Earlier this season, Cohen & Master Arborist Tait Sala spoke with the CBC about the importance of advanced tree inspection techniques.
Visual inspections are the first step in assessing the health and structure of your tree, however in many cases our arborists will investigate further using next generation equipment to take calculated measurements of the tree’s strength.
We analyze this scientific data to determine the structural integrity of your tree and prescribe informed treatment strategies to keep your tree healthy, safe and beautiful.
What is a Sonic Tomograph?
A Sonic Tomograph is much like an ultrasound for trees. By placing a series of sensors around a trunk or branch, we are able to detect internal rot, cavities and cracks. A digital display allows us to see the percentage of sound stable wood remaining which is used to calculate the required strength needed to support a tree of that species, size and location.
What is Resi-Drilling?
Resistance drilling (Resi) will produce exact real time measurements of residual remaining holding wall thickness of a branch, tree trunk or even anchor roots. A digital drill drives a very thin drilling needle (1.5mm in diameter) into the tree, measuring the drilling resistance and feed speed curve to identify decay and other physical defects. The device produces a visual feed graph displaying precise location and thickness of sound stable wood.
Informed prescribed treatment
With these tools and data, your arborist can properly advise you on the state of your tree and will prepare a comprehensive treatment plan to reduce hazard potential and preserve your mature tree for decades to come.
