Changes in Soil Bulk Density Resulting from Construction and Conventional Cable Skidding Using Preplanned Skid Trails [PDF]
Northern Journal of Applied Forestry, 2007 Abstract A harvesting system consisting of chainsaw felling and cable skidder extraction was studied to determine soil bulk density changes in a central Appalachian hardwood forest site. Soil bulk density was measured using a nuclear gauge preharvest and postharvest systematically across the harvest site, on transects across skid trails,

Reducing erosion from forest roads and skid trails by management practices [PDF]
Journal of Forest Science, 2012 A road network in forest lands provides easy access to forest resources for extraction, regeneration, protection and recreation activities. Erosion from forest roads and skid trails is a major concern in forest management due to the capability to cause ...

Mathematical model of the interaction of wheeled skidder with skid trail in the rotate mode
Известия СПбЛТА, 2019 Вопросам взаимодействия колесного трелевочного трактора с пачкой древесины и волоком в режиме поворота уделяется недостаточно внимания. Разработанные математические модели не учитывают такие важные свойства объекта исследования, как упругодемпфирующие ...

Insufficient Logging Intervals Impede Upper Soil Recovery in Temperate Beech Forests: Insights From Two Case‐Studies in Poland [PDF]
Ecology and EvolutionLittle is known about how forest operations affect the biodiversity of soil microarthropods and the litter decomposition rate in temperate beech forests. This study aims to ascertain this information.

Effects of Skid Trail Slope and Ground Skidding on Soil Disturbance
Caspian Journal of Environmental Sciences, 2010 The effects of traffic frequency and skid trail slope on dry bulk density, litter mass and rutting are examined. Treatments included a combination of four different traffic frequencies (3, 7, 14, and 20 passes of a rubber skidder) and three levels of ...

Logging legacies in the Australian tropics: 56-years of skid trail recovery
Forest Ecology and ManagementGiven continued selective timber harvests from >500 million ha of tropical forest, forest managers need to know about its short and long-term avoidable and unavoidable consequences. Here we focus on long-term ecological impacts from an unavoidable disturbance, the soil and vegetation damage on skid trails used for log extraction. We studied recovery

Frontiers in Environmental Science, 2022 Forest roads, haul roads, and especially skid trails have been associated with sedimentation and soil erosion risk. Despite the widespread small shovel harvesting system on steep terrains in South Korea, the subsequent risks of deep (rut depth >5 cm ...

Fitocenološka združba kot kazalnik občutljivosti gozdnih tal za vožnjo gozdarske mehanizacije
Acta Silvae et Ligni, 2020 In the article we determine the suitability of the phytocenose as a basic unit for determining soil susceptibility to mechanized logging. A total of 90 measurements of skid trail profiles were taken on a 13.9 km long sample transect.

Available Nutrients Can Accumulate in Permanent Skid Trails [PDF]
Forests, 2017 Forest harvesting removes and redistributes nutrients through felling and forwarding. Substantial quantities of nutrients can accumulate in brash mats on permanent skid trails, but their availability and uptake after multiple thinnings on soils susceptible to leaching are unknown.
