    Using Appraised Values of Trees to Make Urban Forestry Management Decisions: Is a Tree Worth the Cost of Maintenance?


    Decisions for budgeting and spending money on maintaining trees can have an economic basis. When evaluating trees on a property, whether across a city's urban forest, trees in mall parking lots, or trees in a private yard, calculating the value of the trees can help in decisions.
    To prioritize maintenance, it helps to know that the trees at the main entrance of a park have a higher value than the trees in the natural area in the back corner. Knowing a tree has a current value of $1,200, when the necessary pruning and pest control work for structure and health will cost $900, can direct decisions for when the tree is worth the work to maintain it.
    In this session we will review the results of tree inventories and tree value calculations for a city park, a commercial property, and a homeowners association. Knowing the tree values helped the decision makers to best prioritize their budgets, while providing increases in tree values with the results of the maintenance work completed.
    Take home lessons include: The data to collect when doing a tree inventory or tree evaluations to make economic decisions about trees, decision making for tree maintenance using tree values and maintenance costs, and showing how tree maintenance improves current tree values and tree health.
