Picus Sonic Tomograph

~ Monday, 18th July 2011

We have found our Picus Sonic Tomograph to be one of the most useful tools we have when inspecting and risk-assessing mature trees.

The device works by measuring the relative speed of sound waves propagated through a tree stem, and produces a full-colour, 2D sectional image, non-invasively. 

We have undertaken Picus surveys for the National Trust Wales, Gwynedd Council, Tarmaster Jones Architect, Ysgol Dyffryn Conwy and a range of private clients.

Details of how the system works can be found at: www.argus-electronic.de/index.php/en/picus-sonic-tomograph and an example of research relating to this device can be found here: www.treelink.org/joa/2004/sep/gilbert9-04.pdf

We have found that having this additional set of data allows us to make a far more nuanced and precise prescription for the management of mature trees in built-up areas.
