Production, Cost, and Soil Compaction Estimates for Two Western Juniper Extraction Systems
Harvesting trials were performed during the winter and spring of 2003–2004 in central Oregon to compare the costs, production rates, and soil compaction impacts of two systems for harvesting western juniper (Juniperus occidentalis). The two systems compared were a conventional system consisting of manual felling, delimbing, and bucking using a chainsaw and skidding logs with a rubber-tired grap...
متن کاملEffects of Stump Harvesting and Site Preparation on Mercury Mobilization and Methylation
Mercury (Hg) is an element of major concern in boreal freshwater ecosystems, due to high concentrations of Hg in fish. Forestry operations have been reported to increase the concentrations and loads of Hg to surface waters. In this thesis a series of catchment-scale experiments were used to determine forestry effects on total mercury (THg) and methyl mercury (MeHg) runoff concentrations caused ...
متن کاملSoil Disturbance Effects of Hoe-Forwarding on Tree Growth and Site Productivity: 15-Year Results at the Woss Study Site
These effects on tree growth, which may persist for several decades (Hatchell et al. 1970, Butt 1987, Miller et al. 1996), may lead to shortand long-term reductions in tree growth and forest productivity. The level of soil disturbance will vary with soil texture, forest floor thickness, and soil water content at time of harvest (Miller and Sirois 1986, Corns 1988). In addition, machine type, si...

متن کاملImpact of Site Disturbances from Harvesting and Logging on Soil Physical Properties and Pinus kesiya Tree Growth
A study was conducted to determine the impacts of soil disturbance and compaction on soil physical properties and tree growth and the effectiveness of tillage in maintaining or enhancing site productivity for intensively managed Pinus kesiya Royle ex Gordon sites in Dedza, Malawi. The results indicate that about fifty-two percent of the area of compacted plots was affected by the vehicular traf...
