Test Bore Evaluations

 

 

The role of an arborist is to care for trees and shrubs and provide the customer with information regarding their trees' health, safety and longevity.  Whether its identifying potential tree hazards, diagnosing a disease or recommending the proper type of pruning, we must first gather as much information as possible.

 

Sometimes, an evaluation can be a simple visual inspection.  However, in order to know what conditions exist within the interior of the tree's trunk and root flairs, we must perform a bore test.  Samples are taken from multiple sites throughout the trunk as well as the root flairs and are evaluated for decay or disease.  This enables us to approximate the extent of decay within the tree, so that we can make the proper recommendations.

 

It is not always obvious from the exterior that significant decay exists within the trunk of the tree.  And, a tree can appear to be completely healthy, despite having massive decay within its interior.  The information gathered from this test is valuable in that it exposes hazardous trees that might otherwise go unnoticed.
