It is important to monitor the health of these tree and hedgerows, particularly in urban areas.

This helps us to spot signs of disease, as well as to identify opportunities to improve our management of these habitats for wildlife.

This catalogue includes ID guides for trees and hedgerows, and survey methods for beginners and those with a little more experience.
