“…In this study, we showed that although no heavy machines were used for skidding and cleaning during or after the harvesting, high-intensity logging and clear-cutting significantly affected the soil bulk density, total porosity, temperature, and moisture regime (Figures 4 and 5). These findings are similar to those of previous studies by Hajabbasi et al [66], Hashimoto and Suzuki [68], Ares et al [11] and Gebauer et al [1], who reported that the absence of shade or the reduction of shade in intensively logged areas generally increases both the soil temperature and compaction. Zhou et al [8] reported similar findings for mixed forests in northeastern China, where an increase in harvesting intensity resulted in a decrease in soil organic matter, porosity, and water holding capacity, and an increase in soil bulk density.…”

“…Forests must be managed in ways that maintain their productive capacity, as well as the nutrient reserves in the soil, which facilitate the regeneration processes of the ecosystem [1]. In boreal forests, the compaction due to harvesting has significant consequences for tree regeneration [2], for the composition [3] and productivity of the forest [4,5].…”

“…In boreal forests, the compaction due to harvesting has significant consequences for tree regeneration [2], for the composition [3] and productivity of the forest [4,5]. Ground-based logging systems in particular can result in numerous negative consequences for the forest soil, such as decreasing water holding capacity, above ground nutrient content, availability of certain nutrients, and increasing soil compaction [1,[6][7][8][9]. The physical and chemical properties and the biological interactions of the soils are of great importance for tree growth and forest reproduction [6,10].…”

Scots pine (Pinus sylvestris L.) forests are one of the main vegetation types in the Asian forest-steppe zone. However, over-harvesting currently threatens the natural regeneration and sustainability of these forests. In this study, we examine the long-term effects of different logging intensities on soil properties and natural regeneration in a natural Scots pine forest in the West Khentii Mountains (Mongolia), 19 years after selective logging. Our experimental design included five treatments: clear cut (CC), treatments with high (HI), medium (MI), low (LI) intensities, and a reference parcel with no logging impact at all (RE). We described and quantified the harvest events and applied ANOVA and LMM modeling to analyze and explain the long-term impacts of the logging intensities on soil properties and natural regeneration. We found that logging has a significant negative influence on the physical and chemical properties of the soil because it increases soil compaction and reduces soil nutrients. The most critical impacts of logging were on soil bulk density, total porosity, organic matter, and total nitrogen and phosphorus. The LMM modeling showed that organic matter (OgM), total nitrogen (TN), available K (AK) and pH values are especially impacted by logging. Our study revealed that the values for all of these variables show a linear decrease with increasing selective logging intensity and have a level of significance of p < 0.05. Another finding of this study is that selective logging with low and medium intensities can promote natural regeneration of Scots pine to numbers above those of the reference site (RE). High intensity logging and clear-cuts, however, limit the regeneration of Scots pine, reduce overall seedling numbers (p < 0.05), and create conditions that are suitable only for the regeneration of deciduous tree species. This underlines the risk of Scots pine forest degradation, either by replacement by broad-leaf trees or by conversion into non-forest ecosystems.

Von ca. 50proz. Aktivierung an lieferte erneutes Umkristallisieren aus Benzol audi ein optisch aktives Erstkristallisat: es wurde in weitere Fraktionierungen eingesetzt.

“…In order to achieve this goal, the full productive capacity of forest stands needs to be maintained while preserving all the natural processes and constituents in the soil, including microbiological organisms, physical properties, nutrient reserves and regeneration processes of the ecosystem (Gebauer et al 2012). Timber harvesting is considered as a soil disturbing activity because it disturbs forest floor, exposes soils and may lead to sedimentation (Ballard 2000;Najafi et al 2009;Lotfalian, Bahmani 2011;Alexander 2012).…”

This paper deals with the issue of soil compaction during timber harvesting operations on cutting areas. Soil compaction was assessed following the logging operation in Darabkola forest area by measuring soil bulk density. In this research, a completely random sampling method was used to assess the resulting changes in soil bulk density. Soil bulk density was measured using bulk density sampler on felling, bucking, delimbing and control areas. The results showed that the bulk density value in the top soil layer increased with increasing tree volume and was not dependent on the terrain slope on the felling area. Also, there was a significant relationship between the bulk density value of felling area and tree volume. Further analysis showed that there was no significant relationship between bulk density values on felling, bucking, delimbing and control areas. It was shown that careful harvesting planning, restriction, skidding and directional felling limited the soil compaction and helped the soil conservation.
