Data gathered from tree-anchorage field experiments conducted in West Scotland, and from 3D digitising of large root systems, were used in developing the ECOSLOPES models of tree architecture, slope stability and tree stability. Search terms in quotes will enable a more specific search e.g. These come in two different forms: erosion control blankets and fiber rolls. Amplifying this in Technical Bulletin No. In addition to appropriate plant selection, nonplant features such as terracing, boulders and retaining walls may be options to consider. Finally, implications of vegetation cover for slope stabilization are illustrated by case studies. Coarse and fine roots form a dense network that binds soil together on slopes, and play a major role in minimising soil loss in both rural and urban areas. Clearing debris are piled and burned or join the stumps over the bluff edge. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Vegetation (trees, shrubs, grasses, flower and ground covers) helps stabilize slopes in numerous ways. Amplifying this in Technical Bulletin No. https://doi.org/10.1016/j.earscirev.2020.103328.

In addition to appropriate plant selection, nonplant features such as terracing, boulders and retaining walls may be options to consider. Both processes can affect the safety of people living or working on or near slopes, and on the quality of water for people living in the wider area. companion publication, Slope Stabilization and Erosion Control Using Vegetation, that will be published concurrently with this guide. How roots create a stable channel when growing in the soil. Slope instability can become a headache for many civil engineering projects and industrial facilities. Native plants provide wildlife habitat, are adapted to our native soils, can adapt better to climate disruptions, and interact with each other in ways hybrid/exotic plant communities do not. Stabilization is maximized when there is a multi-level canopy that has trees, shrubs and groundcover because the combination provides deep and shallow spreading roots. A couple of the hardiest trees for slopes are “Kilmarnock” willow (Salix caprea “Kilmarnock”) and the red maple (Acer rubrum). Hydrological effect of the plant on slope stability is to reduce soil water content through transpiration, interception, and evapotranspiration. how to grow trees for slope stabilization program. Plant through the matting. The project has produced techniques and tools to improve slope stability and reduce erosion. Burning Bush (Euonymus alatus) – Slope Control Bush with Stunning Fall Color (anmbph/123rf.com) The influence of herbaceous vegetation on slope stability – A review. The surficial 0.6 meters (2 feet) of embankment soil at the slope face generally have no internal cohesion due to poor compaction. Ecoengineering is defined as a long-term ecological strategy to manage a site with regard to natural or man-made hazards (Stokes et al. and Nicoll, B.C. Across Europe, the effects of forest vegetation on soil stabilisation, rockfall and erosion were examined on a variety of reference sites. Knowledge of the vegetative contribution that can be considered in bioengineering was the hydrological and mechanical aspects (hydromechanical). In addition to appropriate plant selection, nonplant features such as terracing, boulders and retaining walls may be options to consider. How To: Reslope, if necessary to smooth erosion gullies, and replant native species above the rock toe. 103. Trees – Structure and Function 20: 701–712. and Achim, A. Slope/Rock netting drapes are frequently used as fast but temporary solutions. Services include bio-engineering solutions for slope protection. Old, natural slopes in rural and forest areas have often developed a degree of stability over time. In most cases, planting native plants by hand does not require a permit. It is advisable to use stump sprout deciduous trees, because if they are cut down by hand or are damaged as a result of an avalanche, or by windthrows or snowfall, … You'll like its horizontal plant form if you're looking for a selection that doesn't get too tall (3 feet) but that spreads and puts out big, tough roots that will stabilize the ground on a slope. Norris, J., Stokes, A., Mickovski, S.B., Cammeraat, E., van Beek, L.P.H., Nicoll, B.C. 1.2 Active Slope Stabilization (Protection/Netting) By the calculated use of anchors, dowels, rock bolts and tensioned cable strapping, slope netting can be tightly contoured to the rock face such that potentially unstable