“…Although not always (Jordán-López et al, 2009), higher runoff rates in unpaved surfaces of forest roads have been generally reported by authors (Arnáez et al, 2004;Cao et al, 2013;Lotfalian et al, 2013) than in cut slopes, sidecast fill slopes or forest soils.…”

“…Consequently, the design of forest road systems is optimized for easy transport, traffic flow and accessibility, but other impacts are often ignored (Dabek et al, 2014). The assessment of risks associated to forest roads is necessary for adequate management of forest resources (Lotfalian et al, 2013). Great differences between soil physical characteristics in WT/CA plots and the undisturbed forest soil have led to different hydrological and erosional responses.…”

“…In previous investigations, deep rills on the surface of skid trails in the Darab Kola forest area have been reported, causing canalization of runoff flow and enhancing water erosion on steep slopes (Lotfalian et al, 2013). Reduced traffic safety, slope failure and risk for economic activities are some of the impacts of soil erosion risk associated to forest roads cited by Lotfalian et al (2013).…”

“…Extraction of timber from these forests has required extensive road networks to be constructed, nearly always without consideration for soil conservation and erosion mitigation (Parsakhoo, Lotfalian, Kavian, & Hosseini, ). Mechanical logging and skid trail construction have led to high rates of erosion on disturbed logging surfaces (Jourgholami & Etehadi Abari, ; Lotfalian, Parsakhoo, Kavian, & Hosseini, ; Safari et al, ). In addition, unsustainable cultivation practices (Kavian et al, ) and various other land use activities have accelerated erosion rates in the last several decades (Kelarestaghi & Jafarian, ).…”

Wood‐based mulches are a preferred erosion control material for rehabilitation of degraded lands because they can be made from native wood materials; however, research is needed to verify the effectiveness of new products prior to application. The present study aims to assess the effectiveness of two types of native wood strand mulches from Iran (waste byproducts of Alnus glutinosa and Fagus orientalis working) in reducing runoff, soil loss, and sediment concentration under laboratory conditions. Toward this goal, rainfall simulations were conducted 27 times using a 50 mm hr−1 rainfall during 20‐min experiments on erosion plots with treatments of different cover percentages (bare, 30 and 70%) and strand dimensions (16 and 4 cm in length; 1.5 cm wide). The results showed that all strand applications reduced runoff (>12%), soil loss (>47%), and sediment concentration (>44%) compared to the bare plots. The most effective application treatment was a 70% coverage of the 4‐cm strands of either material (p value < .002). The shorter strands were most effective for all hydrological and erosion variables reductions because they maintained more contact with the soil surface during simulated rainfall and then increased the soil retention potential, whereas the longer strands realigned in the direction of flow, thereby limiting their ability to retard flowing water. The small strands also facilitated the creation of microdams that blocked flow and promoted infiltration. Both materials were deemed effective native erosion control products in degraded sites in the Hyrcanian forests of Iran, particularly when small strands were applied at high cover rates.

“…Basic measures to reduce environmental damage to roads begin with the design and networking step (Lotfalian et al 2013). Therefore, in designing forest roads, not only the costs should be considered but also the proper management of water and soil.…”

This study aimed to investigate the effects of two types of natural geotextiles, including wood shred (WS), rice straw (RS) and the biomechanics method of brush wood dam (BWD) with planting seedlings of Alnus glutinosa and Salix alba on runoff, soil loss and fill slope. The effects were compared with those obtained from control treatment. A total of 36 plots (2×4m) with three replicates in the direction of gradient to fill slope of a forest road in northern Iran was considered. Soil moisture, canopy cover of seedlings, vegetation coverage, runoff, sedimentation and erosion were measured in plots during 12 months. BWD and WS played an effective role in reducing runoff by 57% and 73%, respectively. By using RS and WS, the sediment concentration was decreased by 23% and 11%, respectively, while by using BWD it increased by 58%. RS (24.16%) and BWD (7%) had the greatest and smallest impact on reducing vegetation coverage, respectively. BWD (33%) and RS (27%) had the highest and lowest canopy cover of seedlings, respectively. Results showed that both RS (22.23%) and A. glutinosa (4.96%) had the greatest effects on increasing soil moisture. Comparison between the planted species and the control treatment (with no seedlings) showed that S. alba was effective in reducing runoff (46.22%), while A. glutinosa was effective in reducing erosion (66.89%) and sediment concentration (53.52%). Finally, interactions between conservation treatment and planting of seedlings played a more effective role in controlling runoff and erosion. Therefore, the application of conservation treatments together with planting of seedlings is recommended in order to provide better soil conservation and restoration of fill slope.
