Abstract
In 2020, Alberta Agriculture and Forestry’s (AAF) Wildfire Management Branch contracted two externally tanked heavy helicopters with on-board injection and mixing systems. The two heavy helicopters are Sikorsky S-61N helicopters with modified Isolair tanks, capable of dropping water, foam, and water-enhancers. Drop tests were conducted using these helicopters to understand the relative footprints of different suppressants. This study focuses on using drop footprint data to estimate recovery rates of water, foam, and water-enhancers in two scenarios – an open field and a forested stand. These estimates may provide a primarily understanding of how best different suppressants can be used for different applications.

Abstract
Les forêts aff ectées par des épidémies d’insectes, en l’occurrence par la TBE, présentent une structure de peuplement hétérogène. Cela s’explique, entre autres, par le niveau de défoliation qui n’est pas nécessairement le même d’un arbre à l’autre. La récolte de ces peuplements engendre des coûts supplémentaires. Ceux-ci sont occasionnés par une perte de productivité des machines associée au temps supplémentaire requis pour produire un panier de produits répondant aux spécifi cations des usines. Par ailleurs, les récents développements en télédétection ont montré un grand potentiel pour réaliser des cartes précises et détaillées pouvant améliorer le processus de planifi cation et le déploiement d’opérations forestières. C’est dans ce contexte que des études ont été menées depuis 2014 sur la Côte-Nord. Elles ont permis de mesurer les pertes de productivité des machines et de développer une cartographie plus fi ne permettant de guider les opérateurs vers les endroits où la valeur des tiges assure la viabilité des opérations.

Abstract
A biomass heat map is a tool to help visualize the cost of biomass that is residual from harvest operations. The heat map is important because it can inform decision-making and economic feasibility studies. Its visual impact can trigger new thoughts and innovations in the human mind that a table of numbers can not... like: Where might we build a new plant? Should we compete at an existing delivery point, or not?

Abstract
n collaboration avec l’Université de Victoria, on a mis au point un mur de cisaillement à haute capacité comportant deux rangées de clous au périmètre du revêtement. On a mené un programme d’essais pour évaluer la performance du mur de cisaillement proposé, ce qui comprend la résistance aux charges latérales et aux déplacements, le comportement hystérétique, la rigidité et la ductilité.

Abstract
The widespread availability of genomics data and molecular tools for pathogen detection and identification provides scientists and regulators a powerful toolbox for pathogen monitoring. However, this raises questions and concerns regarding the use of these tools in import and export of forest commodities. Discussions around implementation and standardization have highlighted knowledge gaps around their efficacy and suitability in wood and their applicability to forest commodities. This study compared detection efficacy of various emerging tools on artificially infected forest and wood commodities, focusing on Phytophthora pathogens, an important group of invasive and sometimes difficult to detect species. In situ detection was more sensitive than traditional isolation, and for some methods, 100% of infected samples were positive. Detection efficacy varied by tissue type and detection method. The data generated from this study is important in addressing knowledge gaps around pathogen detection in wood.
