A Review of Sustainable Landscaping: Principles and Practices

This title provides a thorough overview of landscaping with sustainability as the emphasis. The first chapter sets the context, defining sustainability, giving a short history of the sustainability movement, and mentioning key scholars as well as first principles; as with medicine, the core concept is “do no harm”; another is “preservation, conservation, regeneration” (p. 4). The rules and function of a sustainability audit are given, as a setting can be examined and solutions developed to improve its ecological impact. Various chapters consider sites according to sun, water (both conservation and overabundance), and soil; and there are discussions of soil carbon, fertilization, building up organic matter, creating and using compost, phytoremediation, use of and precautions with pesticides and the like. Plants to use in landscaping are considered in terms of their needed maintenance as well as what structural effects they might have on the architectural and ecological context. Tables of beneficial and invasive trees, flowers and shrubs, and several lists of native species for specific purposes, such as attracting butterflies, are a useful inclusion. The water conservation chapter includes brief case studies from Colorado, Arizona, and California and the use of graywater for irrigation; and the section on dealing with flood amounts of water, with case studies from Ohio and Seattle, Washington, is particularly timely. The book could be easily used as a textbook for students in landscape architecture or horticulture, as the language, while professional, is not highly technical. Most terms are defined; there are numerous photographs, Tables, and line illustrations; and each chapter includes both learning objectives and end-of-chapter questions. None of the chapters covers any one topic in great detail, but sources are cited and there is enough information to let readers follow up if more depth is needed.
