The foundation of an effective urban forest management program is a detailed tree inventory. A tree inventory provides information such as tree health, species, size and location; this information is used to generate reports that can help urban foresters in their strategic planning. Inventory data can be used to identify species diversity and distribution, percentage of canopy cover, size/class distribution, etc. Coupled with an inventory, a tree inspection cycle is integral for proper tree maintenance and hazard abatement. Effective tree monitoring enables park managers, urban foresters and planners to evaluate the urban forest resource and develop short and long-term initiatives which can in turn provide substantial cost savings and mitigate safety issues.
