Visual Tree Assessment

Visual Tree Assessment (VTA) is a visual tree safety inspection. This method is used to assess the risk of trees in terms of:

• Stability : whether or not the tree will fall.

• Susceptibility to breakage : whether or not the entire tree or parts of it break off.

The result of this VTA is a classification of the inspected tree into one of the following classes:

• No Increased Risk (GVR) : These trees pose virtually no risk of causing damage or injury. This doesn't mean there's no risk: even trees without visible defects can fall or break.

• Increased Risk (RR) : These trees pose a real risk of causing damage or injury. Depending on the circumstances, the following options may be considered:

  • Further research regarding specialized equipment. Based on this result, the trees are categorized as "Attention Tree," "Take Action," or "Cut."

  • Take measures to ensure that the tree no longer presents an increased risk.

  • Sheets

• Attention tree : these trees have a visible defect that does not yet pose an increased risk.
