largest-diameter trees; q=diminution quotient). The merchantable utilization was reduced to 12.5 cm diameter at breast height (dbh) for Douglas-fir. 3. The logging treatment was followed by manual thinning of juvenile stems (

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.

This book was released on 2002 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental project was established in 1957 at a site about 20 kilometres north-west of Nakusp, British Columbia, to study the effects of partial cutting on complex stands in the interior cedar-hemlock zone. This report presents results observed over the first 40 years of the experiment and updates the 15-year results reported by Thompson (1977). Results are presented for individual trees & the entire stand with regard to growth, mortality, and stand development in response to three partial cutting treatments: improvement cut, diameter-limit cut, and salvage cut.
