Abstract
FPInnovations conducted a ground-based ash and biosolids spreading trial in Quebec. One treatment used a horizontal spinner as a spreading method and the other treatment used a line-dumping method. The trial showed that deflector plates helped to increase spreading uniformity. The trial results were also used to create a costing model that calculates productivity and the costs of spreading ash or biosolids using the two application methods.

Abstract
There is uncertainty regarding the effectiveness of using caulk boots vs. non-caulk hiking boots in silviculture work in the interior of British Columbia. WorkSafeBC regulation 8.23, states “caulked or other equally effective footwear must be worn by workers who are required to walk on logs, poles, pilings or other round timbers”, but does not specifically require caulk boots to be worn on steep slopes. Caulk boots are used almost exclusively by silviculture workers in coastal B.C. but are not commonly used in interior B.C. even though there are many situations where they may provide superior traction. Instead, workers in interior B.C. have a preference for non-caulk hiking boots. Workers will often select their boots based on personal preference rather than on information about the boot’s traction performance. Additional information regarding the differences in the traction of caulk boots and non-caulk hiking boots on various forest ground surfaces would help most workers make better-informed choices. Understanding the differences in traction is one of the most important factors when selecting a work boot in any situation and is especially true in the hazardous ground conditions of forest workers. For this reason, FPInnovations constructed a testing apparatus designed to measure and compare the static coefficient of friction of caulk boots and non-caulk hiking boots on four common types of ground cover surfaces in B.C. forests.

Abstract
FPInnovations studied a series of four partial harvesting trials and one combined partial harvesting–clearcut trial over three years in the Prince George (B.C.) Forest District. The partial harvesting trials harvested pine trees killed by the mountain pine beetle while protecting the non-pine secondary structure. The purpose of protecting the secondary structure is to provide a viable stand that will enhance the mid-term timber supply in 15 to 50 years. This report provides the costs, productivity, and harvesting damage results of the partial harvesting and clearcutting treatments used in the fifth and final trial. The pre-harvest stand was stocked with non-pine trees before harvesting, but was not stocked following the partial harvesting treatment. Slightly more than one-third of the net block area was clearcut for roads, trails, and landings. The trial results suggest up to 23% of the harvested non-pine overstory could potentially have been protected.

Abstract
In this FPInnovations–Feric Division project, we studied a series of partial harvesting trials in which the objective was to harvest all the pine trees while protecting the secondary structure in stands infested by the mountain pine beetle. The purpose of this type of treatment is to salvage the present value of the beetle-killed pine while preserving the existing secondary structure to provide a viable stand by the mid-term timber supply period (15 to 50 years from now). In this report, we provide the results from four trials in the Prince George (B.C.) Forest District using four different ground-based partial harvesting methods: a motor-manual (chainsaw) cut-to-length (CTL) method, a mechanized CTL method, a motor-manual full-tree method, and a mechanized full-tree method. Variations in pre-harvest stand attributes, harvesting equipment, and methodology resulted in differences in the total trail area, harvesting costs, and amount of secondary structure remaining undamaged in the residual stands. The results indicate that with an appropriate harvesting method and sufficient secondary structure present in the pre-harvest stand, it should be possible to harvest the mature pine trees and provide stands that will produce acceptable volumes of timber in the mid-term time period.

Abstract
FPInnovations conducted a Mechanical Site Preparation trial with a Lamtrac 8290Q mulcher near Okanagan Falls, B.C. The mulcher was tested on three sites: moderate slope with heavy grass competition; moderate slope with high stumps and moderate to high slash levels; and steep slope with low to moderate slash levels. The Lamtrac mulcher had some difficulty with heavier slash loads, but was able to create acceptable microsites at the target density of 1000–1200 microsites/ha under the three different site conditions.

Abstract
Extremely high density lodgepole pine stands in the Kootenay Region were thinned with mechanized narrow-strip treatments. This trial designed and implemented a sampling protocol to monitor the treatment over time. The initial tree measurements were recorded to provide the foundation to compare the growth and yield and assess the potential for meeting long-term objectives for stand density.

Abstract
Ce guide vise à répondre aux questions des gestionnaires de terres qui envisagent de recourir à l'épandage de cendre en forêt au Canada. Bien que les détails liés à la mise en place d'un programme d'épandage ne soient pas abordés dans le présent guide, ce dernier aidera les gestionnaires à comprendre les raisons associées à l'utilisation de cendre à titre d'amendement du sol et la portée du développement d'un programme d'épandage propre à leur région. Ce guide contient aussi un aperçu de la législation pertinente.

Abstract
This study focused on the energy intensity of four loaders loading and unloading logging trucks in a Northern Alberta forest operation. The study also measured the productivity and fuel consumption of one loader at two reduced engine RPM settings in order to determine the optimum machine setting for lower energy intensity.
