In that sense, the combined approach presented in this paper can be considered as a valuable tool for land-use planners and emergency cells in charge of forecasting future events and in protecting people and their assets from the negative effects of landslides.

In landslide prone areas, tree roots resist tension, thereby increasing the shear strength of shallow soils through mechanical reinforcement (Shewbridge and Sitar, 1989; Skaugset, 1997).B: View of the main scarp (SC1, dotted line) and of the landslide body.C: DB is characterized by shallow rotational slides in its upper part.The purpose of this study is to explore and illustrate the potential of exposed roots to reconstruct larger-scale landslide activity and thus to complement tree-ring data gathered from stems to reconstruct spatio-temporal patterns of landslide reactivation.Work was undertaken in a forested area of the Davids-Bas landslide, Barcelonnette (Southeastern French Alps) and based on growth disturbances (GD) from 48 stems and on anatomical changes (decrease of cell lumina) in 20 exposed root sections of heavily affected Mountain pine ( Mill.
