Book excerpt: The Lake States of Michigan, Minnesota, and Wisconsin consist of 49.4 million hectares (122 million acres) of land, 19.8 million hectares (49 million acres) of which are forested, with 6% of those having been removed by law from timber production. Aspen (Populus tremuloides) is an important component of this resource. In recent years, a concern that the aspen cut will exceed its growth has surfaced. That is, Will the aspen supply be adequate to support the growing solid-wood, composite, and paper industries in the Lake States region? To satisfy the increased demand for forest products, it is expected that much of the future timber supply will be from improved trees grown on managed plantations. It is critical that the mechanical properties of this resource are clearly understood so that alternative uses of this material can be evaluated. A study was conducted using full-size lumber tests on 243 38- by 89-mm (2- by 4-in.; hereafter called 2 by 4 gass) boards cut, using two methods, from 50 logs to determine selected mechanical and physical properties of the Wisconsin-5 hybrid poplar clone. The material was either kiln dried or partially air dried followed by kiln drying. The 2 by 4 gass were assigned grades according to four grading rules: Light Framing, Structural Light Framing, Structural Lamination, and Machine Stress Rating. Results suggest that this poplar clone would produce visually graded material that is similar in properties and characteristics to the native aspen and cottonwood resource. Close to 65% of the material produced made grades of either Standard and better or No. 2. The Machine Stress Rating grade most likely to be produced from this material would be 1450f--1.3E. To avoid excessive degrade as a result of warping during drying, this material should be dried in flitch form.

This book was released on 2015 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Populus tremuloides serves as a highly valued pulp species for the forest industry. Yet its susceptibility to disease, particularly to decay, hinders its use more widely as a lumber species. Trametes pubescens, chosen for its ruderal qualities, broad host and geographic range, is a species of fungus that affects dead hardwoods. Roadside lumber and or timber at a mill site, is all susceptible to colonization by this fungus. To further our knowledge of decay fungi and their effect on the structural qualities of aspen wood, T. pubescens was selected for further study. Sixteen replicates of ten Populus tremuloides wood samples were aseptically inoculated with mycelium of Trametes pubescens. Bi-weekly, two replicates were removed, dried, weighed and tested for modulus of elasticity (MOE) modulus of rupture (MOR) and density."-- from abstract.

Book excerpt: Information about the biology, ecology, and management of quaking aspen on the mountains and plateaus of the interior western United States, and to a lesser extent, Canada, is summarized and discussed. The biology of aspen as a tree species, community relationships in the aspen ecosystem, environments, and factors affecting aspen forests are reviewed. The resources available within and from the aspen forest type, and their past and potential uses are examined. Silvicultural methods and other approaches to managing aspen for various resources and uses are presented.
