Abstract
FERIC's study examined the potential of intensive site preparation based on a double treatment (brushcutting plus harrowing) as an alternative to expensive mulching techniques for stand conversion. Although the proposed technique did not work the soil as completely as mulching, it significantly decreased treatment costs.

Abstract
In today’s sawmills, the accurate rotation and positioning of the logs, prior to chipping and sawing, is an essential component in maximizing the volume of the lumber produced from each log. Previous studies, and the work conducted here, have shown that the common methods of rotating the logs as they enter the canter line can have large errors leading to very significant losses in lumber recovery, especially for small, swept or crooked logs. Sawmills are also moving to higher and higher processing speeds to reduce production costs, making log positioning even more difficult. In this project a real-time camera based system was developed that measures the incremental rotation of each log (as it is being rotated by the log rotator) and provides feedback that can be used to control the degree of rotation with much greater accuracy. In addition, a log rotation verifier was developed that, using the existing mill pre- and post-rotation scanning systems, measures the actual rotation of the log to continuously verify the accuracy of the system.

Abstract
Historically, forest roads on the B.C. coast have on occasion been constructed using stumps and log cribs to retain the road fill on steep slopes. However, experience has shown that failures in road fill may occur after several years, often due to root strength deterioration. To ensure slope stability is maintained when building forest roads, a design process needs to be developed when utilizing logs and stumps to retain the road fill. To do this, more information is needed, specifically load carrying capacity and failure characteristics of old-growth stumps on coastal B.C. terrain. This report presents the results of the trials conducted in order to determine the strength of typical old-growth Douglas-fir stumps.

Abstract
Compared to slower growing trees like spruces, hybrid poplars and selected aspens grown in these plantations are ready for harvest in less than 20 years. The technology development specialists established this a mixed wood crop to evaluate how short-rotation or fast-growing tree crops (123 to 17 years to maturity) could sustain and expand the bioenergy sector. High-yield crops like these are crucial for the sector, which relies on woody biomass to produce clean energy.
