Abstract
Forest companies across Canada are interested in using laser scanners for scaling logs because it has potential for reducing scaling costs. Scanning logs over bark requires a method to obtain the under-bark diameter in order to calculate the solid wood volume. This report evaluates the methods of applying a bark factor to determine under-bark diameter. It also identifies new scanner scaling technologies for measuring bark thickness.

Abstract
FERIC a évalué un débardeur à câble équipé d’un treuil à double tambour et d’une radiocommande dans des opérations de coupe partielle de feuillus. L’augmentation de productivité a atteint jusqu’à 32 % selon la technologie utilisée, et la baisse de perturbation du terrain jusqu’à 40%. L’occupation par les sentiers et les dommages aux arbres résiduels ont également diminué (de jusqu’à 53 % et 79 %, respectivement). Les opérateurs montaient dans la machine beaucoup moins souvent, d’où une amélioration de la sécurité. Les télécommandes sont rentables pour toutes les machines, mais les treuils à double tambour coûtent probablement trop cher pour être installés sur de vieilles machines.

Abstract
FERIC assessed a cable skidder with a dual-drum winch and radio remote control in hardwood partial-cutting operations. Productivity increased by up to 32% depending on the technology used, and ground disturbance decreased by up to 40%. Trail occupancy and damage to residual trees also decreased (by up to 53% and 79%, respectively). Operators entered the machine significantly fewer times, thereby improving safety. Remote controls are cost-effective for any machine, but dual-drum winches are probably too costly to install on older machines.

Abstract
This study addressed biomass availability, harvesting, transportation, and chipping costs for the production of bioenergy in the Teslin region of Yukon. It revealed that significant volumes of standing timber below 20 cm in diameter at breast height (DBH) exist that could be utilized for bioenergy. These volumes, however, would sustain only small electricity generation capacities; however, a more efficient solution would be to utilize the biomass in district heating applications. The study also estimated harvesting, transportation, and chipping costs of low- and high-mechanized systems. These costs will have to be further validated and incorporated into an investment calculator to assess the feasibility of future bioenergy projects in Teslin.

Abstract
Attracting, retaining and training labor is a challenge for forest operations in North America. FPInnovations attended the Pacific Logging Congress (PLC) in November 2015 where one of the technical sessions focused on attracting and retaining people to the industry, in particular to contractor operations. The majority of the strategies presented in this Info-Note were suggested by logging contractors presenting at the PLC. A few others gleaned from other sources were added as well.

FPInnovations a assisté au Pacific Logging Congress (PLC) en novembre 2015, dont l’une des sessions portait sur les meilleures pratiques pour attirer et retenir les employés dans l’industrie, en particulier pour les entrepreneurs. La majorité des stratégies présentées ici ont été adoptées par les entrepreneurs forestiers qui faisaient une présentation au PLC. Nous en avons ajouté quelques autres obtenues d’ailleurs.

Abstract
The Forest Engineering Research Institute of Canada (FERIC) examined the level of butt damage from felling with high-speed circular saws in three winter harvesting operations in Alberta and British Columbia. The location and extent of the butt damage on each damaged stem were recorded, and the impact of the butt damage in terms of loss of sawlog volume available for lumber manufacturing was projected. Factors influencing butt damage are discussed, and recommendations to reduce wood losses are made.

Abstract
There is uncertainty regarding the effectiveness of using caulk boots vs. non-caulk hiking boots in silviculture work in the interior of British Columbia. WorkSafeBC regulation 8.23, states “caulked or other equally effective footwear must be worn by workers who are required to walk on logs, poles, pilings or other round timbers”, but does not specifically require caulk boots to be worn on steep slopes. Caulk boots are used almost exclusively by silviculture workers in coastal B.C. but are not commonly used in interior B.C. even though there are many situations where they may provide superior traction. Instead, workers in interior B.C. have a preference for non-caulk hiking boots. Workers will often select their boots based on personal preference rather than on information about the boot’s traction performance. Additional information regarding the differences in the traction of caulk boots and non-caulk hiking boots on various forest ground surfaces would help most workers make better-informed choices. Understanding the differences in traction is one of the most important factors when selecting a work boot in any situation and is especially true in the hazardous ground conditions of forest workers. For this reason, FPInnovations constructed a testing apparatus designed to measure and compare the static coefficient of friction of caulk boots and non-caulk hiking boots on four common types of ground cover surfaces in B.C. forests.

Abstract
The Forest Engineering Research Institute of Canada (FERIC) evaluated wood chip recovery and productivity at Weyerhaeuser Company Limited's pulp mill in Prince Albert, Saskatchewan. Frozen and unfrozen hardwood and softwood logs were debarked and shipped over a range of butt diameters and lengths. This report summarizes the chip recovery, quality, and productivity, and provides recommendations on how the operation and chip recovery can be improved.