rock units are restricted from failing and an even stabilising force can be placed into the slope. Different fruit tree rootstocks are adapted to different conditions. Soils that have instability problems are not usually soils at all, but only incipient soils. © 2020 Elsevier B.V. All rights reserved. Groundwater may also have a similar effect from underneath the surface when it is present in excessive amounts. The expansion of urban areas, and associated deforestation and construction activities, are increasing the area of unstable or vulnerable slopes. Since each project is unique, GSI can design your slope stabilization solution that will specifically meet your requirements. Embankment soil at depth greater than 0.6M (2 feet) generally has an internal cohesion of at least 2.39 kilopascals (50 psf). Slope Stabilization On slopes that are being eroded away, slowing down of surface water is needed. A mixed planting of native grasses, herbaceous and woody ground covers, shrubs and trees, if space allows, is the best strategy for slope stabilization. Trees offer the best long-term slope stabilisation because their roots dig deep into the earth to seek water, and smaller rootlets spread throughout shallower ground, preventing runoff. To learn more about our slope rehabilitation services click here. There is little to no top soil or ground cover at all, the soil is eroding rapidly and beginning to uncover the roots of these large trees. Accordingly, ecological slope engineering aims at improving the stabilizing effect of vegetation by combining knowledge of ecology and engineering. Vegetation management is a crucial element of an overall shoreline management strategy. Plus, trees and shrubs on steep hillsides can help keep slopes from sliding. But artificial slopes within urban areas that are part of developments, or that are adjacent to infrastructure such as roads and railways, can be less stable, and may require stabilisation using engineering, bioengineering or ecoengineering methods. There are several ways to achieve this; Sow direct onto bare soil with either a conventional lawn mix or a wildflower perennial meadow mix ; On very steep sites sowing may not be an option. Peltophorum pterocarpumand Acacia mangiumexhibited R- and H-types root systems respectively and were also recommended for planting in the middle of the slope. of trees which normally take 2-3 years to be effective. THE PLANTING OF EVERGREENS NOT ONLY ENSURES SLOPE STABILITY, BUT ALSO ENHANCES THE LANDSCAPE. Purpose: To reduce the erosion of sediment and phosphorus into a lake by stabilizing a lake bank. Ecological slope engineering measures should address multiple ecosystem services. Acid-loving or ericaceous shrubs grow best in a pH range of 4-6, and ideally pH 5-5.5. Slope plantings. Slope Stabilization, Emergency Work. Deep mass movements (deep landslides) are difficult to control and require engineering solutions. ... (2017) for example, found in a meta-analysis that when earthquakes are a potential trigger for slope failure, sometimes trees are better for stabilization and sometimes herbaceous vegetation or shrubs are better, mainly depending on the species-specific influence on the slope hydrological conditions. Does steep terrain influence tree stability? Whenever I’m driving down the road and see a gnarly, out-of-control slope or a barren, mulch-laden incline pitted with washouts, my heart goes out to the person tending that piece of land. Plant and Soil 217: 1–15. HOW TO GROW TREES FOR SLOPE STABILIZATION PROGRAM THE METHOD, DEVELOPED BY THE CINCINNATI PUBLIC WORKS DEPARTMENT, INVOLVES THE USE OF PRE-CANNED TREES TO LOWER THE MOISTURE CONTENT OF UNSTABLE SLOPES. Whenever I’m driving down the road and see a gnarly, out-of-control slope or a barren, mulch-laden incline pitted with washouts, my heart goes out to the person tending that piece of land. A field investigation. These methods should, where possible, be combined with use of plants and trees to enhance the urban greenspace. Summary: Heavy rains during winter storms between March 29, 2006, and April 19, 2006, caused the uphill embankment near 304 Olympian Way to slip out and deposit soil and rock on the roadway. Shallower mass movement (shallow landslides) and erosion processes are more suitable for control using bioengineering or ecoengineering methods that will have the added benefit of enhancing the urban greenspace. Geogrids can be used to … Spirea is a popular shrub for slope and erosion control and is hardy in 5 through 