A street tree inventory is a project that unfolds in three practical stages: planning, implementation, and ongoing operations.

Planning sets up the project: it defines objectives, scope (which streets or areas to cover, what data to collect), data standards, methods, safety requirements, staffing, timeline, and budget. This stage ensures everyone agrees on what constitutes a complete inventory and how the data will be used.

Implementation is the hands-on data collection phase. This is where you survey streets, identify individual trees, record key attributes (species, diameter at breast height, condition, location), tag trees as needed, capture GPS coordinates or mapping data, and input information into the inventory system. Emphasis is on accuracy, consistency, and data quality during this fieldwork.

Operational use follows, applying the inventory data to day-to-day street tree management. This includes generating maintenance schedules, prioritizing pruning or removal, planning replacements, tracking changes over time, and producing reports for stakeholders. The data become a living asset that guides decisions and is regularly updated as trees grow, die, or are added.

Other options describe related activities but not the lifecycle of compiling and using a street tree inventory.
