Book Description
This is a compilation of three reports addressing market durability issues with products made from lodgepole pine that has been affected by mountain pine beetle (MPB) infestation. The first report describes the establishment of accelerated field tests to determine the decay resistance of blue-stained post-MPB lodgepole pine sapwood and non-stained sapwood with reference samples of Scots pine sapwood. The second is a comparative technical review of the nature of blue stain in post-MPB wood and the differences between blue stain, mould, and decay. The final report answers frequently asked questions about blue stain on Canadian wood products, including whether it affects construction-related properties.

Assessing the Shelf Life Attributes of Mountain Pine Beetle-killed Trees
Author: S. Magnussen
Publisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 34
Book Description
In 2006, a total of 360 lodgepole pine trees were destructively sampled from 45 sites that had been killed by mountain pine beetle (Dendroctonous ponderosae Hopk.). The trees were sampled from the Sub Boreal Spruce (SBS) Biogeoclimatic zone within north central British Columbia. The trees were distributed evenly across the geographic areas as well as across a sample matrix that included three classes of time since death, three classes of diameter at breast height, and three classes of soil moisture regime. A previous report described the procedures used to the collect the data and summarized the data collected for each of the sample trees. The current study analyzes the data and presents a detailed assessment of the changes in the wood quality attributes of mountain pine beetle-killed trees that occur within 5 years since death.--Includes text from document.

Mountain Pine Beetle Initiative Interim Report 2005

Publisher:
ISBN:
Category : Technology & Engineering
Languages : en
Pages : 68
Book Description
This report highlights past delivery of the land-based programs and progress of mountain pine beetle research during 2003 & 2004 by the Mountain Pine Beetle Initiative, a six-year program established to address the mountain pine beetle epidemic in western Canada and to reduce the risk of future such epidemics. After an introduction on the epidemic and the Initiative, the report summarizes the accomplishments of the Private Forestlands Rehabilitation Program, the Federal Forestlands Rehabilitation Program (First Nations, National Parks, and Other Federal Forestlands components), and the research & development program (including research on ecology, forest economics, socio-economic processes & risk reduction). Finally, the next steps in the land-based and research & development programs are discussed.

Change in Wood Quality and Fall Rate of Trees Up to Ten Years After Death from Mountain Pine Beetle
Author: Kathy J. Lewis
Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 40
Book Description
Despite the history of mountain pine beetle (Dendroctonous ponderosae Hopk.) outbreaks in British Columbia, including the outbreak in the mid 1980s that affected timber supply in the Quesnel Timber Supply Area, little was known about the post-mortality rate of deterioration of wood quality and quantity, and the rate of change in stand structure due to fall of dead trees. This study used dendrochronology to crossdate pine killed by mountain pine beetle to determine the exact year of mortality and to characterize decay and degradation in factors of wood quality and quantity over time.--Includes text from document.

Heat Disinfestation of Decay Fungi Found in Post-mountain Pine Beetle Wood
Author: Adnan Uzunovic
Publisher:
ISBN:
Category : Nature
Languages : en
Pages : 22
Book Description
"This research focuses on studying the heat tolerance of sap-rot and heart-rot fungi found in beetle-killed wood. Specifically, the authors evaluate the 56/30 schedule and other temperature/time combinations. They also investigate whether slow air-drying increased the heat tolerance of the fungi. The generated data are expected to fill an important science gap on the fungi found in beetle-affected trees."--Document.

The Case for Tall Wood Buildings
Author: Michael Green
Publisher: Blurb
ISBN: 9781366377418
Category :
Languages : en
Pages :
Book Description
This book describes a new structural system in wood that represents the first significant challenge to concrete and steel structures since their inception in tall building design more than a century ago. The introduction of these ideas is driven by the need to find safe, carbon-neutral and sustainable alternatives to the incumbent structural materials of the urban world. The potential market for these ideas is quite simply enormous. The proposed solutions have the potential to revolutionize the building industry, address the major challenges of climate change, urbanization, and sustainable development and to significantly contribute to world housing needs.
