Melinda's Garden Moment: Getting a look inside your trees

Posted: Updated:

MADISON (WKOW) -- Seemingly healthy trees can fail.  Once the tree is removed, a hollow center reveals the cause of the tree failure.

Arborists have a minimally invasive tool that helps diagnose the soundness of a tree.  This information can help them diagnose tree problems and reduce the risk of unexpected tree failures that create a hazard for people and property.

An electric high-resolution needle drill makes a fine hole in the tree. As it travels through the trunk it measures the resistance encountered.   A pint out is produced mapping out the internal structure of the tree.

Arborists use the results of this measuring tool to get a look inside sick and declining trees.  These test results can help them determine if a tree is a hazard and should be removed or one that can be saved.
