Dangerous trees can be obvious sometimes, but many times they require a trained and experienced eye to diagnose.
An experienced arborist is taught how to determine if a tree offers an increased risk of failure based on its size, branching structure, level of decay or damage, degree of lean, evidence of disease and many other considerations.
Removal of dangerous trees is a specialty far different from the removal of a healthy tree.
Experience is paramount when deciding who to trust with the removal of a dangerous tree.
One Two Tree has 30 years of experience as a company and well over 100 years of combined experience between the owner/arborist, the tree division manager/arborist and 3 tree crew foreman/professional trimmers (all with the company for over 16 years each).
A well thought out, safe strategy, on what method of felling and which equipment is needed is critical . Knowing where to cut, when to cut, how a tree will react when it is cut all comes from experience.
Some trees are too large, heavy, located or positioned such that the only safe method of removal is to involve a crane. Even the decision of how and where to position a crane can be very important. Being able to determine distance in reach Vs. weight being lifted is an expert skill. Predicting the reaction of the cut piece of a dangerous tree as it separates and “swings” away from its host is a very important aspect of a crane removal.
In the video clip you will notice how the professional trimmer notches the tree trunk on a Norfolk Island Pine tree that is over 100’ tall, at differing angles so that the crane operator can snap the “hinge” left by the trimmer, allowing ample time for the trimmer to safely move out of the way as the cut section is lowered to the ground.
