FPInnovations prepared this guide to provide forest and resource workers with information on the planning and design considerations for streambed simulation in closed-bottom structures for fish streams. Other important considerations that are key to the successful implementation of a streambed simulation culvert include structure installation, streambed material, and monitoring. These subjects will be covered in future guides.
FPInnovations worked in close co-operation with British Columbia’s Fish Passage Technical Working Group in the development of this guide.
A primary goal of the Feedstocks project was to determine the volumes of forest, agricultural (short-rotation energy crops), and municipal solid waste feedstocks potentially available for a biorefinery in Nova Scotia. Based on existing local assets and other strategic factors, seven potential sites for establishing a biorefinery were identified across the province. It was then estimated what volumes of each feedstock would be available within 50, 100, 150, and 200 km of each site.
Utilizing forest harvest residue is an issue of growing urgency in the British Columbia forest industry, In B.C., forest residues at roadside have traditionally been burned to mitigate fire hazard or, occasionally, they have been left to rot. With an increasing demand for energy and concern over climate change and air quality, burning may no longer be the most desirable practice for dealing with residues. Further, there is an increasing demand for harvest residues by both primary and secondary users to fuel the growing bioeconomy in B.C.
This guide provides machine operators who work in winch-assisted harvesting operations with best practices guidelines for handling wire rope. It offers guidance on damage
prevention, inspections, end connectors, storage, and rope
management during harvesting operations. Following these
best practices is essential in order to maximize the service life
of the rope and to prevent accidents.

Au Canada, la majeure partie du transport forestier doit passer sur les routes publiques au cours de leurs cycles de travail et ces camions interagissent donc avec les usagers de la route et subissent les risques inhérents à la conduite dans une circulation plus dense. Les caméras de bord sont un outil de sécurité relativement nouveau.
Since 2000, all tractors and trailers manufactured in Canada are required to have anti-lock braking system (ABS).
It is difficult to keep these systems operational in off-highway applications such as log-hauling.
The most frequent issues with these systems involve wheel-speed sensors and wiring.
This guide provides a brief overview of these issues and recommends best practices for maintaining these systems.
Depuis 2000, tous les tracteurs et remorques fabriqués au Canada doivent être munis d'un système de freinage antiblocage (ABS).
Il est difficile de garder ces systèmes en fonction dans les applications ailleurs que sur les autoroutes, comme le transport de billes.
Parmi les problèmes les plus fréquemment éprouvés avec ces systèmes, on trouve les capteurs de vitesse des roues et le câblage.
Ce guide fournit un aperçu de ces problèmes et recommande des pratiques exemplaires pour l'entretien de ces systèmes.
Fuel is a major expense component of operating off-road machines, so finding ways to reduce machine fuel consumption can affect overall machine operating cost. FPInnovations measured the effect that a 5% change in grade had on the fuel consumption of a skidder, and also compared the fuel consumption of the skidder when its grapple carried the loads at various heights. Analysis of the test results allowed FPInnovations to recommend several fuel-saving practices that machine owners can utilize to optimize machine performance.
FPInnovations completed a trial in December 2016 which examined the productivity and cost of three methods of piling and grinding logging residues (Spencer and Blackburn, 2017). The December trial compared three pile types:
1. Piles built by a log loader for burning after the initial harvest.
2. Piles built by a log loader for biomass extraction after the initial harvest.
3. Piles built by the processor during the processing phase of harvesting.
One concern that arose from this trial was whether having a processor neatly pile residues created a loss in productivity versus the traditional method of throwing or “flinging” the residual tops as far as possible from the processor. Researchers returned to Vanderhoof in March 2017 to monitor the productivity of the two methods (throwing and stacking) for handling residues.
Wildfire is a natural phenomenon in Canada that threatens to destroy property and endanger lives. Wildfire agencies are tasked with reducing the threat of wildfire in the wildland-urban interface, which becomes a greater issue as more communities locate near or within forests or become more populated.
Forest fuel treatments that reduce or modify forest stands are the most common and effective methods to reduce wildfire danger around communities. However, convincing the public to support forest fuel treatments around their communities can be a challenge for wildfire managers. Understandably, communities want some assurance that what they are committing to will make a difference. One of the many benefits of forest fuel treatments is thought to be an increase in the effectiveness of wildfire operations.
Recent advances in ubiquitous sensing, such as accessible, wearable sensing technology and the emerging field of big data analytics have sparked the current wave of interest in self-tracking by means of personal wearable devices that quantify everyday activities and improve behaviours and processes. This trend is quickly extending into the workplace: It is estimated that by 2020, over 75 million wearable devices will be used in the workplace (Kaul and Wheelock, 2016). In this context, knowledge extracted from pervasive sensor data can lead to improvements in the health and productivity of workers and to gains in data-driven operational efficiency across a wide spectrum of sectors.
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%).
