This summary report presents the main findings of a study of systems for the production of aspen veneer logs in northern Ontario. The case studies, which took place in 2001 and 2002, covered four types of operations: in-woods chipping, satellite yards, roundwood merchandizing at roadside, and roundwood production at the stump. The advantages and disadvantages of each system for the production of veneer logs are given, along with production cost estimates for each system. A report presenting further productivity and quality data, and a detailed cost analysis (in an Excel spreadsheet) are available to FERIC members and partners on request.
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.