9. Without a doubt, gardening on an exposed slope can be an absolute nightmare. If branches on fallen trees are in your way, prune them instead of removing the trees. Turf grass is often a choice but consider the maintenance difficulties. P. indicuswere categorised as VH-type and the trees were recommended for planting in the middle of the slope. … By continuing you agree to the use of cookies. Springer, Dordrecht, the Netherlands. How to Easily Install a French Drain for Diverting Run-off . Towards developmental modelling of tree root systems. STABILIZATION - Techniques to Control Erosion and Protect Property - Coconut logs, live stakes, toe of slope protection and riparian restoration - Photograph courtesy of Register-Nelson Environmental Consultants. Decisions on suitable methods for slope stabilisation first require an evaluation of the hazard. I have a very steep backyard that has dozens of large, mature trees (tulip poplars and maples are two species). In most cases, planting native plants by hand does not require a permit. The degree to which trees may influence stability on a given slope is a complex function of various specific, interacting physical, biotic, and human-related factors. Planting on steep slopes may be regulated, so check with your local government. Geogrids can be used to increase surficial stability … Some nurseries feature blends for slope stabilization. Knowledge of the vegetative contribution that can be considered in bioengineering was the hydrological and mechanical aspects (hydromechanical). Trees offer the best long-term slope stabilisation because their roots dig deep into the earth to seek water, and smaller rootlets spread throughout shallower ground, preventing runoff. We use cookies to help provide and enhance our service and tailor content and ads. This bush grows 1 to 8 feet tall and up to 6 feet wide, is a low maintenance plant and needs little to no pruning. British Standards Institution, London. The high of construction above the surface of … Worldwide, shallow slope failure is a problem causing environmental and economic damage. Slopes are all around us in the urban environment, and the soil on some of these slopes may be inherently unstable. FEMA prepared permanent work (category C) Project Worksheet (PW) 440 for $626,313 to erect a soldier pile retaining wall. Best Fruit Trees for Slopes Black walnut (zones 4-9): A grand tree that produces fruity nuts in early to mid-fall Hickory (zones 4-8): A tree that can tolerate all soil types and produce tasty hickory nuts in fall 1.2 Active Slope Stabilization (Protection/Netting) By the calculated use of anchors, dowels, rock bolts and tensioned cable strapping, slope netting can be tightly contoured to the rock face such that potentially unstable rock units are restricted from failing and an even stabilising force can be placed into the slope. The review showed that slope stabilization concepts are developed insufficiently for herbaceous vegetation and thus future research should address the specific stabilization mechanisms, including vertical and horizontal root connections, as well as root distribution, geometry, and tensile strength. The plan below frames the existing view, and adds a beautiful landscape to help hold the slope and attract wildlife. The degree to which trees may influence stability on a given slope is a complex function of various specific, interacting physical, biotic, and human-related factors. Depending on the specific context, either herbaceous or woody vegetation can be more suitable for slope stabilization, or both can perform similarly. Melastoma malabathricum, Dillenia suffruticosa A mixed planting of native grasses, herbaceous and woody ground covers, shrubs and trees, if space allows, is the best strategy for slope stabilization. Movement of soil and rock down unstable slopes due to gravity is called mass wasting; surface movement resulting from the effects of wind and water is called erosion. The top of the bluff is graded to remove topographic irregularities and allow free access to the edge. They are built rectangular to the slope and in contour lines direction consistent of 15-20 or and 25- 30 living branches of Salix, Eleagnus, Platanus e.t.c. "Ash". Vegetative Contribution to Slope Stability at Magnolia Park (by Kathy Parker, 1996) recommends Oregon grape (Mahonia), which she suggests for gentle slopes. Therefore, after a first slope stabilization with seeding, some stump sprout deciduous trees are transplanted as naked rooted, container or