Abstract
Le trieur Pulpwood Sorter de Simco/Ramic a fait l'objet d'essais dans le but de déterminer s'il était capable d'extraire des copeaux sans écorce destinés à la pâte, à partir de copeaux produits en forêt et contenant des quantités connues d'écorce et d'autres débris. Les essais portaient sur quatre types de copeaux: des copeaux de feuillus provenant d'arbres entiers, des copeaux de résineaux provenant de troncs entiers, des copeaux de résineux provenant d'arbres entiers et des copeaux de feuillus produits par une ébrancheuse-écorceuse-déchiqueteuse à fléaux. Les résultats des essais donnent les proportions de copeaux acceptés et de résidus combustibles en pourcentage de l'approvisionnement total à l'entrée, et le rapport estime également le coût de triage par tonne métrique verte.

Abstract
With the appropriate mainline attachment, chain chokers are a viable alternative to conventional wire rope chokers, particularly for small-scale operations. This report provides users of tractor-mounted winches and cable skidders with technical information on chain chokers. The report covers type of steels, chain specifications and grades, and how to inspect chains for wear elongation. The various components (e.g. sliding hooks, rings) used to assemble chain chokers are also discussed.

Abstract
Pacific Forest Products Limited began commercially thinning Douglas-fir dominated second-growth forest on southeastern Vancouver Island with mechanized shortwood systems in 1992. In the summer of 1994, FERIC monitored a thinning operation near Cowichan Lake to determine productivities, costs and impacts to sites and residual stands. The thinning treatment was carried out with a Timberjack 1270 harvester and a Timberjack 910 forwarder.

Abstract
Durant l'année 1995, FERIC a effectué des études de productivité dans des opérations de récupération de chablis dans la région de Charlevoix au Québec et des Christmas Mountains au Nouveau-Brunswick. Les objectifs de ces études étaient d'évaluer quel était le système de récolte le plus efficace dans ces opérations, de définir les meilleures techniques de travail et de mettre en lumière les effets relatifs de la récupération de chablis sur le productivité.

Abstract
This report provides detailed estimates of current delivered roundwood costs for lumber and pulp, as well as the costs of forest biomass harvested in a system integrated with the roundwood harvest. Three different harvesting systems were studied: full-tree to roadside, integrated cut-to-length and full-tree chipping, and cut-to-length. Two typical site types were used: a boreal softwood site and an Acadian mixedwood site. Results are presented in $/m3 and in $/gmt (green metric tonne) for both roundwood and forest biomass. The effects of haul distance, biomass moisture content and the utilization rate of the biomass production machines on total cost are analyzed. Other factors that affect the viability of forest biomass as an economic source of energy are discussed.

Abstract
The Mountain Alternative Silvicultural Systems (MASS) study is a multi-disciplinary, multi-agency project initiated both for silvicultural and social reasons. MacMillan Bloedel Limited, the Canadian Forest Service, and FERIC cooperated in the study, with participation by the University of Victoria and the University of British Columbia. Three alternative treatments representing a range of canopy removal levels - uniform shelterwood, green tree retention, and patch cutting - were implemented in the research area, located on the east coast of Vancouver Island. FERIC monitored the productivity and cost of the falling and forwarding operations, and measured site disturbance and coarse woody debris for each harvesting treatment. The results of FERIC's study are presented.
