Abstract
This review explores the benefits, challenges, limitations, logistics, and cost-effectiveness of different management options to convert conifer-dominated stands to aspen-dominated stands. These alternatives can include overstory removal (harvesting, bulldozing, shear blading, prescribed burning) and site preparation (root trenching, drag scarification, broadcast burning) treatments. On sites where parent aspen trees are not present in the original stand, tree planting will be necessary albeit costly in comparison to regeneration by suckering. While extensive literature exists on the regeneration of trembling aspen through suckering, research on artificial establishment with seedlings and its requirements is still in its infancy and rapidly developing.

Abstract
Hosted by Edouard Proust, this presentation by David Bevly held on February 10, 2021 highlights an important component of FPInnovations' Transportation and Infrastructure group's work. The concept of truck platooning, inspired by pelotons of cyclists and originally developed for highway use to obtain fuel savings, utilizes technology to maintain the desired distance between trucks by controlling acceleration and braking, and the relative lateral position of the vehicles by steering, reacting faster than a driver can. Truck platooning has attracted the attention of the natural resources sector and its implementation is expected to increase the productivity of drivers. By allowing the operation of driverless following trucks replicating the path set by the human operated leader vehicle, the concept could help mitigate the workforce shortage that impact the sector while supporting the supply of lumber to mills across the country.
Abstract
Ce contenu est exclusivement en anglais. Merci de contacter notre équipe si vous souhaitez obtenir de l’information en français. Cette présentation de David Bevly a été organisée le 10 février 2021 par Edouard Proust. Elle met en lumière une composante importante du travail effectué par le groupe Transports et Infrastructures de FPInnovations. Le concept d’opération de camions en peloton est inspiré des pelotons de cyclistes et a été mis au point à l’origine pour des applications autoroutières avec pour objectif une réduction de la consommation de carburant. Les camions sont équipés d’une technologie permettant le contrôle de l’accélération, du freinage et de la direction offrant la possibilité de maintenir la distance de suivi entre les véhicules ainsi que leur positionnement latéral relatif. En autorisant la mise en œuvre de camions suiveurs entièrement autonomes et qui répliquent le tracé du camion de tête opéré par un chauffeur, le concept pourrait à terme aider à minimiser l’impact du manque de chauffeurs dans l’industrie tout en supportant l’approvisionnement en fibre des scieries à travers le Canada.

Abstract
The clean air initiative led by the British Columbia Ministry of Environment seeks to develop innovative methods to improve community air quality by utilizing harvest residues and minimizing the volume of fibre burned at roadside. Retaining processed tops as roadside oriented piles is proposed as an alternative to burning debris. These burn trials have demonstrated that in this unique arrangement of fuels and interaction of site-specific variables, particular areas of the piles will be more vulnerable to ignition sources which can lead to sustained burning and high intensity fire behaviour. In addition to the low fuel moisture conditions, other fuel properties, such as the close proximity of piles, high volume of fine fuels (branches and needles) and orientation of piles to road all contributed to enhanced burning at this site.

Abstract
FPInnovations’ Wildfire Operations Advisory group has asked its researchers to explore a method by which the performance of water-enhancing products can be repeatedly assessed in the laboratory. A new test method, known as the crib test, was designed to evaluate the effectiveness of water-enhancing products on burning woody fuel to simulate direct-attack aerial operations. This report outlines the methodology for the crib test and describes the findings from performance evaluation tests conducted at the Protective Clothing and Equipment Research Facility (PCERF) at the University of Alberta.

Abstract
The USDA Forest Service’s Qualified Product List (QPL) provides guidance on the range of permissible mix ratios for water-enhancer products. Due to the proprietary nature of water-enhancer products, there are several unknowns about the rheology of the permissible mix ratios. This study focused on mapping the viscosity of various suppressant products as a function of their mix ratios. The results revealed a wide range of viscosities across products, with each product showing a different non-linear relationship with different mix ratios. The results from this study can help understand the optimum viscosity range to achieve desired drop characteristics during aerial operations.

Abstract
FPInnovations investigated the possibility of collecting real time temperature-altitude data that could be used to determine the stability of the atmosphere. Unstable atmospheric conditions have been associated with erratic and extreme fire behaviour. An increased awareness of atmospheric stability conditions would provide fire managers an additional tool to plan firefighting activities. A firefighting aircraft with a specific sensor was sourced and two years of data was collected and analysed to determine if temperature profiles could be built using the data. Results show the data was sufficiently accurate and was collected at a frequency where temperature lapse rates can be calculated, and the stability of the atmosphere in the area of a fire could be determined.

Abstract
Hemlock can have higher moisture content than most other native trees, causing them to sink. Hemlock lumens have large pits (valves) that allow easy transport of water into the wood. Bigger rings = bigger lumens. Younger hemlock or hemlock tops are more susceptible to sinking. The bigger the rings the more likely to take on water.

Abstract
This study tested ultra-high molecular weight polyethylene (UHMWPE) ropes for log load securement. Destructive testing of used rope samples done in a previous project found that the strength of these ropes decreased with use. To address this problem, the diameter of the synthetic rope was increased. In addition, a different type of rope with a UHMWPE inner core covered with a polyester protective jacket was tested. The outer jacket protected the inner core from dirt and abrasion which may help mitigate the loss in strength that occurs with use. Wrappers were put into service and tested for breakage after three and six months of use.

Cette étude a évalué des câbles en polyéthylène de poids moléculaire ultra élevé (PEPMUE) pour sécuriser des chargements de billes. Des tests destructifs d'échantillons de câbles usagés effectués dans un projet précédent avaient révélé que la résistance de ces câbles diminuait avec l'utilisation. Pour résoudre ce problème, le diamètre du câble synthétique a été augmenté. De plus, un autre type de câble avec une âme intérieure en PEPMUE recouverte d'une gaine de protection en polyester a été testé. La gaine extérieure protégeait le câble intérieur de la saleté et de l'abrasion, ce qui peut aider à atténuer la perte de résistance qui se produit avec l'utilisation. Les câbles ont été mis en service et testés pour la résistance à la rupture après trois et six mois d'utilisation.
