Tomograph and resistograph are advanced technologies that inspect the internal health of urban trees and assess the risk of falling, without causing damage Disclosure/City Hall of Guarujá Two pieces of technological equipment began to be used in Guarujá, on the coast of São Paulo, to inspect the internal health of urban trees and assess the risk of falling without causing damage. The tomograph and resistograph are new tools in the municipality and provide a technical and scientific basis for determining whether a tree needs to be removed or whether it can be treated and preserved. The demonstration of the instruments was carried out last Tuesday (2), during a pruning action on Rua Benjamin Constant, in Pitangueiras, with the presence of Mayor Farid Madi. The equipment began to be used on the same day and will be used according to the technical need identified in each case. ✅Click here to follow the g1 Santos channel on WhatsApp. The service is developed by the Municipal Secretariat for the Environment and Climate Security (Semam) in partnership with the company Florestana, responsible for afforestation, pruning and tree maintenance services in the city. According to the city hall, the equipment is part of the existing contract with the company and is part of the services provided to the municipality. Now on g1 How does the equipment work? CT scanner: works as an “image exam” of the torso. Sensors are positioned around the tree and, upon receiving light knocks, measure the time it takes for the sound to travel through the wood. The software generates a visual map in two or three dimensions that indicates cavities, cracks and signs of internal deterioration. Resistograph: uses a fine needle that pierces the wood and measures its resistance. The device records, on a graph, the variation in effort required for drilling. High strength indicates healthy, dense wood, while low strength may reveal hollow or compromised areas. Ecological afforestation The technique adopted is ecological afforestation, which combines planning and management of trees in urban areas with a focus on conserving native biodiversity and the safety of the population. The mayor used the resistograph to measure the internal health of one of the trees and approved the equipment. "It is extremely necessary to take care of the green areas of Guarujá with care. The act of conservation and preservation is something that we must value, aiming for the quality of life and the future of planet earth", he stated. After carrying out the examinations, the data collected will be analyzed by the responsible technical sector, which will use the information to base decisions on the appropriate management of each tree. Based on the results, it will be possible to define whether the specimen needs removal, treatment or just preventive monitoring. VIDEOS: g1 in 1 minute Santos
