Although trees have been an important part of human settlements throughout history, only recently has their full value to urban dwellers been recognized. Trees and green spaces play an important role in improving city living conditions. In the past, urban forestry in developed countries was considered almost exclusively on the basis of its aesthetic merits. Now, a closer look is being given to the environmental services and quantifiable economic benefits they provide. This article discusses the role of trees in and around densely populated areas.
Urban forestry has as its objective the cultivation and management of trees for their present and potential contribution to the environmental, social, and economic well-being of urban society. Urban forestry is a merging of arboriculture, ornamental horticulture and forest management. It is closely related to landscape architecture and park management. In its broadest sense, urban forestry embraces a multifaceted managerial system that includes municipal watersheds, wildlife habitats, outdoor recreation opportunities, landscape design, recycling of municipal wastes, tree care and the production of wood as a raw material.
