Roger Greenwood
The benefits of trees in the urban environment are huge and with the ever increasing size and density of our cities trees are becoming both more important and more at risk than ever before.
Working in trees has given me a deep appreciation of the wonder of trees and my further education and later career in consulting has expanded my knowledge of trees and their management within the urban environment.
Trees are, in my opinion, one of the main redeeming features of the urban environment and their preservation and care within this rapidly changing ecosystem is my primary professional interest.
Since commencing in arboriculture in 1985 I have developed an abiding interest in the role of trees and the urban forest in our cities and towns.
