Optimal distance among water diversion structures for mitigating runoff on the skid trails (case study: Kheyrud forest) [PDF]
مجله جنگل ایران, 2021 Using machinery wood extraction in steep slope in the Hyrcanian forests can increase the soil bulk density and soil compaction, decrease the infiltration water into soil of skid trail, which results in an increase runoff and soil loss and has detrimental

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 ...

Long-Term Effects of Timber Extraction by a Crawler Tractor on Soil Condition Recovery in a Mixed Forest [PDF]
مجله جنگل ایران, 2023 In this study, the physical, chemical and biological characteristics of compacted soil due to tracked skidding (LTT-100A) after 35 years (from 1986 to 2021) of clear cutting operation were investigated in an even aged mixed deciduous stand in Masal ...

The impacts of ground-based logging equipment on forest soil
Journal of Forest Science, 2014 Soil properties can be affected by heavy equipment used for skidding but these impacts vary greatly with site conditions and operational practices. We assessed the effects of ground-based skidding on site disturbance and soil physical properties. We also

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

The effect of sawdust mulch application on amount of runoff in the skid trails (Case study: Kheyrud Forest) [PDF]
مجله جنگل ایران, 2019 Forest machinery traffic on forests causes significant changes in increasing the bulk density, reducing porosity, ventilation and reducing water infiltration rate which resulted in an increasing surface runoff.

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.