root ball plants. (2008). Stabilization is maximized when there is a multi-level canopy that has trees, shrubs and groundcover because the combination provides deep and shallow spreading roots. To address water, you can install a surface or subsurface drain system. Mowing is challenging and water will simply run off this high moisture loving plant. of trees which normally take 2-3 years to be effective. Not only can this be more visually appealing, but the variety will attract more birds and wildlife and break the rainfall, which reduces erosion. The application of plant for slope stabilization is known as bioengineering. Methods include using brush mattressing to minimise erosion, and the planting of shrubs, plants and trees to stabilise the soil. Asked April 26, 2017, 10:15 AM EDT. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Photographs are from members of The Vetiver Network International, which promotes the use of vetiver systems for sustainable projects throughout the world. P. indicus were categorised as VH-type and the trees were recommended for planting in the middle of the slope. Fallen trees on the beach protect embankments from wave action. To accomplish this installation of devices meant to slow down the water is needed. A range of bioengineering and ecoengineering methods for slope stabilisation are described by Norris et al. Riverbank stabilization along the Green River has been a growing concern for years, and plans to use a log combo as a means for stabilization have been in the works for the past several years. (2007). Herbaceous vegetation responds faster to environmental changes than woody vegetation. To accomplish this installation of devices meant to slow down the water is needed. In an area where heavy precipitation is to be expected, it is possible that the soil may be loosened up enough for significant portions of the slope to slide down. The architecture of Picea sitchensis structural root systems on horizontal and sloping terrain. The removal of plantation trees, and the impact of repeated forest fires on slope degradation were evaluated, along with the recovery of the ecosystem and consequences for erosion. (2008). Movement of soil and rock down unstab… Canadian Journal of Forest Research 35: 2360–2367. the method, developed by the cincinnati public works department, involves the use of pre-canned trees to lower the moisture content of unstable slopes. 1998/2 (Hengchaovanich, 1998) and followed up by a number of presentations in several countires, that expounded the efficacy of vetiver for slope stabilization, the enginering sector has begun to take notice of vetiver (Grimshaw, 2003). Trees on the slope and crest are removed or topped to open up the view. Other smaller plants she lists are: Polystichum munitum (native sword fern) Vaccinium ovatum (evergreen huckleberry) Therefore, it is important to integrate ecological processes related to herbaceous plants into research and planning approaches. 1998/2 (Hengchaovanich, 1998) and followed up by a number of presentations in several countires, that expounded the efficacy of vetiver for slope stabilization, the enginering sector has begun to take notice of vetiver (Grimshaw, 2003). Turf grass is often a choice but consider the maintenance difficulties. Soil stabilization on steep slope with large, mature trees. This bush grows 1 to 8 feet tall and up to 6 feet wide, is a low maintenance plant and needs little to no pruning. and Cammeraat, L.H. It is neither usually realistic nor safe to maintain close-mown grass on a steep bank or slope. … On steeper slopes coarse coconut matting or similar material can be pegged down so that the soil on the slope, temporarily cleared of vegetation, is less likely to wash off. Plus, trees and shrubs on steep hillsides can help keep slopes from sliding. These come in two different forms: erosion control blankets and fiber rolls. Deep rooted plants help stabilize soil, trees add dimension and shade to prevent excess evaporation, and low growing ground covers cover up unsightly areas with ease of care. Willows (Salix spp.) ... (2017) for example, found in a meta-analysis that when earthquakes are a potential trigger for slope failure, sometimes trees are better for stabilization and sometimes herbaceous vegetation or shrubs are better, mainly depending on the species-specific influence on the slope hydrological conditions. The plan below frames the existing view, and adds a beautiful landscape to help hold the slope and attract wildlife. Trees on