TL;DR
A tree risk assessment is a systematic evaluation of the likelihood that a tree or its parts will fail, strike a target such as a house, driveway, or play area, and cause consequences, combined into a risk rating that guides what to do. Credentialed arborists follow the ISA's TRAQ methodology, working from visual inspection of defects like decay columns, cracks, root damage, and lean, escalating to sonic tomography or resistance drilling when the interior matters.
