Investigating the performance of some improvement treatments in restoring soil physical properties of skid trails (Case Study: Darabkola Forest, Sari) [PDF]

مجله جنگل ایران, 2018
Logging operation by skidders can lead to soil compaction, rutting and erosion of skid trails. Therefore, in order to restore the soil physical properties of skid trails, it is necessary to perform improvement treatments.

Norway spruce production and static stability in IUFRO thinning experiments in the Czech Republic

Journal of Forest Science, 2021
Despite recent issues, Norway spruce remains the most important commercial tree species which might be demanded henceforth for its broadly utilizable wood. Even before foresters faced both the bark beetle outbreaks and spruce decline, spruce monospecific

Evaluating Post‐Fire Salvage Logging Erosion Mitigation Treatments in the California Sierra Nevada, USA

Hydrological Processes, Volume 40, Issue 7, July 2026.
Multiple pairs of mitigation treatments including logging slash, subsoiling, traffic passes and slope were evaluated over time using a rill simulation experiment to determine which treatments were effective at reducing runoff and sediment delivery from logged hillslopes.

Short-term recovery of fine root carbon stock is inhibited by skid trails in a humid tropical forest

iForest - Biogeosciences and Forestry
Impacts of logging on below-ground carbon stocks are less well understood than those on above-ground carbon stocks. Consequently, there is a sizeable knowledge gap regarding fine root recovery and their contribution to below-ground carbon stocks.

Calculating the correction factor of skidding distance based on forest road network

Journal of Forest Science, 2011
Average skidding distance for forest stands is an important parameter for the determination of the optimum road density and spacing. In this research the real mean skidding distance and theoretical mean skidding distance were measured to calculate the ...

Growth, mortality and regeneration responses to ecological forestry treatments are shaped by local factors, species, and initial treatment impact

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
In mixed stands, coniferous species showed growth benefits when coexisting with broadleaf species, possibly due to reduced intraspecific competition or improved access to resources mediated by broadleaf neighbours. This growth advantage was not observed for broadleaf species, indicating asymmetric benefits in mixed stands.

The effects of wood chips and slash usage on skid trail sheet erosion caused by log skidding using a farm tractor

Šumarski list, 2019
This study investigated the sheet erosion that occurs as a result of log skidding operations using a farm tractor on skid trails and the use of wood chips and slash in order to minimize the soil loss. A total of four blocks (sample fields) were formed in four designated skid trails in the study area and three runoff plots were established in each block.

Using LiDAR to quantify, map, and conserve late‐successional and old‐growth forest in Maine, USA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract The world continues to lose late‐successional and old‐growth (LSOG) forest as the human population and demand for wood fiber grow. However, older forest age classes provide structural and compositional characteristics important to biodiversity that are often not present in forests managed for timber.

Decision support system to find a skid trail network for extracting marked trees

Journal of Forest Science, 2017
Careful planning of skid trails as wood extraction routes in forests is an ongoing task and necessary for minimizing the environmental damage. The main objective of this study is to find skid trails to extract marked trees from stand sites to landing ...

A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

International Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 224-246, June 2026.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies
