Tree Stability Evaluation: the Importance of Monitoring Programs

none5One of the main issues in tree stability evaluations is the scheduling of adequate monitoring programs. Generally, after a tree analysis, an arborist indicates the required maintenance operations and the timing for periodical inspection. Field conditions, tree species and biomechanical defects influence the plan. Three old trees (Populus spp. and Celtis australis) located within Golf Club Verona (Sommacampagna, Italy) were monitored periodically from 2010 to present. In addition to visual assessment, authors used sonic tomography to evaluate development of internal defects and planning the maintenance. The aim of this work is to identify a methodology for observing significant difference in tomograms, in order to understand the appropriate interval between instrumental analyses.openMinelli, Alberto; Laura, Cevenini; Matteo, Corradini; Ilaria, Pasini; Daniele, ZuffaMinelli, Alberto; Laura, Cevenini; Matteo, Corradini; Ilaria, Pasini; Daniele, Zuff
