“…The much longer lengths of these drainage features are due to the increased amounts of runoff and sediment flows from upslope, the accumulation and discharge of this runoff at a single location due to the road segment, and the reduced infiltration and roughness of the burned hillslopes below the road. Unpaved roads are recognized to have a heavy effect on several hydro-geomorphic processes, acting as a primary sediment source [7,12]. This is due to the lack of surface cover (differently from rock-paved roads), which exposes the road surface to both rainsplash, and overland and concentrated erosion [21].…”

“…The alteration of natural profiles of forests hillslopes and surface and subsurface water flows, the low plant cover, and the compaction of soil on the roadbed [10] are the factors that explain these processes [11]. The erosion features of forest roads are sources of increased erosion with enhanced land degradation [5], since soil is compacted by traffic and vegetal cover is low or absent [12,13]. Soil compaction and scarce vegetation reduce water infiltration, which on its turn enhances infiltration-excess overland flow, even for low-intensity rain events [14,15].…”

“…As reported by [16], wildfires and road construction may drastically reduce infiltration rates, thus increasing surface erosion rates by several orders of magnitude. Therefore, evaluating the erodibility of forest roads has an increasing importance [12], especially in forests burned by wildfires. The existing literature has mainly estimated sediment delivery rates as a function of upslope erosion rates but failed to isolate forest roads as site of erosion [5].…”

Forest roads are often subject to intense runoff and erosion, and the rates can be increased by other disturbance factors, such as wildfires. Since scarce literature exists on the effects of wildfires on rill erosion of forest roads, this study presents the first results of a wider research, evaluating rill erosion in four different types of roads on a forest in Hellìn (Castilla-La Mancha, Central-Eastern Spain): unpaved roads made of native materials (soil found at the study site) and rock-paved roads, both built in unburned areas as well as unpaved and rock-paved roads, in fire-affected areas. In general, the unpaved roads are more subject to rill erosion compared to the rock-paved roads. In particular, the road of burned areas shows an erodibility that is higher by more than 200% compared to the unpaved and unburned roads, and even by about 400% compared to rock-paved roads (in both burned and unburned areas). A modeling approach based on distance linear models and distance-based redundancy analysis has identified the slope of road surface and upstream hillslope as well as the percent bare soil over the road surface as important input variables to predict rill erosion in future modeling experiences. All these variables may be easily measured by quick field surveys. Although the analytical approach of this study is limited to the geometric characteristics of erosion features, the results and the methods developed are useful to support the activity of land managers to better understand the magnitude of road erosion and to develop efficient measures for its control and mitigation.

“…Thus, there are many environmental factors interacting with each other and influencing the soil structure and, consequently, the plant development (Ozkazanc et al, 2019;Aricak et al, 2020;Ozel et al, 2021;Koc, 2021). The climatic factors such as precipitation, temperature, and light (Kilicoglu et al, 2020;, the edaphic factors such as soil pH, amount of organic matters, and depth (Kravkaz Kuscu et al, 2019;Varol et al, 2019), the factors causing stress such as drought (Topacoglu et al, 2016;Mahmood et al, 2020), frost (Sevik and Karaca, 2016;Joshi et al, 2020), pollution (Mutlu et al, 2016;Mutlu and Aydın Uncumusaoglu, 2016;Mutlu and Kurnaz, 2017;Mutlu and Aydın Uncumusaoglu, 2017;Aydın Uncumusaoglu and Mutlu, 2017;Mutlu and Kurnaz, 2018;Turkyilmaz et al, 2018;Kükrer and Mutlu, 2019;Mutlu, 2019;Ucun Ozel et al, 2020;Emin et al, 2020;Kutlu and Mutlu, 2021;Tokatli et al, 2021), and human-origin factors such as fertilization (Moncada et al, 2021;Soumare et al, 2021), irrigation (Shu et al, 2020;Parkash et al, 2021), and hormone implementations (Guney et al, 2016a,b;Yucedag et al, 2019;Ashokhan et al, 2020) significantly affect each other, plant development, and soil structure. In conclusion, in order to determine the effects of enzyme activities on soil fertility and plant development and to use them purposefully, it is necessary to increase and diversify the future studies to be carried out on this subject.…”

Analysing the factors driving the population size and activities of soil microorganisms is important for understanding the soil ecosystem’s structure and functioning. For this purpose, the soil enzymes are used as an indicator of soil microbial activity and soil fertility. Although there are many studies on the distribution and activities of various soil enzymes in soils under monoculture or crop alternation conditions, there are only few studies examining the ecological relationship in natural ecosystems, especially by using enzymes. In this study, it was aimed to determine the effect of different land uses on the catalase enzyme activity in soil. For this purpose, the catalase enzyme activities in soil samples taken from 0-5cm and 5-10cm depths in agricultural, forest, and pasture lands in north and south exposures were determined and the effects of different land use, exposure, and soil depth conditions on the enzyme activities were investigated. At the end of the study, it was determined that the catalase enzyme activity significantly differed by the land use and the highest level of catalase enzyme activity in both south and north exposures and at both depth levels was found in forest soils, whereas the lowest level of activity was found in agricultural lands in north exposure and pasture soils in south exposure.

“…In fact, all living life in the world is largely depend on plants, either directly or indirectly [1]. As well as producing the necessary nutrients for other living things through photosynthesis, plants also function in many other ways such as reducing all kinds of air pollution in their environment [2][3][4], reducing noise [5,6], preventing erosion, balancing the climate and promoting positive effects on people psychologically [7][8][9][10]. In addition to these, they are an important economic resource [11,12].…”

Plants are living things that form the basis of food pyramid, provide numerous products and are considered as the source of life. Many professions such as agriculture, forestry and landscaping work on plant growing. The fast growth of plants is of prime importance since it provides advantage in light and root competition in the areas where plants are grown. For this reason, it is highly important to identify the factors affecting plant development and to change these factors in favour of the target species. In order to achieve this, first of all, the factors affecting the development of the target species in the study area should be known.In this study, which was carried out in the natural regeneration areas of Taurus Cedar (Cedrus libani A. Rich) found in the Kasaba Forest Sub-District Directorate in Kas region of Antalya, and was prepared as a term project, 3-year-old young cedars naturally grown in different stands were compared in terms of their root collar diameters, seedling length and number of seedlings, and the factors affecting the natural regeneration success were tried to be identified by factor analysis. As a result of the study, it was found that the average root collar diameter was between 2.5 and 4.7 mm, the average seedling length was between 4.5 and 11.3 cm, and the average number of young cedars per square meter was between 6 and 47. When the factors affecting the natural regeneration success were examined, it was found that the factors such as soil moisture, precipitation, amount of organic matter, light intensity and number of healthy seeds were the most important factors that played a role in this success, and that those factors explained 78.32% of the total variance.
