Book excerpt: Lodgepole pine (Pinus contorta Dougl.) forests make up approximately 35% of British Columbia's forested land base and accounty for 25% of the province's total volume harvested. Mountain pine beetle (Dendroctonus ponderosae Hopk.) is currently B. C.'s most devastating forest insect and it has wrought more destruction in mature lodgepole pine forests than any other forest insect. In an attempt to deal with the pine beetle infestation, an accelerated harvesting of pine stands damaged with this insect has been ordered by B. C. Ministry of Forests throughout the north central part of the province. Mature lodgepole pine trees attacked by the pine beetle are afflicted through the introduction of Ophiostoma piliferum, a fungus that causes blue stain in the sapwood. This preliminary study was undertaken to quantify the costs associated with thermechanical and chemithermomechanical pulping and brightening the mechanical pulps produced from blue-stained and sound lodgepole pine chips.--Document.
