Description :
The aim of this paper is to evaluate and compare the suitability for preventing surficial landslides referred as miniature debris flows (MDF) of 6 dominant species at the juvenile stage, growing on marly slopes. Juvenile individuals of each species (tree, shrubby, herbaceous) were collected on site and the AA. measured root tensile strength and root system distribution with depth. Their contribution to slope stability was calculated using Wu's reinforcement model and their suitability for erosion control was assessed. The study site is located in the Saignon catchment, situated in North-East of Sisteron (Alpes-de-Haute-Provence department, France), a gully catchment on marls.
