Tree Risk Assessment in the Digital Age

0 comments


I have been using the IML Resistograph for ten years. In fact, I purchased one of the first instruments sold in the US. This tool has helped me to save many significant trees and make confident recommendations for removal of hazardous trees. The IML Resistograph is especially valuable in situations where the tree defect is located high in the canopy or below ground. I am a cautious and conscientious arborist, not one to drill holes in trees without good reason. When I am looking at a questionable tree, I need accurate information about the hidden cavities.
With the IML Resistograph, I can collect accurate data and clearly communicate the results to the tree owners or other interested parties. Currently there is a great demand for tools to evaluate defective trees that may result in personal injury/property damage.

I fully expect to see many tools for evaluating tree condition on the market in the future. Based on my experience so far, I am confident the IML Resistograph drill will continue to be a valuable tool that won’t gather dust in my closet!

Pole Inspection

The IML Resistograph is revolutionizing the utility pole inspection industry. Utility poles require regular inspections to evaluate the quality of the timber and level of wood decay present in determining whether the pole should be replaced. Most pole inspection services use primitive techniques that do not measure or record wood decay. More sophisticated procedures are needed to gather accurate data to assess a pole’s life span.

Pole Inspection Below Ground

The IML Resistograph provides an exact measurement of the current condition of the inspected utility pole. The instrument is positioned at the base to measure wood decay at ground level. The inspector then attaches the 45 degree adapter to measure and record the wood density below ground level. With this technology, digging is no longer required and many times, costly reinforcement of the pole is avoided.
