Internal defects in trees compromise their capacity to perform ecological functions and maintain forest diversity. Therefore, monitoring the health condition of trees is important for the effective and sustainable management of forest and urban trees. In this study, a four-point electrical resistivity (ER) method was implemented to examine the health condition of Terminalia mantaly H. Perrier. Twenty standing samples of Terminalia mantaly with different trunk diameters were selected for this study. The electrical resistivities of the samples were measured using the four-point ER method, and the electrical resistance tomograms of the sampled trees were also produced to confirm the electrical resistivity measurements. A steady increase in ER from sapwood to heartwood was observed in healthy trees. However, unhealthy trees displayed resistivity anomaly, with decayed and hollowed trees exhibiting resistivity values six times lower and higher than those of healthy trees with similar diameters, respectively. Electrical resistance tomograms confirmed the results of the four-point ER technique. The outcome of this research would enhance efficient management practices and health condition evaluation of tree plantations in both forest and urban areas.
