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.
The management of resource road network infrastructure such as roads, bridges, culverts in a cost-effective manner while ensuring that the required performance needs are met can be a challenge. This report introduces the key concepts of asset management and provides an overview of many of the key factors to implementing a successful asset management plan.
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.
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.
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.
In 2009, FPInnovations created a spreadsheet tool based on a culvert length field guide originally developed by Dominico Iannidinardo of Timber West Forest Corp. The FPInnovations’ culvert length estimation tool was developed to assist with estimating culvert barrel length requirements for cross drains and for stream crossings. The tool also provided expert comments on culvert and road cross-section geometry.
In 2014/15, with support from BC Timber Sales, upgrades were made to the culvert length estimation tool. These changes expanded the scope of the tool to include some important design considerations not in the original tool. The upgrades include a function that helps optimize culvert ordering from suppliers, expert comments on fish passage and coupler selection, and determination of appropriate culvert material type and wall thickness. The software is available for download at the FPInnovations website www.fpinnovations.ca
The B.C. coastal forest industry relies heavily on water transport for the movement of logs. Logs are traditionally made into bundle booms or loaded onto barges and are towed by tug boats to sort yards or docks, or to mills for processing. This method of transport has been preferred due to its cost-effectiveness, given the unique and challenging terrain of the coast. However, by transporting logs in water, additional cost is incurred in the mill due to corrosion of equipment from salt water. Further, it is more challenging to find uses for, and to dispose of, salt-laden mill residuals, such as hog fuel.
Previous work done by FPInnovations compared different modes of log transport: truck, boom, and small and large barge on a hypothetical trip from Campbell River to Nanaimo. The study found that when both direct and indirect costs are included, transporting logs by small barge and keeping them out of salt water is the most economical means of transport. Operations south of Cape Caution, which is on the east side of Vancouver Island, and the west coast of mainland B.C., could potentially replace log booms with small barges, should it be more economical to do so. The original report compared truck transport to water transport. The current report will solely focus on comparing the costs and operational implications of switching from log booms to small barges.
Several thousand hectares of non-commercial softwood forests are thinned each year in Eastern Canada. Although this intervention is justified by the logic of reducing competition between stems, thus competition between stems, thus favouring the growth of residual trees, few studies with quantitative data on the long-term effects of thinning of precommercial thinning (PCT) are available. How does this treatment actually influence tree growth? What are the long-term impacts on fiber quality and quality and value of the fiber?
Plusieurs milliers d’hectares de forêts résineuses non commerciales sont éclaircis chaque année dans l’Est du Canada. Bien que cette intervention soit justifiée par la logique de diminuer la compétition entre les tiges, favorisant ainsi la croissance des arbres résiduels, peu d’études comportant des données quantitatives sur les effets à long terme de l’éclaircie précommerciale (EPC) sont disponibles. Comment ce traitement influence-t-il réellement la croissance des arbres? Quelles sont les incidences à long terme sur la qualité et la valeur de la fibre ?
