“…investigated the effect of soil moisture and light intensity on herbaceous and woody vegetation growth and found that there was a positive correlation between understory herb richness and soil moisture. The results of different studies were consistent with the results of our study that the removal of overstory vegetation cover increased the species richness in the area compared to the undisturbed control area(Bergstedt et al, 2008;Yılmaz et al, 2018;Çoban et al, 2019). Similarly,Battles et al (2001) also reported that species diversity was higher in more open and bare lands, and species richness increased linearly with the intensity of silvicultural activities.…”

Harvesting or degradation of forest ecosystems directly affects the microclimate, causing changes in air and soil temperatures and soil moisture in the forestlands. The objectives of this study were to investigate the effect of infrequent heavy defoliation of forest cover on some selected soil properties, ambient and soil temperatures, soil moisture, and herbaceous vegetation cover and determine their recovery in a short period in the area subject to infrequent clearcutting under the powerline corridors (PLCs). The study was conducted in the research forest of Istanbul University-Cerrahpaşa, Faculty of Forestry. The treatment plots were selected from the clearcut area and control plots were selected from an untouched oak-hornbeam forestland. Soil temperature and moisture, maximum and minimum ambient temperatures were measured in the treatment and control plots between 2020 and 2021 and topsoil was sampled between 2019 and 2021 years. Data were analyzed using analysis of variance (ANOVA) to test the effects of clearcutting on some selected soil properties in the short term after cutting. The clearcutting caused a significant increase in soil bulk density (BD), a decrease in the soil total porosity (TP) and soil hydraulic conductivity (HC), and saturation capacity (SC). Forest cover removal significantly decreased the soil organic matter (SOM) content by 3%, increased average soil temperature by 2.1 °C, and the difference between maximum and minimum temperatures by 8.8 °C. Additionally, clearcutting reduced the average soil moisture from 36% to 35%. The findings revealed that clearcutting negatively affected some hydro-physical soil properties and soil microclimate conditions that may not recover to their previous states within the next few years.

“…They have higher extinction rates compared to other shrub and woody species (Gilliam, 2007). Several studies highlighted the role clearcutting plays in the spread of invasive species (North et al, 2005;Çoban et al, 2019;Chen et al, 2020).…”

“…Results of this study showed higher alien species richness in areas closest to human settlements, where clear cutting was the most likely management strategy used. A combination of clear‐cutting and slash‐piling reportedly promotes vertical development of tree sprouts, which improved management actions in a study conducted elsewhere (Çoban et al, 2019). Their findings suggest similar methods were used in the study sites that had an abundance of common guava and gum tree Eucalyptus camaldulensis that were near human settlements.…”

Highways to invasion: Powerline servitudes as corridors for alien plant invasions

et al. 2023

Human use of powerline servitude corridors for the secure transmission and distribution of electricity disturbs natural landscapes and changes vegetation patterns. We examined vegetation communities under two powerlines in the Limpopo province, South Africa (Khakhu line 22KV and Fundudzi 132KV powerlines). Twelve invasive alien species were identified in Khakhu and Fundudzi, dominated by Khaki bush Tagetes minuta, common guava Psidium guajava, black-jack Bidens pilosa, fierce thorn apple Datura ferox and common lantana Lantana camara. Sites closest to human settlements showed high alien species richness, whilst sites located further away were dominated by alien L. camara, but had a low overall species richness. Conversely, areas away from human settlements showed lower levels of alien invasion. Weak overlaps in the principal coordinates analysis polygons for the two powerline servitudes suggest that alien plant compositions are dissimilar, with five identified species groups being identifiable among sites, and thus a high potential for invasion success from multiple taxa. The research findings showed that powerline corridors could potentially trigger invasion success via disturbance as they act as pathways for arrival and should be a focus for management efforts to prevent further spread.

“…While it has already been shown that 6% improvement in reliability and 9% reduction in total costs is possible by only optimising tree trimming tasks [10], utilities still spend millions of dollars on vegetation management every year, making it one of the costliest activities in distribution asset management [7]. In addition, new challenges are now emerging related to mitigation of long-term negative impacts on biodiversity and ecosystems' sustainability [11,12]. Accordingly, digitalization in vegetation management has been explored increasingly in the last decade, within which the use of Light Detection and Ranging (LiDAR) has gained considerable attention [13].…”

A Complete Environmental Intelligence System for LiDAR-Based Vegetation Management in Power-Line Corridors

et al. 2021

This paper presents the first complete approach to achieving environmental intelligence support in the management of vegetation within electrical power transmission corridors. Contrary to the related studies that focused on the mapping of power lines, together with encroaching vegetation risk assessment, we realised predictive analytics with vegetation growth simulation. This was achieved by following the JDL/DFIG data fusion model for complementary feature extraction from Light Detection and Ranging (LiDAR) derived data products and auxiliary thematic maps that feed an ensemble regression model. The results indicate that improved vegetation growth prediction accuracy is obtained by segmenting training samples according to their contextual similarities that relate to their ecological niches. Furthermore, efficient situation assessment was then performed using a rasterised parametrically defined funnel-shaped volumetric filter. In this way, RMSE≈ 1 m was measured when considering tree growth simulation, while a 0.37 m error was estimated in encroaching vegetation detection, demonstrating significant improvements over the field observations.
