What is the function of a "decay detection tool"?

The function of a "decay detection tool" is to assess the internal condition of a tree for decay. These tools are specifically designed to help arborists and tree care professionals identify areas within a tree that may be suffering from fungal decay or structural weaknesses. By using a decay detection tool, such as a resistograph or sonic tomography, professionals can gain insights into the health of the tree beyond what is visible externally. This is crucial for making informed decisions about the tree's safety and longevity.

The assessment provided by these tools is essential for risk assessment because many trees may appear healthy from the outside but could be compromised internally. Understanding the extent and location of decay helps in planning appropriate management actions, such as pruning or determining if removal is necessary to prevent potential hazards.

While other options touch on aspects related to trees, they do not relate to the specific and crucial role that decay detection tools play in evaluating the internal health of a tree.
