Trees grow to maximize their access to sunlight. Without structural pruning early in life, this growth pattern can sometimes create structural flaws such as co-dominant stems and included bark. When these problems are detected early enough, pruning may solve the issue. When these trees are not pruned early and the defect becomes significant, hazard cabling and pruning may be sufficient to reduce the risk. In some cases, however, some trees are not candidates for cabling and tree removal is the only way to minimize the risk they pose.
In the last ten years, there has been a shift in cabling practices in this country. This can be attributed to the research in tree failure performed by the late Dr. Alex Shigo and Dr. Claus Mathett. Their research, as well as that of many others, has shown that the static loading caused by a rapid tensioning of steel cables in tree canopies can lead to structural failure.
In some cases, steel (static) cables are the best choice for the situation, but the majority of the time dynamic synthetic cables, properly installed with shock absorbers, are the better choice. Our certified arborists will determine the best cabling system and design appropriate for your situation.
