In this study, the AA. evaluated the possibilities of using Electrical Resistivity Tomography (ERT) to measure soil moisture availability and plant water use in a Mediterranean natural area. They found that ERT is a useful tool for measuring soil conditions, providing information on the spatial patterns within the soil and reaching depths otherwise inaccessible. In heterogeneous soils, they differentiated between lithological and moisture effects in the measurements using multitemporal data. Based on the ERT measurements, they found that although the soils in the study area are shallow and rocky, plant roots penetrate deeply into the fractured and weathered bedrock, and vegetation subtracts water from depths down to 6 m and below. This information is important for understanding the plant-soil relations and modeling vegetation development
