Abstract

Climate-induced stresses, more than in the past, expose trees to hazards possibly compromising their stability, with serious risk for people, objects, structures and infrastructures. In order to prevent trees falling phenomena, a constant improvement of the knowledge of relations between trees and meteorological events (trees-wind in particular) is crucial. Any new technology able to support research and monitoring in this direction must therefore be studied, tested, and finally adopted in order to create an infrastructure that would bring indisputable advantages from a social, economic and environmental point of view. The aim of this study is to test the applicability of GNSS receivers for monitoring wind-associated tree movements. The case study reported here refers to an experimental analysis carried out on an Italian stone pine (Pinus pinea L.). The analysis was carried out by applying a low-cost GNSS receiver at the top of the tree and evaluating the results obtained in term of velocities and positions (Mascitelli et al., 2018). Then, values obtained were correlated with wind characteristics. The experimentation was carried out through the use of a single frequency GNSS receiver, its autonomy and its low cost make this instrumental solution very competitive compared to others potentially usable for similar purposes. A sonic anemometer was installed very close to the pine tree (within 15 meters), in order to independently record the impacting wind fields (velocity, direction). This allowed us to study the correlation between the wind velocity (cause) and tree movements (effect).
