Tree Inventories

摘要

A tree inventory is a record of the attributes (location and characteristics) of individual trees within a defined geographic area. However, the scale and complexity of inventories vary with the specific needs, goals, and resources of the local context. The premise for a tree inventory is that trees are infrastructure, and should be managed as such.Conceptually, every inventory involves features, attributes, and values:Features are the items that are inventoried—in the case of tree inventories, trees or sites. Examples of other features that can be inventoried include utility wires and poles, shrubs, putting greens, irrigation systems, planting-strip width, and hardscape (e.g., fountains, walks).Attributes are the qualities or characteristics of a feature that will be recorded during the inventory process. Attributes can be broadly divided into two types of data: 1) location information and 2) tree characteristic information. Attribute information often collected during inventories includes tree species, diameter, and condition.
