Species Selection for Soil Reinforcement and Protection
International audienceSpecies selection is vitally important for ensuring the success of any ecotechnological solution that may be employed on a particular site. The purpose of this chapter is to provide the engineer with a database of plant species that are suitable for both soil and slope stability by either mechanical or hydrological means, i.e., anchoring and buttressing of deep tap roots; bank and channel reinforcement; deep reinforcement and soil strength enhancement; removing soil moisture, surface protection, shallow reinforcement and erosion control. Protection forests rely on the stability of trees to maintain their integrity especially during storms and with regard to rockfall or avalanches. We therefore provide guidelines as to which species best resist these abiotic forces on slope

How vegetation reinforces soil on slopes
International audienceOnce the instability process e.g. erosion or landslides has been identified on a slope, the type of vegetation to best reinforce the soil can then be determined. Plants improve slope stability through changes in mechanical and hydrological properties of the root-soil matrix. The architecture of a plants root system will influence strongly these reinforcing properties. We explain how root morphology and biomechanics changes between species. An overview of vegetation effects on slope hydrology is given, along with an update on the use of models to predict the influence of vegetation on mechanical and hydrological properties of soil on slopes. In conclusion, the optimal root system types for improving slope stability are suggeste
