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 British Columbia's market kraft and mechanical pulps, which are produced from interior spruce, pine and fir (SPF) and are significant for the province's economy. The chips used to produce SPF pulp are a residual material from lumber operations and are traditionally composed of approximately 30% spruce, 65% lodgepole pine and 5% subalpine fir. However, due to the mountain pine beetle epidemic in the province, this balance is subjected to climb to a pine content of 80% to 90% as salvage harvesting of attacked and dead lodgepole pine stands increases. This study quantitatively and qualitatively defines pulp quality changes with changing chip mixture in order to increase understanding of problems that can be anticipated with changing chip quality needs.--Includes text from Government of Canada publications site and from document.
