Abstract
Harvest operations on soft soils can be particularly challenging in order to respect site and soil disturbance guidelines as well as operational requirements. To address the challenges of operating on soft soils, FPInnovations has worked on solutions designed to reduce disturbance on weak soils while minimizing implementation and investment costs by using machines already being used in the operation.

Abstract
FERIC compared three harvesting systems (full-tree, tree-length, and cut-to length) on a clay site in northwestern Québec. None of the systems limited rutting to below the acceptable target level; however, cut-to-length harvesting (using a three-machine system) showed slightly better results than the other two systems.

Abstract
FERIC assessed a cable skidder with a dual-drum winch and radio remote control in hardwood partial-cutting operations. Productivity increased by up to 32% depending on the technology used, and ground disturbance decreased by up to 40%. Trail occupancy and damage to residual trees also decreased (by up to 53% and 79%, respectively). Operators entered the machine significantly fewer times, thereby improving safety. Remote controls are cost-effective for any machine, but dual-drum winches are probably too costly to install on older machines.

Abstract
Spruce Falls Inc. demanda a FERIC d' étudier deux debardeurs a grappin equipes de pneus larges et extra-larges afin de comparer leur productivite de meme que la perturbation du sol liee a leur utilisation. Le Timberjack 450C (figure 1) etait chausse de pneus extra­larges de 68 po (173 cm) de largeur fabriques par Rubber Applicators Inc. Le John Deere 648 etait equipe de pneus de 50 po (127 cm) de largeur provenant de United Tire and Rubber Co. Ltd., pneus d'usage courant dans les operations de Spruce Falls. Comme les deux debardeurs possedaient par ailleurs Jes memes capacites, nous croyons que les differences observees etaient principalement attribu­ables a la difference de largeur entre les pneus. Le terrain etait plat et le drainage variait de frais a tres mouille. Les peuplements etaient composes surtout d' epinette noire avec une faible proportion de sapin et de tremble.

Abstract
The objective of this study was to assess the potential for downsizing skidder requirements on soft ground through the use of high-flotation tires. The test was designed to compare the relative performance of a 90-kw skidder with conventional tires and chains to that of a 67-kw skidder equipped with high-flotation tires. The comparison criteria were short-and long-term productivity, fuel consumption, ground disturbance and operating costs. The trial was performed in the Abitibi region of Quebec under contract to the Ministère de l'Énergie et des ressources du Québec.

Abstract
In Canadian boreal forests, harvesting with protection of advance regeneration requires the creation of an intensively used network of skid trails. In this context, the effects of repeated skidder passes on soils were studied in terms of rut depth, the amount of displaced material in the trails, and soil bulks density. Two types of soil were studied: sands and clays. The factors that helped to explain the observed amount of soil disturbance were the number of skidder passes, the amount of wheel slippage, soil density, the soil's penetration resistance, and the soil's shear resistance. The results of the study indicated that the effects of skidder traffic on soil properties stabilized after a few skidder passes on sands, whereas the effects on clay soils continued to increase with an increasing number of skidder passes.
