The use of ground penetrating radar (GPR) to examine underground structures is now well developed. The use of GPR to map tree roots and to investigate the internal structure of tree stems is relatively recent. Arboricultural planning and risk management has been transformed. Rapid assessment of large areas is possible as is whole tree trunks in only a few minutes per stem. The use of radar for tree stems and for root mapping require slightly different methods and are normally undertaken for different reasons so the issues raised are discussed on separate pages as shown in the column on the left.
