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
Le présent rapport donne des estimations détaillées des coûts actuels, à destination, des bois ronds de qualité sciage et de qualité pâte, de même que des coûts de la biomasse forestière récoltée dans un système intégré à la récolte des bois ronds. Trois systèmes différents ont été étudiés: la récolte par arbres entiers jusqu'en bordure de route, la récolte par bois tronçonnés intégrés au déchiquetage d'arbres entiers, et la récolte par bois tronçonnés. Les études ont eu lieu dans deux types de sites représentatifs:un site résineux boréal et un site mélangé acadien. Les résultats sont présentés en $/m3 et en $/tmv (tonne métrique verte) pour les bois ronds ainsi que pour la biomasse et du taux d'utilisation des machines produisant la biomasse sont analysés. D'autres facteurs qui affectent la viabilité de la biomasse forestière comme source économique d'énergie font l'objet d'une discussion.

Abstract
FERIC a étudié trois systèmes de récolte en coupe totale afin d'établir des productivités et des coûts spécifiques aux conditions de récolte en forêt mixte. Des systèmes mécanisés par arbres entiers et par bois tronçonnés ainsi qu'un système manuel ont fait l'objet d'observations en forêt mixte et les productivités obtenues ont été comparées aux productivités normalement rencontrées en forêt résineuse. Les trois systèmes ont donné des productivités moins élevées en forêt mixte qu'en forêt résineuse, à volume comparable par tige. Le coût total de récolte, incluant le coût de chargement, était plus élevé q'en forêt résineuse. Le système manuel est celui qui a subi la plus forte hausse de coût. L'abattage, l'ébranchage, le façonnage et le chargement ont été les activités touchées par la hausse de coût, pour un volume par tige et un nombre de tiges à l'hectare comparables. En réalité, le volume moyen par tige en forêt mixte est souvent supérieur à celui en forêt résineuse et le coût moyen de récolte devient alors comparable.

Abstract
This report presents a case study of the vulnerability to climate change of infrastructure on the Tum Tum Forest Service Road using the Public Infrastructure Engineering Vulnerability Committee (PIEVC) protocol. This case study provided analysis of the risks and opportunities faced by the road, recommendations to mitigate the identified risks, and established a benchmark for future iterations of the process with resource roads.

Abstract
This report summarises the work accomplished in this one-year project in which the fire performance of wood-frame buildings was to be documented. A detailed analysis of Canadian and American fire loss statistics for residential occupancies was undertaken in order to assess the impact of the choice of building materials and the nature of fire-safety provisions in building codes on the overall fire safety in buildings. It was expected that the knowledge gained would enable the wood industry to argue more effectively during deliberations of codes and standards committees. This study demonstrated that buildings constructed in compliance with current North American building code requirements are among the safest in the world. It was found that the fire loss record of wood-frame houses is about the same as that of large apartment buildings of non-combustible construction. It was shown that the ignition of upholstered furniture or mattresses by smokers’ materials is far and away the leading cause of residential fires involving deaths. Most of these deaths occur before the structure of the building becomes damaged by or involved in fire. Enacting more stringent building code requirements is unlikely to pay a large dividend in terms of life safety. In fact, the statistics suggest that significant improvements in fire safety in buildings would be more easily achieved by limiting the flammability of upholstered furniture and mattresses.

Abstract
FERIC studied three harvesting systems in clearcut operations to define their specific productivities and costs under the harvesting conditions typical of mixedwood forest; the systems comprised mechanized full-tree and cut-to-length systems, as well as manual system. FERIC compared their productivities with those typically observed in softwood stands and found that all three systems had lower productivities in mixedwood forest than in softwood forest at comparable stem volumes. The total harvesting cost, including the cost of loading, was higher than in softwood forest, and the manual system showed the greatest cost increase. Felling, delimbing, processing, and loading costs all increased for comparable volumes per stem and numbers of stems per hectare; however, since the average volume per stem is often greater in mixedwood forest than in softwood forest, the actual overall harvesting costs become comparable.

Abstract
The purpose of this study is to investigate and record the principal problems associated with chipped surface quality at canter lines and evaluate degrade and value losses due to these problems. Mill measurements were conducted in five member sawmills in British Columbia to evaluate the value losses and lumber degrades due to chipped surface defects. The test lumber was sampled from the planing mills to identify the chipping losses and main problems. The five types of chipped surface defects influencing lumber grade are: knot tear-out; failure to remove chipped spline channel; torn grain without knots; scalloping; and chipped thin end. Average value losses for all mills were $11.4/MBF and $12.6/MBF in freezing and non-freezing conditions respectively. Removing the non-freezing data from one mill changed this to $11.4/MBF and $9.0/MBF respectively. Knot tear out caused 60% of lumber to be degraded. On average, over 55% of knots had tear-out. 42.3% of trim length was caused by failure to remove chipped spline channel.

Abstract
Spontaneous combustion of hog piles can result in inventory losses and potential damage to surrounding infrastructure and equipment. In April and June 2016, FPInnovations and Terminal Forest Product Ltd. conducted a study to investigate the use of thermal infra-red digital cameras to examine the thermal dynamics of a coastal hog fuel pile. They also investigated the feasibility of using thermal imaging to help develop better fire risk mitigation solutions.
