    The system productivity of salvage logging by skidders and tractors was calculated as and m 3 h −1, respectively. In contrast to common logging, system productivity was about 6- to fold lower in salvage logging. The effective cost consumptions for the skidder and tractor were calculated as $ and $ USDm −3. The negative impacts of soil compaction on these methods for accomplishing this are the use of designated skid trail systems and soil tillage. \ ij h V il n St r4 n si Ci C(Ot P’ U! ef SC al an of so ail im, thi ag by Soil bulk densities in adjacent logging trail and undisturbed area on the Mount Hood National Forest.

Timber logging as carried out in the planned logging system, not only decreased cost of logging but also reduced impact in felling gaps, winching lines and skid trails 23%, 26 % and 21% respectively. For the planned logging system an average of about 1% of the area harvested was affected by skid trails, whereas in conventional logging the.

    LOGGING SOILS General All subsurface investigations of soils for construction materials and for most engineering purposes using test pits, trenches, auger holes, drill holes, or other exploratory methods should be logged and described using the standards in USBR [1] and [1] (Unified Soil Classification System [USCS]) in accordanceFile Size: KB. Soil, water, and gravity are what trail work is all about. Soil is your trail's support. The whole point of trail construction is to manage soil by keeping it where you want it. Water is the most powerful influence in the trail world and its mission is to remove your soil. The goal of good trail File Size: KB.

Designing skid trail systems to reduce soil impacts from tractive logging machines by Henry A. Froehlich Download PDF EPUB FB2

Logging on skid trails restricted to 10 percent or less of the harvested stand can reduce the area of compacted soil by at least two-thirds, In a comparative study, productivity of Douglas-fir logs per hour was just as great In an area with designated trails as In an adjacent area logged by: the impacts of soil compaction might be an efficiently planned system of skid trails covering only a small portion of the total harvested area.

This paper describes a study designed to test the feasibility of such a system. METHODS We studied the efficiency of log skidding with a trail system restricted to 10 percent or less of the har-vested area.

The study unit consisted of a stand of to year-old. Therefore, the impact of skid trails on tree growth in a given tract will depend on the amount of area in skid trails or the number of trees affected and on the relative increase in soil density in the skid trails.

Some forest managers have turned to skyline or even helicopter logging as a means of reducing site impacts from timber harvesting.

Exceeding trail standards in selected locations may be appropriate, such as the trail segment in the Little Miami Scenic Trail (OH)—a converted rail-trail that accommodates multiple use and is designed as fully-accessible.

A bare-soil skid trail leads downhill to a stream crossing.

Based on management objectives and environmental considerations, the model can design skid-trail networks that minimize skidding cost only by selecting skid-trails that reduce skidding cycle time from individual tree bunches to the landings, minimize soil recovery cost only by reducing the total length of skid-trails, or minimize both skidding and soil recovery costs Cited by: Chapter 3-Trail Layout.
