This report presents the impact of using a portable in-woods chipper to chip red- and grey-stage mountain pine beetle-infested lodgepole pine (Pinus contorta) from the perspective of chip quality, pulping (thermomechanical and kraft) and pulp quality. In addition, the costs of chipping were determined and compared.

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. It examines lodgepole pine (Pinus contorta) that has been attacked and killed by mountain pine beetle (Dendroctonus ponderosae) and which goes through several stages (red and grey) following the attack. Wood moisture content decreases rapidly, typically to below fibre saturation point. As a consequence, the wood responds differently in both the chipping and pulping processes. Research on beetle-attacked wood has shown that many physical properties are not affected; wever wood-water interactions have not been studied in detail. In the two parts of this study, the sorption behaviour of beetle-killed wood in comparison to green wood is examined, and the influence of utilization of dry beetle-killed wood on kraft pulping operations and pulp quality is explored.--Includes text from Government of Canada publications site and from document.

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.
