Green roofs are a hot topic, and one that constitutes a trend extending well beyond the world of gardening. This sourcebook brings together a fascinating amount of data, covering the actual logistics of how to implement plantings on roofs and building facades. Dunnett and Kingsbury look at examples of ornamental projects while stressing the concept's solid link to the environment. Examinations of recent research underline the wide-ranging benefits of greening buildings, from recreational aspects to increased energy efficiency. Among the most positive changes to emerge are improvements in the air we breathe and the support of biodiversity. Given the lively current interest in how to extend living ecosystems that reach beyond the ground plane to the upper stories of our homes and office buildings, this resource offers important technical advice, along with horticultural recommendations pertinent to flat or sloped roofs and the greening of vertical surfaces. Undoubtedly, other manuals will appear as an interest in living roofs increases. At present, the material compiled here will be welcomed by a wide audience. Alice Joyce
