Abstract
Le présent rapport fait la synthèse des travaux qui ont été réalisés à la demande du ministère des Ressources naturelles et de la Faune du Québec (MRNFQ) dans le cadre d’une mise à jour de leurs modèles économiques en forêt feuillue. L’étude visait à comparer la productivité de l’abattage mécanisé dans une coupe jardinatoire (CJ) avec la productivité des mêmes équipements et des mêmes opérateurs selon des modalités de coupe de régénération (CR). Les travaux ont permis de générer deux régressions illustrant la productivité de l’abattage mécanisé en fonction du volume moyen par tige pour chaque type de coupe en forêt feuillue et mixte.

Abstract
This report summarizes work that was performed at the request of Quebec’s Ministère des Ressources Naturelles et de la Faune (MRNFQ) as part of updating their economic models for hardwood forest. The study compared the productivity of mechanized felling in a selection cut with the productivity of the same equipment and operators working in a regeneration cut. This comparison generated regression equations for the productivity of mechanized felling as a function of mean stem volume for each type of cut in hardwood and mixed forests.

Abstract
The 1-2-3 shelterwood cut system developed by FPInnovations–Feric Division is increasingly being used as part of new ecosystem management approaches in eastern Canada. Feric evaluated the direct harvesting costs for the first entry phase in a shelterwood system implemented using the 1-2-3 method, which is also called shelterwood cutting with close selection. We compared the results of the partial cutting operation with those of harvesting with the protection of regeneration and soils (HPRS). The harvesting costs in the shelterwood approach can be up to $1.87/m³ more than in the HPRS treatment. However, the increased mean stem volume that is harvested as a result of the stem selection guidelines can mitigate this adverse impact in stands with large trees.

Abstract
Le système de coupe progressive 1-2-3 mis au point par FPInnovations, division Feric est de plus en plus utilisé dans le cadre des nouveaux développements de l’aménagement écosystémique dans l’est du Canada. Feric a évalué les coûts directs de récolte pour une première intervention d’un système de coupe progressive réalisée grâce à la méthode 1-2-3, aussi appelée coupe progressive avec sélection rapprochée. Les résultats des opérations de coupe partielle ont été comparés à ceux d’interventions effectuées au moyen de la coupe avec protection de la régénération et des sols (CPRS). Les coûts de récolte générés par cette méthode peuvent atteindre jusqu’à 1,87 $/m³ de plus qu’avec le traitement par CPRS. Par contre, l’augmentation du volume moyen par tige récoltée, induite par le choix de tige, atténue cet impact.

Abstract
L’éclaircie commerciale est un traitement sylvicole polyvalent qui peut être adapté à diverses structures forestières, dont celle des peuplements bi-étagés. Dans ce rapport, deux types d’éclaircie commerciale ont été comparés, soit une éclaircie par le bas et une éclaircie adaptée aux peuplements bi-étagés. Cette dernière a été réalisée à partir d’une prescription basée sur des critères de qualité des tiges sur pied. Les essais menés montrent que le traitement d’éclaircie adaptée a entraîné des coûts directs de 29 % inférieurs à ceux de l’éclaircie commerciale par le bas. Les résultats sur les peuplements étaient satisfaisants après traitement puisque la proportion d’arbres de bonne vigueur aux couronnes dégagées était importante.

Abstract
Feric evaluated the Bräcke M36a three-row mounder in cooperation with the Coopérative Forestière de Girardville and AbitibiBowater Inc. in the Lac Saint-Jean region of Quebec. The study’s main objectives were to identify a niche for the Bräcke M36a (the most appropriate site conditions) and to determine whether the mounder could increase scarification productivity by 50% thanks to the third mattock wheel. We performed a detailed study that measured plantability as a function of site conditions and a long-term study that determined overall productivity throughout the season

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
Five site preparation methods in a chunk-management harvest block were monitored from 1996 to 1998 and the resulting cost and productivity, site disturbance, and terrestrial lichen distribution are described in Phillips (2001). After nine years, there were few measurable differences in the impact of site preparation on lichen growth. Vegetative propagation, “seeding” with fragments of shrub lichen (Cladina spp.), increased the amount of lichen in all areas/treatments except on the wettest sites.

Abstract
Selection harvesting of tolerant hardwoods typically stops during the spring and early summer when there is heightened concern over damage to soils and residual stems from felling trees and machine activity. A feller-buncher and an 8-wheel forwarder modified into a clambunk skidder were evaluated as a lower impact alternative to conventional cable or grapple skidders to operate during the traditional shutdown period within acceptable guidelines for soil disturbance, residual stem damage and trail occupancy. This study showed that the feller-buncher and clambunk skidder used for single-tree and group selection harvesting could potentially extend the logging season into the spring shutdown period without exceeding local site impact guidelines.

Abstract
FPInnovations, division Feric a testé une méthode d’espacement adaptée aux travaux d’entretien dans des sites régénérés naturellement après coupe avec protection de la régénération et des sols (CPRS) au Québec. L’étude visait à vérifier si cette méthode était mieux adaptée à la structure distincte des peuplements issus de CPRS et de comparer la productivité des ouvriers dans un site de CPRS à celle qu’on obtient dans une coupe totale.Les résultats démontrent que la méthode adaptée a permis d’augmenter le nombre de tiges d’avenir de l’essence désirée, mais que le revenu des ouvriers était moins élevé dans les sites de CPRS.Une méthode de traitement ciblée aux sentiers de CPRS est aussi présentée dans ce rapport