the bluff top are cut; their stumps and roots are pulled and pushed over the crest. ECOSLOPES (Eco-engineering and conservation of slopes) was a multidisciplinary EC-funded project that was completed in 2004. Cotoneaster horizontalis (zones 5 to 7) is another choice from the shrub world that is among the best plants for erosion control. Research conducted by Forest Research into soils and the development of tree roots has been used in developing models and decision-support systems for using vegetation to help stabilise soils. The application of plant for slope stabilization is known as bioengineering. Slope stabilization by vegetation depends on the location and species composition. (1999). such as Scouler, Sitka and Pacific have fibrous, widespread roots and tend to grow quickly. In this literature review, we critically discuss the slope stabilization potential of herbaceous vegetation as compared to woody vegetation and summarize the state-of-the-art knowledge on slope stabilization with herbaceous vegetation. Melastoma malabathricum, Dillenia suffruticosa Trees & shrubs for shoreline & streamside erosion control Read our operational statement about COVID-19. Fig. Willows (Salix spp.) Vegetation (trees, shrubs, grasses, flower and ground covers) helps stabilize slopes in numerous ways. These fallen trees may also serve as “sediment traps”, helping build beaches or provide more buffer at the water’s edge. Marine Shore Trees Marine Shore Shrubs Stream Trees Stream Shrubs; Douglas fir: Ocean spray: Douglas fir: Ocean sprey: Bigleaf maple: Salal: Bigleaf maple: Red-osier dogwood: Madrone: Snowberry: Western red cedar: Red elderberry: Western red cedar: Vine maple: Black cottonwood: Sitka alder: Willow: Serviceberry: Willow: Shore pine: Oregon grape: Paper birch: Vine maple: Evergreen huckleberry Spirea is a popular shrub for slope and erosion control and is hardy in 5 through 9. The use of use vegetation (fast growing grasses, shrubs and trees) in combination with coconet, geotextiles material and slope drainage system. SLOPE STABILITY ANO STABILIZATION METHODS Second Edition LEE W. ABRAMSON Hatch Mott MacDonald Millburn, New Jersey THOMAS S. LEE Parsons, Brinckerhoff, Quade & Douglas San Francisco, California SUNIL SHARMA University of Idaho Moscow, Idaho GLENN M. BOYCE Parsons, Brinckerhoff, Quade & Douglas San Francisco, California A Wiley-lnterscience Publication JOHN WILEY & SONS, INC. … A north-facing slope or north side of a building is a good site for frost-sensitive crops such as peaches, Japanese plums, sweet cherries, and apricots. As the uprooting of trees in damaging storms can contribute to a considerable increase in the loss of soil from steep sloping sites, Forest Research staff compared the stability and root architecture of trees growing on sloping and horizontal ground. This imbalance of knowledge leads to the broad perception that woody vegetation is generally better for slope stabilization than herbaceous vegetation. Slopes are all around us in the urban environment, and the soil on some of these slopes may be inherently unstable. Plant Biosystems 141: 481–501. /rrl/ supplemental notes: vol2, no5, pp26-29, 14phot They may be overly steep and they may be subjected to inundation or gullying. and more natural slope. It's always best to take cues from nature, so I think the best approach to a slope or hillside is a combination of trees, shrubs, and ground covers. It can be applied on flat slopes with rough surfaces. Issues regarding sealevel rise, beach nourishment, regulatory management of shorelands and other important topics are likewise not addressed here. Mix some Penstemons in for more color, some Manzanitas and Ceanothus for texture and long term slope stabilization and you have a winner. Slope stabilization by vegetation depends on the location and species composition. Digitising 3D root architecture data allows us to analyse the symmetry and density of tree roots that have grown on slopes. In general, peaches, sweet cherries, Japanese plums, and apricots do better in sandy soils; apples, pears, tart cherries, and European plums do better in heavier soils. Dry-seedingis an easy method where seed (10-25 g/m2) and organic fertilizer (100 g/m2) are scattered by hand or machine. Old, natural slopes in rural and forest areas have often developed a degree of stability over time. 4: Fascines for slope stabilization (construction pattern) (Schiechtl and stern 1992) 2.5 Wood fences Wood fences are dead parts of trees or bushes. Bush mattress