Which types of data are typically collected in a tree inventory?

In a tree inventory, diameter, location, condition codes, and maintenance codes are essential types of data collected.

Diameter is a crucial measurement as it helps determine a tree's health, age, and growth potential. It also plays a significant role in calculating the tree's biomass and the ecosystem services it provides. The location data is vital for managing and planning tree care, assessing the landscape's ecological value, and creating maps for future reference and maintenance.

Condition codes provide quick insights into the health and structural integrity of the trees, indicating whether they require immediate attention or ongoing monitoring. Maintenance codes help track the work completed or required for each tree, facilitating better management and care strategies.

While the other answer choices include valuable information related to trees, they do not encompass the standard, practical data typically focused on in tree inventories. For example, while species, height, and growth rate are important, age is often more difficult to ascertain accurately in the field. Root depth and crown spread offer insight into tree health and structure, but again, they are not standard inventory data. Understanding soil type and moisture levels are more related to site assessment rather than the individual tree inventory. Thus, the combination of diameter, location, condition, and maintenance codes represents the most relevant and
