Tree Acoustic Tomography

Tree acoustic tomography is a non-invasive and innovative method used to assess the internal health and structural integrity of standing trees. It relies on the principle that stress waves travel at different speeds through various materials, such as wood, air, and decayed or hollow areas within a tree trunk. This technology involves specialised equipment, typically including a set of sensors attached to the surface of the trunk at a certain height. Acoustic pulses are sent into the tree, and by measuring the time it takes for the sound waves to bounce back and analysing their characteristics, arborists and researchers can create a 2D image reconstruction of the tree's interior state of a specific cross-section. This information helps identify potential issues like decay, cavities, or structural weaknesses, allowing for more informed decisions about tree management, preservation, or removal. Tree acoustic tomography has gained popularity in urban forestry and arboriculture as it provides a non-destructive and efficient means of evaluating tree health and safety. By creating a visual map of a tree's internal structure, it enables professionals to make informed decisions about pruning, supports systems, or whether a tree poses a hazard to its surroundings. Additionally, the technology has the potential to contribute to the preservation of old and valuable trees, as it allows for targeted interventions based on the specific condition of each tree, ultimately promoting the longevity and safety of urban and natural tree populations.
