Measuring and monitoring urban trees and urban forests

The urban forest includes diverse floristic and physiognomic plant communities, including trees, shrubs, herbaceous plants, and mosses. This chapter focuses solely on measuring and monitoring urban trees, rather than all plant communities within the urban forest. Urban trees can be classified into numerous groups including street trees, residential trees, park trees, and woodland trees. They may have been recently planted or they may be old-growth remnant forests on public or privately owned land.
