“…Williamson & Neilsen (2000) found that a single pass by a rubber-tired skidder increased soil bulk density by 22% in the upper 10 cm in Tasmania. Rutting can have detrimental impacts on site productivity by creating preferential flow patterns for overland water flow, decreasing infiltration and gaseous exchange (Page-Dumroese et al, 2009).…”

Aim of study: The main aims of this study were to determine of damage level to residual stand and soil disturbance from mechanized selection logging.Area of study: Mixed beech stands in Caspian forests, northern Iran. Material and methods: Point-transect and systematic plot sampling were used for assessing damages to soil and trees, respectively.Main results: 89% of forest soil area was undisturbed or shallow disturbed, and 5.2% was deep disturbed. Soil bulk density of top 10 cm in the winching corridors, ruts and skid trails were increased 10.7%, 20.6% and 32.1% respectively than controlled area. Frequency of damages to regeneration and trees were 12% and 11.2%. The frequency of damages to regeneration was increased with increasing of their heights, but frequency of damages to trees was decreased with increasing of their diameter. The most type of damages was bole wounds in sizes of 100 to 200 cm 2 within 1 m from the ground level, and deep wounds. The frequency of damages was different in tree species (p = 0.001). The mean size of bole wounds was 174 cm 2 , and the mean height of bole wounds was 70 cm from ground level. The intensity of wounds on trees bole were decreased with increasing of their heights from ground level (p = 0.02), while their sizes were increased (p = 0.001).Research highlights: Winching of logs was the main cause of damages to soil and residual stand. The detailed planning strategy will reduce damage to level which is acceptable and predictable.

“…There are numerous classification systems for characterizing soil disturbance (e.g., Scott 2000;B.C. Ministry of Forests 2001;Heninger et al 2002;Page-Dumroese et al 2009). Regardless of the source of visual (qualitative) monitoring systems, they all include recognition that within a disturbance classification system, there are severity classes.…”

Soil properties and forest productivity can be affected during ground-based harvest operations and site preparation. The degree of impact varies widely depending on topographic features and soil properties. Forest managers who understand site-specific limits to ground-based harvesting can alter harvest method or season to limit soil disturbance. To determine the potential areal extent of detrimental (potentially plant growth limiting) soil disturbance based on site characteristics and season of harvest, we developed a predictive model based on soil monitoring data collected from 167 groundbased harvest units. Data collected included dominant site parameters (e.g., slope, aspect, soil texture, and landtype), harvest season, harvest type (intermediate or regeneration), and the machine(s) used during ground-based harvest operations. Aspect (p = 0.0217), slope (p = 0.0738), landtype (p = 0.0002), and the interaction of harvest season × landtype (p = 0.0002) were the key variables controlling the areal extent and magnitude of detrimental soil disturbance. For example, harvesting during non-winter months on gently rolling topography resulted in greater soil disturbance than similar harvest operations on landscapes that are highly dissected. This is likely due to the ease with which equipment can move off designated trails. A geospatially explicit predictive model was developed using general linear model variables found to significantly influence the areal extent of detrimental soil disturbance on nine defined landtypes. This tool provides a framework that, with local calibration, can be used on other forest lands as a decision support tool to geospatially depict landtypes susceptible to detrimental soil disturbance during ground-based harvest operations.Résumé : Les opérations de récolte et de préparation de terrain qui se déroulent sur le terrain peuvent avoir un impact sur les propriétés du sol et la productivité de la forêt. L'ampleur de l'impact varie énormément selon les caractéristiques topographiques et les propriétés du sol. Les aménagistes qui comprennent les limites inhérentes à chaque station pour la récolte sur le terrain peuvent modifier les méthodes de coupes ou la saison de récolte afin de minimiser la perturbation du sol. Pour déterminer l'étendue aréale potentielle des perturbations néfastes (qui peuvent limiter la croissance des plantes) du sol selon les caractéristiques de la station et la saison de récolte, nous avons élaboré un modèle de prédiction basé sur des données de suivi du sol collectées dans 167 unités de récolte sur le terrain. Les données qui ont été recueillies incluaient les principaux paramètres de la station (p. ex. pente, exposition, texture du sol et type de sol), la saison de récolte, le type de coupe (intermédiaire ou de régénération) et la machinerie utilisée lors des opérations de récolte sur le terrain. L'exposition (p = 0,0217), la pente (p = 0,0738), le type de sol (p = 0,0002) et l'interaction entre la saison de récolte et le type de sol (p = 0,0002) étaient les principales...

“…The modification of lower forest layers, as a result of thinning, has been studied widely (Burova and Feklistov 2007;Feklistov and Torbik 2011;Levkovskaya and Sarnatsky 2013;Solgi et al 2015;Cambi et al 2015;Naghdi et al 2016;Dymov 2017). However, such studies mainly investigated the strip thinning carried out with heavy equipment, and several studies have focused on soil compaction and tracks as a result of forest management (Murphy et al 2004;Page-Dumroese et al 2009).…”

Thinning of young forests attracts the attention of scientists despite the long-term commercial effect. However, these researches are scarce. Therefore, it is important to study experiments with a long history. The aim of our study is to investigate the impact of thinning carried out in young pine/birch boreal forests on stand formation, natural regeneration, ground cover and properties of the soil layers in stands. We investigated three types of thinning in young pine/birch forests. In one plot of the initial stand, thinning was performed in two stages with a time interval of 27 years; in the first stage, thinning intensity was 75% of stems, while in the second stage, thinning intensity was 30%. In two other plots, thinning was performed in one stage at a stand age of 13 years, with thinning intensities of 76 and 84%. At the stand age of 72 years (2017), integrated studies of the silvicultural and ecological states were carried out. All thinned plots had developed into pure pine stands with 28–53% thicker stems, 12–18% higher trees and a growing stock 55–92% higher compared to the un-thinned reference stand. The most pronounced differences were observed for Option 1. With thinning, forest type changed to red whortleberry type, while the un-thinned reference site developed into a blueberry type forest. Thinning in young pine/birch stands results in the formation of pure pine stands. The associated modification of environmental properties changed the composition and density of the ground cover and some properties of the upper soil layers. Two-stage thinning had the least impacts; this approach can be used to produce stands with high commercial value. It is especially recommended for young pine/birch forests in the northern taiga.
