What type of inventory collects data about individual trees?

The correct choice, which focuses on collecting data about individual trees, is a tree inventory. This type of inventory is designed specifically to assess and document the characteristics of trees within a particular area. It typically includes details such as species, size, age, condition, location, and health status of each tree. This comprehensive data collection is crucial for urban forest management, planning, and maintenance, allowing municipalities to make informed decisions regarding tree care, risk assessment, and preservation strategies.

Natural resource inventories often encompass a broader range of environmental features, including flora and fauna, while species inventories may concentrate on cataloging various species present in an area but do not provide specific information on individual trees. A landscape inventory typically assesses larger areas and features, such as land use and open space, rather than focusing solely on the specifics of individual trees. Thus, the specificity and targeted nature of a tree inventory make it the correct answer for collecting data about individual trees.
