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.

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.

"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.