construction with living brunches can be used (which will sprout) for protection and slope stabilization. Deep Slope Erosion Control and Embankment Stabilization. Mowing is challenging and water will simply run off this high moisture loving plant. Stabilize the upper soil layer on embankments with the 3D GEOWEB® Slope Protection System to resist sliding, prevent severe erosion caused by surface runoff, and allow steeper slopes to be built. It … (2005). Nicoll, B.C., Achim, A., Mochan, S. and Gardiner, B.A. Slope Stabilization, Emergency Work. Deeper, rooted woody vegetation helps to prevent shallow mass movements. The use of use vegetation (fast growing grasses, shrubs and trees) in combination with coconet, geotextiles material and slope drainage system. A mixed planting of native grasses, herbaceous and woody ground covers, shrubs and trees, if space allows, is the best strategy for slope stabilization. Slope Stabilization. Not only can this be more visually appealing, but the variety will attract more birds and wildlife and break the rainfall, which reduces erosion. Ecological interactions are very important when working with herbaceous vegetation. Since each project is unique, GSI can design your slope stabilization solution that will specifically meet your requirements. If used appropriately, each of these methods can have an added benefit of enhancing the urban greenspace. Such hazards include landslides, rockfall and erosion. the planting of evergreens not only ensures slope stability, but also enhances the landscape. Embankment soil at depth greater than 0.6M (2 feet) generally has an internal cohesion of at least 2.39 kilopascals (50 psf). Burning Bush (Euonymus alatus) – Slope Control Bush with Stunning Fall Color (anmbph/123rf.com) Thus, the study suggests that L. leucocephala is the best choice for slope stabilization work as it exhibits outstanding root mechanical properties. FEMA prepared permanent work (category C) Project Worksheet (PW) 440 for $626,313 to erect a soldier pile retaining wall. Wherever possible, the use of vegetation should be encouraged as part of the strategy to minimise soil loss. The most common method of hill and slope stabilization is the seeding of a grass and herb mixture. Sunset Manzanita and Harmony Manzanita with some Ceanothus make a great bank cover. Hydrological effect of the plant on slope stability is to reduce soil water content through transpiration, interception, and evapotranspiration. Bioengineering techniques combine engineering methods with natural or living materials to protect or restore slopes and reduce erosion. The development of symmetry, rigidity and anchorage in the structural root system of conifers. Use: Stabilization of top soil layers, slopes of fine material or bank toes, drainage of wet zones . Sunset Manzanita and Harmony Manzanita with some Ceanothus make a great bank cover. We found that performance of both woody and herbaceous vegetation is highly variable and depends on specific local growth conditions, location-specific requirements, species composition, and plant health. The Pacific willow (Salix lucida) is frequently used to stabilize slopes and control soil erosion, especially along streambanks. Nicoll, B.C., Berthier, S., Achim, A., Gouskou, K., Danjon, F. and van Beek, L.P.H. While groundcover and shallow rooted plants are good for prevention of surface erosion, large deep rooted trees are essential to the stability of slopes. Slope stabilization by vegetation depends on the location and species composition. Control of Major Accidents Hazards Regulations 1999, Methods of Testing Soils for Civil Engineering Purposes, Sustainable urban drainage systems (SUDS), European Council Directive 96/82/EEC on the control of major accident hazards. Forest Research conducts research on tree root development and anchorage, and provides advice on soils and the selection of suitable species for planting. Planting on steep slopes may be regulated, so check with your local government. Future research should address species combinations, spatial layouts and succession. Thes… Mix some Penstemons in for more color, some Manzanitas and Ceanothus for texture and long term slope stabilization and you have a winner. However, in a less formal setting long grass can be a good option. such as Scouler, Sitka and Pacific have fibrous, widespread roots and tend to grow quickly. Physical factors include slope geometry and gradient, geologic materials, stratigraphy, hydrology, and the local effects of shore processes.
