Decay evaluation of damaged beech trees (Fagus orientalis L.) adjacent to skid trails by nondestructive stress wave technique [PDF]
تحقیقات جنگل و صنوبر ایران, 2012 Ground skidding damages the marginal trees of the skid trails and may decrease their growth increment at long period. In this research the effects of ground skidding on decay development and extent of the beech trees (Fagus orientalis Lipsky) adjacent to

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.

Effects of Ground-Based Skidding on Soil Physical Properties in Skid Trail Switchbacks [PDF]
Croatian Journal of Forest Engineering : Journal for Theory and Application of Forestry Engineering, 2019 Effective skid-trail design requires a solid understanding of vehicle-soil interactions, yet virtually no data exist on the effects of harvest traffic on soils in the switchback curves common in mountainous terrain. We contrast for the first time the effect of skidding on dry bulk density, total porosity, macroporosity, and microporosity in the ...

Effects of wood extraction using farm tractor on soil physical properties (Case study: Gorazbon district in Khyrud forest) [PDF]
تحقیقات جنگل و صنوبر ایران, 2014 Tractor-based logging systems are the most common type of small-scale equipments. Farm tractors equipped with a 2-wheel trailer are mostly used to perform forwarding operations of pulpwoods and fuelwoods in the Hyrcanian forests of Iran.

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.

Assessing the relationship of slope and runoff volume on skid trails (Case study: Nav 3 district)
Journal of Forest Science, 2012 The effect of slope on runoff volume was evaluated on skid trails in the natural forest in the north of Iran. The objective of this study was to determine the relationship between runoff volume and slope in order to control runoff and skid trail ...

Optimization of Skid Trails and Log Yards on the Amazon Forest [PDF]
Forests, 2019 Research highlights: We used Dijkstra Algorithm (DA) to define optimal allocation of yards in order to minimize total skid-trail’s distance in the Amazon Forest. DA minimized trails’ distances and associated transportation costs, leading to an even smaller value when the current planning was disregarded and suggesting the reduction of deleterious ...

Runoff and Soil Erosion Assessment on Forest Roads Using a Small Scale Rainfall Simulator
Hydrology, 2016 Forestry operations can significantly alter hydrological and erosional processes in a catchment. In the course of developing timberland, a network of persistent roads and skid trails causing soil compaction is usually established.

Design of skidding trails at untapped cutting area
Forestry Bulletin, 2022 The method of designing variants of skidding trails nets is considered for cutting areas which has undeveloped areas (areas of young trees, swamps, territories of natural objects, etc.) when parameters are changed for slope angles of main and strip skid trails and the location of the loading point. An algorithm is developed and presented for allocation
