Tree Assessment Service Columbia South Carolina
What is tree assessment?
Tree assessment simply refers to the steps and procedures taken to identify and evaluate trees for traces of failure and abnormalities and or weaknesses. Periodic and constant tree assessment is necessary for the early discovery and identification of pests, diseases and faults in trees. It is a very skilled procedure and requires the service of professional arborists or Tree care Services. This is a great way to make sure that you and your family are safe all year round no matter what. We will come out and evaluate the problem trees and make a professional decision about what to do. Our team are all trained arborists that are highly skilled and are able to make the right call when necessary.
How Do Tree Assessments Works?
There are various methods used in accessing trees for risks; they include
Basic method: The basic tree assessment method involves a concise and detailed examination of the tree and the vegetation around it. Tools like a mallet, binoculars, and shovels are employed in carrying out analysis. The results caused by this form of assessment are quite reliable as they provide a thorough investigation of the tree.
During the examination, professionals look out for defects that are large enough to cause severe problems to the tree's health. Professionals make use of factors such as load targets and health to make their conclusions. Compared to other alternatives, this method is not effective as it only gives little information about underground tree parts. It can be quite challenging to evaluate defects that occur at the upper crown of the tree. The difficulty encountered is due to the simplicity of signs and symptoms used for evaluation.
Advanced method: Due to the uncertainties associated with risk assessment using the basic technique, many questions are often left unanswered. Now, the advanced approach is used to answer these questions. The advanced process involves aerial inspection with a bucket truck, examination, and measurement of the extent of decay observed on trees, an excavation of the rich crown with an air tool. This method provides more details into the observed effects on trees.
Other techniques applied in the advanced process include load testing, where a detailed and objective picture taking from a tree is analyzed. Sometimes multiple images need to be taken to obtain more accurate results, especially when the tree being observed is difficult/complicated. Advanced tree analysis is more expensive than the basic analysis. The data interpretation is carried out by a professional whose judgment is used as a recommendation for four clients.
ISA Tree Hazard Evaluation: Matheny and Clark developed this method of tree assessment in the year 1994. It is arguably the most use of all the three methods listed here. Here, risk assessment is broken into three parts: the failure potential, size of the region, and target rating. These various sections are assigned values between 1 and 4. The combined value of the scores obtained by a tree on all three sections is called a hazard rating. A hazard rating above 12 is considered a severe hazard, while a rating below three is considered the least occurring hazard.
This method is used to identify and classify hazards based on their degree of severity to determine an appropriate action to enforce. Due to the limitations of this method, it is mostly applied in a modified form. A comparative analysis is carried out when assessment is done between a group of trees. The procedure is quite different for observations made on single trees.
