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
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
Building high energy efficiency has become a must to reduce carbon emission from the built environment and to meet needs of consumers. Industrialized construction provides an effective way to produce highly insulated and airtight building envelopes to achieve superior building performance, such as Net Zero Energy. However, it is important that as other attributes (e.g., seismic, wind, fire, vibration, etc.) are being addressed, further research is needed to develop well rounded building envelope solutions. Meanwhile, improvement may be made in automated production equipment and software to optimize and monetize these solutions.

Abstract
Il est devenu indispensable de construire des bâtiments à haute efficacité énergétique pour réduire les émissions de carbone dans l’environnement et répondre aux besoins des consommateurs. La construction industrialisée est un bon moyen de produire des enveloppes de bâtiment bien isolées et étanches à l’air et, par le fait même, d’accroître la performance énergétique des bâtiments (p. ex consommation énergétique nette zéro). Cependant, il est important de tenir compte d’autres attributs (p. ex. charges sismiques, vent, feu, vibrations, etc.). Il faudra poursuivre les recherches pour trouver des solutions durables en matière d’enveloppes de bâtiment. Entre-temps, il est possible d’améliorer l’équipement de production automatisée et le logiciel qui l’accompagne afin d’optimiser et de rentabiliser ces solutions.

Abstract
This new study aims to generate hygrothermal, particularly moisture-related performance data for light wood-frame walls meeting the R22 effective (RSI 3.85) requirement for buildings up to six storeys in the City of Vancouver. The overarching goal is to identify and develop durable exterior wood-frame walls to assist in the design and construction of energy efficient buildings across the country. Twelve test wall panels in six types of wall assemblies are assessed in this study. The wall panels, each measuring 4 ft. (1200 mm) wide and 8 ft. (2400 mm) tall, form portions of the exterior walls of a test hut located in the rear yard of FPInnovations’ Vancouver laboratory. This report, second in a series on this study, documents the performance of these wall assemblies based on the data collected over 19 months’ period from October 2018 to May 2020, covering two winter seasons and one summer.

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
The fire resistance of cross-laminated timber (CLT) could be improved by treating the lamina with fire retardants. The major issues with this technology are the reduced bondability of the treated lamina with commercial adhesives. This study assessed several surface preparation methods that could improve the bondability and bond durability of fire-retardant treated wood  with  two  commercial  adhesives.  Four  surface  preparation  methods,  including  moisture/heat/pressure, surface planing, surface chemical treatment, and surface plasma treatment were assessed for their impact on the bondability and bond durability of lodgepole pine lamina. The block shear test results indicated that all surface preparation methods were somewhat  effective  in  improving  bond  performance  of  fire-retardant  treated  wood  compared to the untreated control wood samples, depending on the types of fire retardants and wood adhesives applied in the treatment process and bonding process. The selection of surface preparation, fire retardant, and wood adhesive should be considered interactively to obtain the best bond properties and fire performance. It may be possible to effectively bond the treated lamina with PUR adhesive without any additional surface preparation for the fire retardant used in the treatment at FPInnovations.

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.

Mechanized ground-based direct seeding was assessed in a variety of conditions to explore viability, determine which factors influence success, and determine the expected establishment rate when seeding with B.C. tree species. This report includes guidelines and recommendations for implementing direct seeding in B.C., based on observations from operational trials established in 2013-2017 across the province.

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.
