Abstract
Debris piles were scattered among a fuel-treated stand at the Jumpingpound Demonstration Forest. The existing trees were deemed as assets worth protecting while the piles required to be burned. To facilitate the protection of the trees surrounding these debris piles, the Calgary Forest Area requested the use of water-enhancer capable fire engines to protect the trees during debris pile burning.
A total of 15 debris piles of varying fuel loads were burned over two days. The use of water-enhancer capable fire engines allowed FPInnovations to document the use of suppressants (water and water-enhancer) to better understand their advantages and limitations. Qualitative observations suggested that water-enhancers were more effective at withstanding radiant heat than water when applied immediately prior to the incident heat. Its efficacy, however, was found to decline with time.

Abstract
Multiple log-deck fires at mill sites and log yards in Western Canada in the past year resulted in the loss of merchantable timber. These fires showcased how existing equipment and suppression efforts from wildfire agencies are heavily challenged when asked to handle the thermal output from burning log-decks.
In an effort to explore alternate solutions, FPInnovations collaborated with West Fraser and the High Level Forest Management Area to understand the efficacy of high-volume water delivery systems in log-deck fire suppression. Over the course of three days, water-penetration tests as well as suppression tests were carried out to better understand the utility and resource requirements of high-volume water delivery systems.

Abstract
Forest fuel reductions treatments are conducted at a stand level in the wildland–urban interface to reduce the potential for catastrophic loss caused by wildfire. Given the considerable expense of conducting these fuel treatments, fuels managers want to better understand the productivity and cost of commonly applied fuel treatments in order to prescribe cost-effective treatment techniques. Due to the limited data available and the myriad combinations of fuel treatment options and equipment types used in a diverse range of ecosystems, cost projections for fuel treatments are difficult to forecast reliably.
This document provides background on and fundamental principles of productivity studies, and a summary of motor-manual productivity studies that have been conducted in timber silviculture operations, forest fuel reduction treatments, and other manual forestry operations.

Abstract
Disposal of woody debris and vegetative matter from forest fuel reduction treatments is a challenge and alternatives to conventional methods of pile burning and chipping are being considered. The construction of hugels is proposed as a debris management technique that would configure debris on site in a less flammable state. Flammability of piled debris (hugels) and the productivity of hugel construction are key considerations in assessing the viability of this debris disposal method.
Another consideration in assessing hügelkultur as a long-term debris management strategy is the decomposition of hugels and the evolving flammability of hugels. Research literature does not speak directly to the changing flammability of piled debris (and more specifically hugels), but this literature search attempts to locate material relevant to decomposition of woody debris in a hugelkultur environment.

While flammability of piled debris (hugels) is a key consideration in the viability of this debris disposal method, the cost of the operation must also be considered.
This research design presents the development of test methods and data collection methods that can be applied in evaluating the productivity of a fuel reduction treatment that incorporates construction of hugels as a debris management tool. Comparative productivity trials will evaluate these productivity results in relation to fuel treatments that apply conventional debris disposal methods.

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
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
Forest fuel treatments are applied across a broad range of ecosites in Alberta and Canada, with an overarching goal of managing hazardous fuel buildup to mitigate wildfire. These treatments use various manual and mechanical processes to achieve fuel treatment objectives. Planning and application of a specific forest fuel treatment technique is often shaped by several factors, including objectives of the fuel treatment, availability of resources (personnel and equipment), and commitment to using local resources (socio-economics). In addition, site conditions in certain ecosites will favour the application of some treatment techniques over others. With the broad nature of numerous fuel treatment techniques applied over a wide range of environmental conditions, it is difficult to document all treatments and develop comparative productivity and cost evaluations. This summary of fuel treatment studies accesses current research to present relevant findings and identify knowledge gaps in research on stand-level fuel treatment productivity.

Abstract
Modified oxygen consumption calorimetry was used to track the seasonal flammability of black spruce and tamarack. Age class related samples were collected for both species from May to September at research site in central Alberta. These samples were assessed for their differential heat release using test equipment at the Protective Clothing and Equipment Research Facility (PCERF) at the University of Alberta. The test method was able to successfully quantify the differences in seasonal flammability between black spruce and tamarack. Data showed the age-related flammability differences were less pronounced, with the exception of new growth samples early in the season.
