Short summary
The approach we present has the potential to contribute to the understanding of several types of plant interactions such as coexistence, competition and niche extent. By combining geophysical exploration techniques GPR and ERT we provide experimental evidence of horizontal roots located under exfoliated rocks and in water reservoirs. We also study how the roots access water retained in the weathered rock during droughty periods and the implications for survival and coexistence of forest species.
