Abstract
Harvesting with 33-m trail spacing was proposed by FERIC as a way to meet the quality criteria for single-tree selection in hardwood forests in Quebec's public forests. The approach is, however, applicable to any partial-cutting treatment in hardwood forests, and the method was studied in 16 operations in 2003-2004. The approach represents an acceptable compromise between protection of the residual stand and operating costs, as the productivity of the feller-bunchers using this method decreased only slightly as a result of increased travel. The operations that FERIC studied did not all meet the target quality criteria, but provided an adequate level of protection of residual stems. The method requires a certain degree of control to limit the felling of non-marked stems, and the use of evaluation criteria specially adapted to this method would facilitate its implementation.

Abstract
Biomass sampling and analysis play decisive roles in determining the characteristics and value of the woody biomass fuel used in bioenergy systems in Canada. Sampling and analysis standards help harmonize the procedures that are used to monitor biomass quality. Because there are no Canada- wide biomass sampling standards, facilities that produce and use woody biomass have developed and implemented in-house sampling procedures of varying degrees of complexity. Given that the use of woody biomass in Canada is predicted to increase, the ability to ensure the quality of biomass will become increasingly important in order to control costs and maximize system efficiency.

Abstract
L’échantillonnage et l’analyse de la biomasse jouent un rôle décisif dans la détermination des caractéristiques et de la valeur des combustibles de biomasse ligneuse utilisés dans les systèmes de bioénergie au Canada. Les normes d’échantillonnage et d’analyse contribuent à harmoniser les méthodes utilisées pour évaluer la qualité de la biomasse. Il n’existe pas de normes d’échantillonnage pancanadiennes; les usines qui produisent ou utilisent la biomasse ligneuse ont donc élaboré et appliqué des méthodes d’échantillonnage maison de niveau de complexité variable. Comme on prévoit une augmentation de l’utilisation de la biomasse ligneuse au Canada, les compétences permettant de garantir sa qualité deviendront de plus en plus importantes pour limiter les coûts et maximiser l’efficacité des systèmes.

Abstract
This report documents the costs and productivities of group-selection harvesting of one-third of a stand in an old-growth cedar–hemlock forest in the interior wet-belt of British Columbia while preserving caribou habitat values. The group-selection harvesting was compared to clearcut and single-tree selection treatments. Harvesting costs were strongly influenced by the merchantability of the harvested stems and the criteria for selecting trees to be harvested. The single-tree selection had the lowest cost because of the selection criteria and merchantability while the group selection had the highest cost. The group selection treatment’s harvesting costs were about 22% greater than for the clearcut treatment.

Abstract
Evaluation  of  forest  environments  to  assess  fuel  loading  using  conventional  inventory methods is labour-intensive, time-consuming, and requires extensive training to be completed correctly. Fuels managers would like to apply simpler, less expensive fuel sampling methods and still maintain acceptable accuracy in fuel load measurements. FPInnovations  has  explored  different  fuel  sampling  techniques  that  may  be  applicable to the forest stands of central British Columbia. The photoload sampling technique  was  deemed  to  be  a  valuable  tool  that  can  be  enhanced  to  suitably  represent the forest fuels in Interior Douglas-fir environments and can be adapted to other fuel environments with appropriate amendments.

Le présent rapport décrit divers outils statistiques de CQ et en fait la démonstration à l’aide d’exemples de données sur le taux d’humidité de la biomasse. Ces outils peuvent être développés à l’interne ou achetés, mais il est recommandé de les intégrer aux bases de données actuelles (p. ex., LIMS). Les experts de FPInnovations peuvent aider à établir un programme de CQ adapté à une entreprise ou à un produit de biomasse et former les équipes de CQ en vue du développement et de l’utilisation des outils présentés ici.

Abstract
To support the implementation of biomass procurement practices, a formal, rigorous, consistent, science-based biomass quality control (QC) program is needed. This program should be designed to determine customer needs, the sources of product variation, and ways of eliminating or minimizing product variation as soon as it occurs. The program should also include a well-designed QC plan and sampling protocol, statistical process control methodologies and tools, formal QC teams, and regular training. This report describes various statistical QC tools and demonstrates those using examples of biomass moisture content data. These tools can be developed in-house or be purchased, but their integration with existing databases (e.g., LIMS) is recommended. FPInnovations experts can assist in developing customized QC programs for companies and for specific biomass products, and can train QC teams to develop and use the tools presented here.

Abstract
In 1992 the Forest Engineering Research Institute of Canada (FERIC) studied a heavy-lift helicopter logging operation on the Queen Charlotte Islands in British Columbia. The study was part of a Fish-Forestry Interaction Program project to investigate the feasibility of using alternative harvesting and silvicultural systems to harvest timber from potentially unstable terrain. The study provided information on the productivities and costs of helicopter logging in clearcuts, patch cuts, and single-tree selection cuts, using a Sikorsky S-64 Skycrane equipped for choker logging. Information on basal area removal levels, damage to residual stems, and ground disturbance was also collected. Production and cost functions were derived from detailed-timing and shift-level data to predict helicopter yarding productivity and cost by harvesting treatment for yarding distances of 100 to 1 500 m.

Abstract
One of the challenges to the use of biomass in heat applications is to find a suitable technology to take quick and accurate moisture content (MC) measurements of comminuted forest biomass. In this study, we tested three difference technologies (electric, nuclear and infrared) and five different tools. Of the three technologies tested, electric is the most promising. It is usually inexpensive (<$1000), requires small-sized samples (10 L), is fast to read (<1 minute) and is relatively accurate with more than 70% of measurements within 5% MC of the oven-dried method.

Abstract
L’une des difficultés associées à l’utilisation de la biomasse forestière broyée pour produire de la chaleur consiste à trouver une technologie convenable pour prendre rapidement des mesures précises de la teneur en humidité (TH). Pour la présente étude, nous avons mis à l’essai trois technologies (électrique, nucléaire et infrarouge) et cinq appareils différents. Parmi les trois technologies, c’est la technologie électrique qui est la plus prometteuse. Les appareils sont généralement peu coûteux (< 1000 $), nécessitent des échantillons de petite taille (10 L), donnent les résultats rapidement (<1 minute) et sont relativement précis, plus de 70 % des mesures se situant à plus ou moins 5 % de la TH obtenue par la méthode de séchage à l’étude.
