Book excerpt: The mountain pine beetle has impacted over 5 million hectares of pine forests in the Rocky Mountains region in the United States. Although some beetle-killed stands are available for salvage harvesting, there are many uncertainties in harvesting beetle-killed stands including safety, costs, recoverable products and their values. These uncertainties impose limitations on the ability of land managers to make timely decisions regarding beetle-killed stand management. This study aimed to quantify the difficulty of harvesting operations in beetle-killed forest stands with various downed-tree proportions. A detailed time study was conducted on a whole tree clear-cut harvest using a ground-based system in western Montana in August 2015. The effects of downed-trees on machine productivity and cost were analyzed using the collected field data. Our results indicated that tree conditions, including standing or down, not only significantly affected the productivity of the feller-buncher, but also affected the unit costs and productivity of the entire harvesting system, changing of the bottleneck machine in a combined felling, skidding and delimbing operation. This research also provided insight into how optimized system configuration may help cope with the increase of harvesting cost caused by the temporal changes in beetle-killed stand conditions, allowing forest managers and practitioners to understand the potential impact of delayed stand management decisions on harvesting costs and outcomes.

Book excerpt: 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.

Book excerpt: "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.
