Book Description
This paper presents the research analysis of visible/near infrared spectroscopy in identification of decay in mountain pine beetle affected lumber. The research premise was based upon the concept that using visible/near infrared spectroscopy would aid in improving more immediate decay detection in lumber. Because of the increasing amounts of decay, specifically sap-rot, and the increase of lumber production within the planer mills, soley relying on visible detection of the rot is not feasible. Although automated detection systems do use colour cameras, this research analysis was to provide information on whether the process could be improved upon in decay detection for the lumber graders.

Book Description
This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle (MPB) epidemic. It presents the results of pilot plant Kraft and mechanical pulping trials that were conducted to determine the influence of time-since-death (TSD) of (MPB)-killed lodgepole pine on pulping and pulp quality. Samples included trees of red, grey and late grey attack stages as well as unattacked trees; sample sites were established in three different biogeoclimatic subzones in British Columbia in order to account for natural variability. Prior to pulping, samples were tested for wood and fibre properties as well as chip quality. Kraft and thermomechanical (TMP) pulping parameters were monitored, pulp quality was determined, and sheet structure was evaluated by scanning electron microscopy.--Includes text from document.

Book Description
The issue of how to maximize the value recovery from beetle-attacked pine wood is critical to the wood panel industry in British Columbia. This paper discusses the pilot plant tests and mill trials that were conducted to quantify the impact of using mountain pine beetle (MPB)-attacked lodgepole pine (Pinus contorta Douglas) wood on green veneer processing to determine of it makes economic sense to sort and process MPB logs separately from normal logs of SPF (spruce-lodgepole pine-alpine fir) mix for plywood manufacturing.--Includes text from document.

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.

Book Description
This study is part of a series of research papers that explore the biological, social, and economic aspects of British Columbia's mountain pine beetle epidemic. The purpose of this report is to identify and characterize the fungal species that may potentially damage wood and decrease its market values. It focuses on the characterization of 40 different basidiomycetous fungi that were isolated form 12 different sites across British Columbia. Fungi were isolated from mountain pine beetle-infested lodgepole pine trees in green, red, and grey stages from each of the 12 sites.--Includes text from Government of Canada publications site and from document.

Book Description
"This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.
