Tree risk should be assessed by an experienced arborist.
As an ISA Certified Arborist since 1993, I have knowledge and experience in tree risk assessment and make recommendations for tree risk abatement.
A tree risk assessment will identify structural defects and recommend an abatement procedure to minimize a potential of failure where damage could occur to people, property, and utilities, including obstructing traffic of roadways and railways.
Trees with co-dominant and multi stems may have a weak attachment between the main stems, predisposing them to failure. Mushrooms, conks, cavities, cracks and bark peeling are a few indicators of decay jeopardizing the structural integrity of a tree. Decay in the root crown and other areas can be hidden and require more extensive procedures to determine the extent of decay.
