Explores the relationships between forest management activities and timber quality. Sessions were organized to explore models and simulation methodologies that contribute to an understanding of tree development over time and the ways that management and harvesting activities can influence the quality of timber products recovered from those trees. Five keynote addresses, 29 plenary presentations, and 16 poster presentations covered the full breadth of forest growth and timber quality issues related to forest management. These proceedings comprise 19 papers based on presentations and posters, plus 28 abstracts for presentations. Also includes abstracts and slides from the presentations prepared by three keynote speakers. Illustrations.

The Tree Faller’s Manual is an essential handbook for forest operators and others who need to fell trees manually using a hand-held chainsaw. This manual builds on the information provided by the Chainsaw Operator’s Manual. Tree felling is a high risk activity. Many fatalities and serious injuries have occurred as a result of being struck by falling trees, dislodged tree limbs or other dangers in the area. Most of these accidents are caused by using unsafe felling techniques and not following safe work procedures. This manual will guide the faller to safer work techniques. The manual is based on the national competency standards for the forest and forest products industry where tree-felling is covered using three categories: basic, intermediate and advanced. Basic tree felling applies to trees that are relatively small, with a single stem and no defects. Intermediate tree felling covers trees with single or multiple stems, limited defects, and lean and weight distribution that can be adapted to felling direction. Advanced tree felling applies to larger and more complex trees and includes trees deemed to be more hazardous. Workplace safety, risk assessment and site preparation are included along with the theory, techniques and tools for each of the tree-felling categories.

Avalanche dynamics equations are used to estimate flow heights, velocities, specific thrust pressure, maximum specific weight of avalanche debris, and runout distance for 12 avalanche case studies from the Colorado Rocky Mountains. Suggestions are made for using this engineering approach for avalanche zoning and land use planning.
