Ground Penetrating Radar
(GPR)

Ground Penetrating Radar (GPR) is a non-invasive technology used by arborists to evaluate and map tree root systems without disturbing the soil. GPR works by emitting high-frequency radar waves into the ground. As these waves travel through the soil, they reflect back when they encounter subsurface objects, such as tree roots, rocks, or other underground structures. The time it takes for the waves to return, along with their signal strength, helps create detailed images of root systems, indicating their location, depth, and density.

This technology is especially useful for root mapping, identifying root spread, and assessing root health while preserving the integrity of the surrounding soil. GPR can assess root systems near construction sites and aid in managing tree stability in urban settings. By providing clear data on the extent of root growth, arborists can make informed decisions regarding tree health and necessary interventions, making GPR an essential tool in modern tree management and preservation.
