Which of the following techniques is NOT considered advanced assessment?

Conducting visual tree inspections is a foundational technique in tree risk assessment and is not classified as an advanced assessment method. This basic approach involves visually evaluating a tree for visible signs of defects, such as cracks, decay, or structural issues without the need for specialized equipment or advanced techniques. It serves as an essential first step in the overall assessment process, enabling assessors to identify trees that may require further examination.

In contrast, using a probe to investigate cavities, employing thermal imaging, and utilizing resistograph measurements are all considered advanced techniques. These methods provide more detailed information regarding the internal condition of trees and involve specialized equipment and training. For instance, a probe can reveal the extent of decay within a tree, thermal imaging can detect temperature variations that indicate moisture levels or decay, and resistograph measurements assess the density of wood to identify structural integrity issues. Each of these advanced techniques enhances the accuracy of tree risk assessments beyond what a visual inspection could offer.
