“…Also, hydraulic properties of soils change after rainfall, which significantly influences infiltration, runoff and erosion (Erpul, Canga 1999;Horn et al 2007). The transport network plays an important role in the forest industry production of mountain regions where forest areas are scattered in vast territories (Byblyuk et al 2010). It seems mandatory that permanent skid trail systems should be developed for forest sites in order to concentrate all forest site operations to such irreversibly compacted area (Horn et al 2007).…”

“…It seems mandatory that permanent skid trail systems should be developed for forest sites in order to concentrate all forest site operations to such irreversibly compacted area (Horn et al 2007). The volume of soil erosion inflicted by forest machinery is a function of the gradient and length of slope, degree of soil erosion vulnerability, fraction of area covered by vegetation; intensity, duration, extension and frequency of precipitation (Ziegler, Giambelluca 1997;Grigal 2000;Byblyuk et al 2010;Fu et al 2010). Hence, measuring soil loss and sediment delivery are critical for quantifying and predicting the effects of timber harvesting activities in forested watersheds (Litschert, MacDonald 2009).…”

With increasing mechanization of forest harvesting operations the impacts on soil have increased quite dramatically. The objective of this paper was to examine the relationship of slope and soil loss. This research was carried out in parcels 14 and 26 of the third district of Nav-Asalem forest in the north of Iran. Erosion plots were 75, 150 and 225 m 2 with two slope classes. After each rainfall event the amount of runoff was measured; then, a sample was taken to determine the weight of soil loss. The results of correlation analysis by Pearson's test between soil loss and slope classes, soil loss and slope length showed that there was a significant (P < 0.05) and positive correlation between the mentioned factors. Also, linear regression between soil loss, slope length and slope gradient was significant. It could be concluded that studying and underlying factors that increase soil loss such as soil type, rainfall intensity, should also be taken into consideration in future. Skid trail construction and skidding should be limited to the slope of < 20%; machine traffic should be restricted. The above-mentioned conclusions can be applied to proper harvesting and management of forest ecosystems.

“…(Byblyuk et al 2010;Fu et al 2010). Other factors that can affect erosion are the quality of forest road surfacing material (asphalt road surfacing with the lowest effect and native road surfacing with ruts with the highest effect on erosion and with the 0.03 and 2 surfacing factors, respectively) and traffic (main highway and blocked road with the traffic factors of 120 and 0.1, respectively) especially during wet weather (Akay et al 2008;Khalipoor et al 2008).…”

“…Also, slope steepness is an important factor in soil erosion by water. Steep roads and skid trails lead to greater erosion rates (Luce, Black 2001;Sidle et al 2006;Byblyuk et al 2010;Fu et al 2010). Slope length also has a significant role in erosion.…”

A road network in forest lands provides easy access to forest resources for extraction, regeneration, protection and recreation activities. Erosion from forest roads and skid trails is a major concern in forest management due to the capability to cause adverse environmental effects. The objective of this paper is to introduce two methods for reducing erosion on forest roads and skid trails: water diversion and vegetation cover. Factors affecting erosion on forest roads and skid trails are climate, quality of forest road surfacing material, traffic, slope and vegetation cover. There are several management practices to mitigate the impact of logging and forest road and skid trail construction on stream water quality. Sediments delivered to streams from roads and skid trails lead to a number of dramatic effects on water quality and aquatic life. These management practices were found to be effective in controlling and reducing the runoff volume and soil erosion. Therefore, management and maintenance of forest roads and skid trails are essential elements to mitigate erosion.

Changes within the roadbed and the cutslope of an abandoned forest road—A case‐study from the Tatra Mts. (Poland)

The main aim of this paper was to determine the rate of erosion and aggradation within a forest road on different geological structures as well as a comparison of changes between roadbeds and road cutslopes. The research was conducted in the Lejowa Valley in the Tatra Mountains. The measurements of the forest road were performed using a Leica ScanStation C10 terrestrial laser scanner (TLS) with a set of six-inch Leica High Definition Survey (HDS) targets. Based on the multi-temporal digital elevation models (DEMs) two DEM of Differences (DoD) were created for the summer season of 2019 and the 2019-2020 period. The research has shown that there is a significant difference between the rate of relief change for roads constructed atop conglomerates and limestone. The net change for the road within conglomerates was an erosion of 432.37 m 3 ha -1 yr -1 , while for the road within limestone it was a sediment deposition which amounted to 3.87 m 3 ha -1 yr -1 . Research has shown that there exists a difference in the rate of erosion for road cutslopes and roadbeds constructed within conglomerates. It was shown that the erosion rate for the roadbeds was 1.7-times larger than that for the studied road cutslopes in the period 2019-2020. Improperly designed and constructed forest roads may be subject to intensive relief transformations, even after they are no longer in use.
