Abstract
A commercial thinning study in mule deer winter range was performed in the interior of British Columbia. The commercial thinning was followed by a pre-commercial thinning operation to create a clumpy, multi-storied stand with gaps for regeneration. The Forest Engineering Research Institute of Canada (FERIC) monitored the commercial thinning and pre-commercial thinning operations and determined the costs and productivities of these phases.

Abstract
This report documents the volumes of fiber harvested and left behind with two mechanized harvesting systems: a full-tree system and a cut-to-length system. Each system was observed in two 5-ha study blocks, one that had been harvested in the summer and the other harvested in winter. The full-tree system was also followed through the debarking-slashing center so as to evaluate the fiber loss incurred during mill yard handling operations, as well as during debarking and lashing. Breakage of and damage to harvested wood were also estimated for the two systems.

Abstract
During the winter of 1998-1999, FERIC and Quebec's Ministère des Ressources naturelles evaluated three methods of installing temporary stream crossings on winter roads. This report provides a detailed evaluation of the following three structures: a culvert stabilized with snow, a culvert stabilized with tree stems, and a crossing made solely from compacted snow. The study showed that these temporary structures could eliminate sedimentation of the streams and were generally less expensive than permanent structures.

Abstract
Trials of spot scarification with an excavator were conducted in the Abitibi-Témiscamingue region of Quebec to compliment the natural regeneration of harvested sites. The technique consisted of concentrating the scarification where advance regeneration was less abundant so as to improve the site’s stocking. Thanks to the flexibility of the excavator, spot scarification produced microsites suitable for in-fill planting or seeding, while preserving a large proportion of the softwood advance regeneration. A winter treatment with simultaneous seeding was also tested for sites that are inaccessible during the summer. The results demonstrated that the productivity of a treatment based on partial scarification with an excavator depended on the treatment intensity, and that the use of this treatment in winter did not significantly reduce the operation’s productivity.

Abstract
Winter resource roads are used only during frozen conditions. Constructing water management features at the end of winter when the ground is hard can be difficult and may lead to poor performance of the water management feature. Pre-planning water management techniques that are to take place during winter road decommissioning will provide a greater chance of successful performance and improved efficiencies. Construction of frozen road or ditchline is difficult but can be facilitated through the use of correctly sized equipment, and attachments designed for the task.

Abstract
Crushing, also commonly known as trampling, is a method of site preparation whereby heavy machinery is used to knock down an rum over dead and unmerchantable trees, and unwanted vegetation. This treatment is usually followed by a prescribed burn or a slash windrowing operation to eliminate as much of the downed material as possible prior to planting. This method of site preparation has been practiced in the past in Ontario for the treatment of difficult sites. Despite its limited use and the operational concerns involved, there is potential for this type of treatment on sites having heavy residuals and brush. This report gives details and results obtained during field studies undertaken by FERIC on two Winter crushing operations in Ontario.
