Photogrammetric 3D documentation

Basal decay and loss of structural wood.

This 3D model depicts the root flare and lower stem of a mature pin oak with extensive basal deterioration. The tree had lost approximately 80–90% of its basal wood, materially reducing structural capacity at the point where loads are transferred into the root system.

Select the viewer to load the model. Drag to rotate and zoom to examine the remaining structure.

Interactive models like this can help illustrate the extent and distribution of decay, buttress loss, and remaining shell thickness in a way that standard photographs often cannot. In forensic arboriculture, this type of visual evidence may assist in explaining condition, defect severity, and failure potential to attorneys, insurers, mediators, and juries.

Illustrative model shown for educational and demonstrative purposes.
