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 sampled butt-damage on 25 interior felling operations. One hand- faller, 4 shear machines and 20 non-shear machines were sampled. Lumber trim losses (2 X 6-inch basis) to remove damage were predicted as a percentage of total lumber content in the tree. Predicted losses were highest for the shear machines, substantially lower for most non-shear machines and negligible for the hand-faller.

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.

Attirer, retenir et former la main-d’œuvre représentent des défis pour les opérations forestières d’Amérique du Nord. 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
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
This report is intended to be a follow-up to FERIC TN-58 "using circular saw felling heads to reduce butt splitting damage". In TR-56, shift-level production data have been collected and analysed for the Harricana and Koehring circular saw, the Denis SJ-24 twin saw, the Boreal DD-20 double-deck saw and the Lokomo cone saw felling heads. The five felling heads are compared side-by-side on various criteria such as carrier and hydraulic requirements their operational and mechanical aspects, butt splitting damage, smoothness of cut, stump height and kerf width.

Abstract
Despite the oscillations in the price of fuel at the pump, it continues to rise. Five years ago, fuel accounted for 30% of transportation costs. Today, that proportion is estimated to be at least 40%, and the forecasts are not optimistic. It is therefore crucial to look at the factors that can influence fuel consumption and and how to reduce it. The team of researchers from the Transportation and Energy program of FPInnovations program is working on this issue and is analyzing various possible solutions.
Abstract
Malgré les oscillations du prix du carburant à la pompe, ce dernier ne cesse d’augmenter. Il y a cinq ans, le carburant représentait 30% des coûts de transport. Aujourd’hui, cette proportion est estimée à au moins 40 %, et les prévisions ne sont pas optimistes. Il est donc crucial de regarder les facteurs qui peuvent influencer la consommation de carburant et les moyens de la réduire. L’équipe de chercheurs du programme Transport et Énergie de FPInnovations travaille sur la question et analyse différentes pistes de solutions.
