Healthy soil and other essential requirements are critical to the success of trees, but are often missing in the design concepts of contemporary urban landscapes. Up By Roots, written by James Urban, FASLA and published by the International Society for Arboriculture in 2008, is a manual for landscape architects, architects, urban foresters, and planners who are designing, specifying, installing and managing trees in the built environment.
Part One discusses basic soil science and tree biology and their relationship to healthy trees. Part Two explains the process of planning and implementing landscape designs to ensure healthy trees that can improve the quality of places where people live, work and play.
The book contains numerous illustrations and data in graphic form to provide guidance in the design of healthy soils and trees. Up by Roots was awarded the Honor Award in the Communication category by the American Society of Landscape Architects in 2009.
