Here are some pictures from the bracing and cabling course I took part this week.
Trees can grow in such a manner that their physical structure can no longer support their own weight. This is particularly common in mature multi-stemmed trees and trees with open canopies. Failure of a large branch can result in property damage, personal injury, or the decline in the trees health. Cables and bracing rods are tools arborists use to protect or improve the structural integrity of trees.
The installation of cables and bracing rods,along with pruning to reduce end-weight can reduce the likelihood of a structural failure. Properly installed cables help to redistribute structural stress, and bracing rods can provide support to branch attachments deemed weak.
