One of the more specialized services that Schneider Tree Care offers is Tree Risk Assessment.
This is a technical report that is written in order to give the tree owner a professional assessment of the current state of the risks associated with potential failure of the tree or trees in question.
A certified arborist qualified through the ISA (International Society of Arboriculture) in tree risk assessment will visit the property and assess the tree or trees that the tree owner has questions about.
The arborist will ask questions to the tree owner to determine several pieces of information, such as: How long has the tree been there? How long has the tree looked like it does in its current state? Has there been any construction on the property or near the tree? All these questions develop a history for the tree. Did you know that trees will exhibit signs of construction 5-10 years past the date of final construction? Details like this are helpful in establishing a framework for the tree, which will help with the final evaluation.
The arborist will look at the current state of the tree and take notes on his observations. How tall is the tree? What is the diameter of the tree? What is the condition of the trunk, crown, and roots? Is there a cavity on one side of the tree? The arborist can use specialized formulas to determine the amount of potential strength loss of the tree. A piece of equipment called a Resistograph can be used to measure the amount of internal decay. These measurements can also determine the amount of potential strength loss.
The report will also include recommendations for the homeowner to reduce the risks associated with the tree.
Once all the information is collected, the arborist will then write a report that details the findings while on site, as well as the professional opinions of the arborist about the current state of the tree. The report will also include recommendations for the homeowner to reduce the risks associated with the tree. Sometimes the recommendation is to remove the tree because the risk is too high due to decay or some other factor. Other times, the recommendations include cabling and/or bracing, soil therapy, pruning, growth regulators, borer spray programs, and many other things to help reduce the risk of potential hazards posed by the tree.
