“…Meanwhile, the turf‐grass lost its efficiency over time due to vegetation cover reduction. These results are also consistent with many other researchers that previously tested buffer strips (Borin, Passoni, Thiene, & Tempesta, ; Duchemin & Hogue, ; Hay et al, ; Lee et al, ; Mankin et al, ; Patty, Real, & Gril, ; Wang, Duggin, & Nie, ). We observed that the maximum efficiency of the vetiver buffer strips occurred after about 4 months, coinciding with when the vetiver‐grass had reached its maximum growth and vegetation cover.…”

Effectiveness of vegetative buffer strips at reducing runoff, soil erosion, and nitrate transport during degraded hillslope restoration in northern Iran

Soil and water conservation in natural and cultivated areas is a major concern for humankind. However, there are severe problems with degraded hillslopes due to bare soils in northern Iran, which are one of the most important factors driving land degradation processes. Subsequently, soil erosion, pollutant transport, and/or nutrient impoverishment are affecting large territories; therefore, rapid and inexpensive soil conservation measures need to be implemented. The use of vegetative buffer strips could be an effective strategy to reduce pollutant transport as well as soil erosion.Thus, this research aimed to investigate the possible efficiency of two different vegetative buffer strips composed of vetiver-grass (Chrysopogon zizanioides) and native turf-grass (Festuca arundinacea) at reducing runoff and soil losses as well as nitrate transport on a representative degraded hillslope with bare soils in Mazandaran, Iran.Twelve 10 m 2 experimental plots were tested over 1 year using a runoff simulator that produced overland flow that corresponded to the 25-and 100-year return period rainfall events. The plots with bare soils had the highest runoff volumes (30.5 and 55.4 L m −2 ), sediment concentrations (101.2 and 430.6 g L −1 ), and nitrate concentrations (10.4 and 37.6 mg L −1 ). Vetiver was the most useful tool to reduce runoff, soil loss, and nitrate concentration, with values of 13.4 and 28.6 L m −2 , 13.4 and 90.9 g L −1 , and 2.9 and 16.4 mg L −1 , respectively. Of the treatments investigated, vetiver provided the most rapid cover and was the most efficient at preventing soil erosion and nitrate transport directly after plantation.

Voor een strook met een breedte van 5 meter, zijnde de minimale breedte om een beheerovereenkomst perceelsrand aan te vragen, bedraagt de vermindering gemiddeld 57%.…”

“…The greater complexity induced by wood in turn supports greater habitat diversity (Collins et al , ; Johnson et al , ), and thus can potentially support greater ecological abundance and diversity. Riparian forests can also reduce delivery of diffuse pollution through trapping of fine sediment runoff from agricultural land (Cooper et al , ; Daniels and Gilliam, ; Lowrance et al , ), storing sediment behind logjams (Davidson and Eaton, ; Wohl and Scott, ), remove nitrogen and phosphorous from runoff and subsurface flow (Peterjohn and Correll, ; Lowrance et al , ; Wang et al , ; Sutton‐Grier et al , ), and enhance stream metabolism (Blaen et al , ). Forested floodplains are a source of particulate organic matter to the channel (Gurnell et al , ), provide shade (Montgomery et al , ), help regulate water temperature (Garner et al , ; Garner et al , ; Ouellet et al , ; Dugdale et al , ) increase bank stability through root reinforcement (Shields and Gray, ; Beechie et al , ) and decrease the erosive power of the channel (Gregory et al , ; Manga and Kirchner, ; Fisher et al , ).…”

There is an increasing emphasis on using natural processes, including riparian forest restoration, to enhance the ecological, hydrological and geomorphological functioning of watercourses. However, we have insufficient knowledge on how the supply and retention of in-channel wood from riparian forest stands changes with age, with inferences typically based on data from terrestrial forests. This presents a challenge in estimating the efficacy and functional lifespan of restoration projects. In this paper, we use a riparian forest growth model to show there is a lag of up to 40-50 years between the start of forest growth and trees delivering wood to the channel that is large enough to resist fluvial transport, anchor logjams and so increase channel complexity and hydraulic resistance. Resource managers need to account for realistic timescales over which changes promoted by riparian woodland restoration will occur and may need to consider using interim engineered logjams as the forest develops.
