A Certified Arborist can often determine if a tree is a potential hazard by examining the tree and the site. Looking from the ground is not always enough. Getting a view from the crown of the tree may be necessary, requiring a climbing crew or the aid of an aerial lift truck. In some cases decay is apparent; however it is impossible to determine the extent of decay solely by the appearance of the tree. When our Arborists are concerned about the extent of decay in a tree and cannot determine this by visual inspection, we use a tool called a Resistograph.

Through analysis of this data, we can accurately measure the amount of decay in a tree and provide the client a proper hazard evaluation. In the past, trees thought to be hazardous were often removed only to find minimal amounts of decay.
