Finally, in the realm of landscape maintenance, ensuring that trees are healthy is often a tricky and costly business, and as more and more areas become built up, trees become more valued as an environmental asset. Enter Cohen & Master Tree and Shrub Services Ltd., which has always placed great importance on a proactive method of tree care. "Most recently we took big steps in analyzing and evaluating mature trees with specialized equipment known as Sonic Tomography and Resistograph drilling," says Cohen & Master director Tait Sala. Sala goes on to explain this relatively new deployment of technology in North America is an advanced level of tree inspection. "The thing about mature trees, especially in urban areas, is that the outer wood can cover old injuries and defects. With Sonic Tomography we place sensors around the trunk and pen- etrate it with sound waves, and the rate by which they penetrate reveals defects." With Resistograph drilling, a digital drill with a very fine bit penetrates the tree, and fluctuations in the velocity of the bit reveals defects and decay. "By overlaying the data from both devices we can learn a lot about what's going on, and we've saved a lot of heritage trees in this manner that may look damaged on the outside due to lightning strikes or other phenomena but are in fact sound on the inside," Sala says. Sala adds, "The information allows us to make critical decisions about vital preservation and retrenchment pruning and or tree removal when the defect and level of risk are too high. This is the future of advanced level tree assessment, and we're excited about spearheading a science-based approach to preserving the urban canopy." A Mature tree inspection using Sonic Tomography.
