Available in PDF, EPUB and Kindle. Book excerpt: Forests in the United States contain a significant amount of small-diameter and underutilized material. These overstocked stands not only increase the risk of insect, disease, fire, and drought damage, but also are costly to remove. Finding economical and marketable uses for small-diameter and underutilized material would alleviate these problems while improving watershed health and providing economic opportunities for local communities to help offset forest management costs. An extensive research program at the Forest Products Laboratory of the USDA Forest Service is focused on searching for economical and marketable uses for small-diameter material. The projects described in this report range from conserving timber through improving sawing technology to developing businesses for using small-diameter material.

This book was released on 2009 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Log moisture content has an important impact on many aspects of log home construction, including log processing, transportation costs, and dimensional stability in use. Air-drying times for house logs from freshly harvested trees can depend on numerous factors including initial moisture content, log diameter, bark condition, and environmental conditions during drying. In this study, we evaluated air-drying properties of young-growth Sitka spruce (Picea sitchensis (Bong.) Carr) and of western hemlock (Tsuga heterophylla (Raf.) Sarg.) from logs harvested in southeast Alaska. For each species, we considered inside storage in a warehouse vs. outside storage, as well as debarked logs vs. logs with bark remaining, resulting in four experimental treatments. We considered moisture losses after 8 and 12 months of air drying. There was considerable moisture loss for Sitka spruce logs, and much of the drying occurred during the first 8 months. Fastest drying rates for both species were for peeled logs with inside storage. Western hemlock logs showed higher moisture content and greater moisture content variation (vs. Sitka spruce), and in most cases would require additional drying beyond the 12-month study period to produce satisfactory house logs. Results of this study are significant because they can help entrepreneurs determine appropriate levels of capital investment (e.g., land, covered storage, debarking equipment), as well as whether to dry and process logs in southeast Alaska vs. some other location. This study found that a leading option for local producers would be to peel Sitka spruce logs, then air dry indoors for between 8 and 12 months. Another effective strategy would be to peel western hemlock logs, then air dry indoors for 12 months.

This book was released on 2008 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southwestern piñon-juniper and juniper woodlands cover large areas of Arizona, New Mexico, Utah, and adjacent Colorado. Ponderosa pine forests are the most common timberland in the Southwest. All three ecosystems provide a variety of natural resources and economic benefits to the region. There are different perceptions of desired conditions. Public and private land managers have adapted research results and their observations and experiences to manage these ecosystems for multiresource benefits. Ways to mitigate the threat of wildfires is a major management issue for these ecosystems, and the wide-spread piñon mortality related to drought and the bark beetle infestation has heightened concerns among managers and the general public. In addition, the impacts of climate change on these ecosystems are a growing concern. As a step in bringing research and management together to answer some of these questions, workshops concerned with the ecology, management, and restoration of piñon-juniper and ponderosa pine ecosystems were held in St. George, Utah in 2005 and in Albuquerque, New Mexico in 2006. The combined proceedings from these two workshops contain papers, extended abstracts, and abstracts based on oral and poster presentations. Some topics included forest and woodland restoration treatments and their impacts on fuels, wildlife, and other ecosystem components, watershed management, insect infestations and drought, wood utilization, landscape changes, basic ecology, and more.

Download or read book Small diameter Trees Used for Chemithermomechanical Pulps written by Gary C. Myers and published by . This book was released on 2003 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: To restore and maintain forest ecosystem health and function in the western interior of the United States, many small-diameter stems need to be removed from densely stocked stands. In general, these materials are underutilized. Information on the properties of these resources is needed to help forest managers understand when timber sales are a viable option to accomplish ecosystem management objectives. Providing proof that this small-diameter material yields quality pulp would help increase its value and therefore help remove it from the forest. This study examines the acceptability of the small-diameter resource as a raw material for high-yield chemithermomechanical pulping (CTMP), which has the potential for improved fiber characteristics and paper strength compared with those of thermomechanical pulping (TMP). Pulps using CTMP were prepared from lodgepole pine and mixed Douglas-fir/western larch sawmill residue chips; lodgepole pine, Douglas-fir, and western larch submerchantable logs; and lodgepole pine, Douglas-fir, and western larch small trees. These small-diameter pulps were compared with commercially obtained sawmill residue chips of a Douglas-fir/western larch mixture and lodgepole pine. These pulps were also evaluated to see if CTMP improved the properties of the final product compared with products made using TMP. Compared with the controls, the CTMP prepared from Douglas-fir and lodgepole pine small trees and Douglas-fir submerchantable logs consumed more electrical energy during pulp preparation and had higher paper strength properties and lower optical properties. Also compared with the controls, lodgepole pine submerchantable logs consumed about the same electrical energy and had marginal strength properties and higher optical properties. Western larch submerchantable logs and small trees had the lowest electrical energy consumption of all pulps tested, low strength properties, but some of the higher optical properties. Western larch submerchantable logs and small trees appear to be unsuitable for CTMP. For the majority of the materials, CTMP improved the properties of the final product compared with corresponding TMP.

Download or read book Review of Log Sort Yards written by John Rusty Dramm and published by . This book was released on 2002 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides a general overview of current log sort yard operations in the United States, including an extensive literature review and information collected during on-site visits to several operations throughout the nation. Log sort yards provide many services in marketing wood and fiber by concentrating, merchandising, processing, sorting, and adding value to logs. Such operations supply forest products firms with desired raw materials, which helps improve their bottom line by reducing the number of marginal logs processed. Ultimately, sorting logs leads to better use of the available timber resources. Successful log sort yards are self-sufficient and have well-established markets and a steady supply of wood. Log sort yard concepts and analyses described in this report have broad applications.
