Key message
Visual inspection parameters for predicting the risk of urban trees falling match the actual internal condition of the stem, as well as the results of tomograms (SoT and ERT).
Abstract
Eliminating the risk of tree falls in urban areas is economically and technically unfeasible. Effective management requires reliable tools to guide interventions and maximize urban forest benefits. This study examined the relationship between visual analysis and the internal condition of Spathodea campanulata trunks, using sonic (SoT) and electrical resistance (ERT) tomograms. The trunk sections from 30 removed trees at UFV (Viçosa-MG) were analyzed. The cavities appeared in 26.7% of cases, cracks in 20%, and wood deterioration in 10%. Tomograms aligned with cutting results in 70% of cases, with sonic tomography being easier for cavity detection and electrical tomography more accurate for wood deterioration. It was not possible to define a visual analysis methodology with association with the problems evidenced in the section. Combining tomographic and visual inspections enhances tree fall risk assessments.
期刊介绍：
Trees - Structure and Function publishes original articles on the physiology, biochemistry, functional anatomy, structure and ecology of trees and other woody plants. Also presented are articles concerned with pathology and technological problems, when they contribute to the basic understanding of structure and function of trees. In addition to original articles and short communications, the journal publishes reviews on selected topics concerning the structure and function of trees.
