Abstract
Green finger jointing is increasingly becoming a proven possibity with three main technological processes, the New Zealand Greenweld process, the US soybean-based adhesive process and the US soybean-based adhesive process by assessing drying degrade and mechanical performance of green-glued finger-jointed material after drying. The urethane-based adhesive process was studied in a previous project. Overall, we did not observe performance differences between the Greenweld and the soybean-based adhesive processes. This was to be expected since they are both phenol resorcinol formaldehyde types of adhesives. Thus, the process choice should be made based on other considerations than mechanical performance, such as economical or procedure preferences. In comparison with the polyurethane adhesive studied before, it appears obvious that more stress concentration is present at the joint after drying because of the failure modes observed. However, with long term use, this product (the urethane-based adhesive) still needs to be studied because it is less known than the two other phenol-resorcinol-formaldehyde based processes. The results also demonstrate that green finger-jointing material, such as black spruce and balsam fir, could at least be used to produce stud grade lumber.

Abstract
The City of Quesnel, B.C. has applied an innovative selective harvesting technique in a mature Douglas-fir forest stand with the objectives of maintaining biodiversity and reducing fuel-load buildup and consequent wildfire threat. FPInnovations researchers monitored and documented the harvesting operations and measured machine productivity to evaluate the cost-effectiveness of the operation. To support the assessment of fuel-load reduction, FPInnovations’ Wildfire Operations group conducted pre- and post-harvest fuel-sampling activities to evaluate changes in forest fuel components.
