Concerned that a tree may have internal decay, cavities or structural defects that cannot be seen from the outside? Request a PiCUS Tree Assessment today.
PiCUS vs Visual Tree Inspection
A visual inspection is an essential part of tree assessment, but some internal defects cannot be reliably identified from external symptoms alone. PiCUS Sonic Tomography can provide additional diagnostic information by investigating a cross-section of the tree stem.
When Might PiCUS Testing Be Recommended?
PiCUS Sonic Tomography may be appropriate when a tree presents signs that require more detailed investigation. Examples include: mature & veteran trees, suspected internal decay, high value trees, trees near buildings & public areas and trees with visible defects.
Detailed Investigation Avoiding Tree Removal
When internal decay is suspected, removing a tree isn't always the only option. For valuable, mature or important trees, further investigation may help establish the extent and location of internal defects before decisions are made about future management.

Make Better-Informed Tree Management Decisions
When a tree has suspected internal defects, making a decision based solely on what can be seen externally may not provide the complete picture.
Specialist diagnostic testing can provide additional evidence to support professional tree management.
Depending on the findings and wider assessment, possible recommendations may include:
Continued retention and monitoring
Further investigation
Targeted tree work
Structural management
Additional diagnostic assessment
Tree removal where justified by the overall assessment
Every tree and site is different, so recommendations should be based on the individual circumstances.
Frequently asked questions
What can PiCUS Sonic Tomography detect?
PiCUS Sonic Tomography can help identify variations within the tested cross-section of a tree that may be associated with decay, cavities or changes in wood structure. Results should be interpreted alongside a professional visual assessment and other relevant information.
Is PiCUS Sonic Tomography harmful to trees?
The technique is considered minimally invasive. Small sensors or probes are used at selected points around the stem to collect sonic measurements. The testing method and number of measurement points should be determined by a suitably trained professional based on the individual tree.
Does PiCUS testing tell you whether a tree is safe?
PiCUS testing provides diagnostic information about the tested section of a tree, but it does not by itself provide a simple "safe" or "unsafe" answer. The results need to be interpreted alongside the tree's overall condition, structure, defects, location and potential targets. A qualified tree professional can then make appropriate management recommendations.
