Predictive models are important tools not only for managers of urban street tree planting programs, but also for designers of urban infrastructure. Urban infrastructure often has elements that include restricted planting spaces, and ability to predict the Trunk Flare Diameter (TFD) of a mature tree can assist urban planners and natural resource managers in designing appropriate sites or selecting appropriate trees.
Trunk Flare Diameter estimates can also be used to regenerate a list of stumps for removal. If you know the species and DBH of a tree that was cut-down, stump size at ground-line can be estimated using the calculator or the downloadable Excel based calculator.

Prediction of TFD has several potentially useful applications for urban planners and managers of urban street trees.
