Description: All trees pose some level of risk to nearby people, structures, and utilities. Typically, this risk is minimal and is far outweighed by the environmental, social, and economic benefits offered by the trees. As trees age or become weakened by pests, disease, and other stresses, this balance may shift, requiring a tree owner or manager to decide what risk level they are willing to accept and what modifications and actions may be needed.
