As trees age, they become more susceptible to wood decay and other defects. Many old trees gradually fall apart before they decline and die. We can identify symptoms of decay and other defects such as weakly attached branches, cracks, and splits indicating possible failure, poor architecture, dead and hanging branches, and root related defects.
If evaluation indicates the tree shows a high risk of failure, remedial treatments can be developed to reduce that risk. Treatments could involve pruning to reduce branch weight and wind resistance. When treatments will not reduce the risk of failure to an acceptable level, tree removal or restricting access to the area near the tree must be considered to prevent personal injury and property damage.
