Visual Tree Assessment

• Visual Tree Assessment (VTA) is a visual tree safety check. This is a method to estimate the risk of trees in terms of:​

  • Stability: whether or not the tree falls.

  • Fragility: whether or not to break down the entire tree or parts of it.

​

​

• Itresult of this VTA is a classification of the inspected tree into one of the following classes:

  • No Increased Risk (GVR): with these trees the chance of causing damage or injury is virtually non-existent.​ This does not mean that there is no risk: even trees without visible defects can fall or break.

  • Increased Risk (VR): with these trees there is a real chance of causing damage or injury. Depending on the circumstances, you can then opt for:

    • Further investigation regarding specialist equipment. Based on this result, the trees are placed in the “Attention tree”, “take measures” or “felled” category.

    • Take action so that the tree no longer shows an increased risk.

    • Sheets

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