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.
A study by the British Columbia Ministry of Forests (BCMOF), Fraser Lake Sawmills (of West Fraser Mills Ltd.), and the Forest Engineering Research Institute of Canada (FERIC) compared at-the-stump and roadside processing of stems. FERIC determined the productivity and costs of the two harvesting systems and five subsequent regeneration regimes. The impacts of these treatments on slash distribution, cone distribution, mineral soil exposure, site distrubance, and plantable spots were also examined.
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.
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.
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.
Canadian Forest Service researchers are working to estimate forest productivity at different spatial scales. Variations in productivity are best appreciated at the tree and stand level in productivity.
Les chercheurs du Service canadien des forêts travaillent à estimer la productivité forestière à différentes échelles spatiales. C’est à l’échelle de l’arbre et du peuplement que s’apprécient le mieux les variations dans la productivité.
