Accurate and rapid decay detection is a key element in saving trees from unnecessary felling, saving costs and minimising liabilities. We operate one of the few 'Picus' Sonic Tomographs with calliper systems in Scotland. This new technology from Germany is able to 'see' inside the tree and calculate the extent of decay, without the need for the intrusive or invasive techniques required by other methods.
Most commonly, trees are damaged or require to be felled because of decay by fungal infections. The leading edge technology in the Picus Sonic Tomograph measures the structural integrity of a tree and the extent of these infections. The principle behind the technology is that uninfected wood is a better sound conductor than wood damaged by decay - and therefore sound waves can be used to generate two dimensional pictures of the tree's core. Magnetic sensors are wrapped around the tree and each sensor measures the velocity of the sound waves. Any decay or cavities can be easily and accurately detected.

The Picus Sonic Tomograph is an extremely important tool in the evaluating tree decay and identifying potential hazards. It has been instrumental in saving a number of valuable amenity and heritage trees from needless felling. As a consequence it saves clients money and mitigates the risk of damages, liabilities or legal actions arising from hazardous trees.
