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.
Au Canada, on prévoit que les changements climatiques auront une incidence considérable sur l'industrie forestière. Les routes d'accès sont particulièrement vulnérables aux effets immédiats et à court terme des changements climatiques. Des stratégies d'adaptation pour les routes d'accès et les infrastructures doivent être élaborées et leur mise en œuvre doit commencer, afin de s'assurer que les infrastructures routières nécessaires pour accéder à la forêt soient maintenues et résistent aux effets des changements climatiques. Ce rapport présente les risques et la vulnérabilité des routes d'accès aux changements climatiques, ainsi que des méthodes et pratiques recommandées pour s'y adapter.
The changes to climatic conditions in Canada are anticipated to have a significant impact on the Canadian forest industry. Resource roads are considered particularly vulnerable to the immediate and short-term impacts of climate change. Adaptation strategies for resource roads and infrastructure must be developed and implementation initiated to ensure that the road infrastructure required for forest access is maintained and made resilient to climatic impacts. This report presents the risks and vulnerabilities of resource roads to climate change and suggested adaptation methods and practices.
FLNRO, with technical assistance from the B.C. Ministry of Transportation and Infrastructure and FPInnovations, conducted a case study of the vulnerability to climate change of infrastructure on the 70 km-long in-SHUCK-ch forest service road. The workshop participants followed a process established by the Public Infrastructure Engineering Vulnerability Committee (PIEVC). This case study provided both meaningful analysis of the risks and opportunities faced by the in-SHUCK-ch FSR corridor and the communities it provides access to, and establishes a benchmark for future iterations of the process with resource roads.
A series of recommendations are made that arise from the PIEVC analysis. These recommendations included the need to streamline and focus the PIEVC process specifically for resource roads, capacity building actions by road managers and maintainers, a review of emergency preparedness plans for the communities accessed by the FSR, actions to safeguard FSR infrastructure and residential development on lakeshore debris fans, a general review and inspection of drainage structures, actions to review and improve the resiliency of stream crossing structures and, finally, a recommendation to review the scope and size of the road maintenance program.
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.
FPInnovations, in cooperation with Alberta Transportation and the Laval University i3C Chair, undertook a review of the starting threshold for initiating winter weight hauling in Alberta. The objective of this project was to conduct an engineering analysis of freezing pavements to determine the minimum frost depth at which log hauling at winter weight premiums (WWP) in Alberta could start without compromising pavement service life. The report describes literature on freezing pavement engineering, Canadian winter weight policies, a controlled trafficking simulation of an instrumented pavement as it was frozen, and subsequent modeling to valiidate results and extrapolate results ot a wider range of pavement structures. It was recommended that the current 1.0 m starting frost depth threshold be reduced to a depth of 700 mm.
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.
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.
Debris management at logging sites and handling facilities is of increasing concern due to the volume of accumulated material and the constrained options for disposal. In March 2014, B.C. Timber Sales (BCTS) provided a timber sale on Maurelle Island that produced a large quantity of detached bark which originated from a 132-ha harvest area. Harvesting was during March 2014, and the predominant source of bark was from 41 150 m3 of Douglas-fir which accounted for approximately half the harvested volume (88 050 m3 total harvest volume). The bark accumulated at both a log storage area and on a transport barge during loading and unloading. The bark was disposed of along two dead-end spur roads (Figure 1). One of the spur roads has a small S6 stream (non-fish bearing) crossing through it. The disposal of logging debris (bark) along spur roads had not been considered or tried before by the Strait of Georgia Business Area of BCTS. The bark for Douglas-fir accounts for 30% by volume, which is the highest overall volume of bark for all softwood species (on average bark accounts for 10 to 15%).
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.
