Tree inventories are increasingly recognized as valuable tools by businesses, college campuses, cities, and other organizations. When managing a resource like trees, the first step is understanding what you have, which is exactly what a tree inventory provides. The depth of the inventory varies based on its purpose, but the basic function remains the same. 

How Tree Inventories Work

Most tree inventories begin by assigning each tree an identification number. This number is stamped on a metal tag and attached to the tree during the survey. A handheld computer captures the tree’s location and records other key data, such as: 

A professional tree inventory requires experienced arborists who can accurately identify species, assess tree health, diagnose problems, and recommend treatments. Arborists can perform inventories year-round, even during the winter months. 

Municipalities in Michigan were among the first to realize the importance of tree surveys. Early inventories were simple lists of numbers and columns. Today, thanks to advancements in software, GPS, and GIS technology, tree inventories have become interactive tools. They provide an overhead view of trees in relation to streets, buildings, and infrastructure, giving homeowners, land planners, and project managers a clearer perspective. 

Assessing Tree Value

Tree inventory data helps assess the financial value of trees, which often surprises property owners. Trees can be worth thousands or even millions of dollars, making a strong case for regular maintenance. For cities and private property owners alike, understanding tree value supports budgeting for proper care. 

Planning Maintenance with Tree Inventories

Tree inventories are essential for developing pruning or removal schedules. Knowing what trees you have and their condition allows for efficient planning and budgeting. Maintenance crews can use maps or GPS coordinates to locate specific trees that need attention, streamlining the process. 

A professional tree inventory gives land developers a bird’s-eye view of tree locations in relation to existing and planned infrastructure. This often results in better construction planning, reducing tree removal costs and preserving valuable trees that enhance the finished project’s value. 

Tree inventories also help developers avoid costly mitigation or easement fees by identifying alternatives that minimize tree removal and by flagging dead or diseased trees that shouldn’t be included in mitigation costs.
