A root mapping assessment is a process that involves locating and mapping the underground roots of trees. It helps identify the extent and distribution of tree roots, which is crucial for planning construction projects and ensuring the protection of trees during development. Root mapping assessments are typically conducted using specialized equipment and techniques, such as ground-penetrating radar or air excavation. The collected data from the assessment can inform decisions on tree protection zones, root pruning, and other measures to minimize impact on tree roots.
