''Preliminary data of the effects of selected deep-rooted vegetation on the soil state: results from an in-situ test''

The use of novel naturalistic interventions making use of vegetation have been already proven to be successful in the reduction of erosion along sloping grounds, or in increasing the stability of the shallow covers of slopes, whereas the success of vegetation as slope stabilization measure still needs to be scientifically proven for slopes location of deep landslides, whose current activity is climate-induced, as frequent in the south-eastern Apennines. In this paper, preliminary field data representing the interaction of clayey soils with a selected vegetation species are presented and discussed. These have been logged within a full scale in-situ test site, where the deep-rooted crop spices have been seeded and farmed. The test site (approximative 2000 m2) has been set up in the toe area of the climate-induced Pisciolo landslide. The impact of the vegetation on the soil state is examined in terms of the spatial and temporal variation of the soil water content and suction from ground level down to depth, considering the interaction of the climate data recorded by a meteorological station, both inside and outside the vegetated test site.
