With more than half of the world's population now living in urban areas, it is vitally important that towns and cities are healthy places to live. The principal aim of this book is to synthesize the disparate literature on the use of vegetation in the built environment and its multifunctional benefits to humans. The author reviews issues such as: contact with wildlife and its immediate and long-term effects on psychological and physical wellbeing; the role of vegetation in removing health-damaging pollutants from the air; green roofs and green walls, which provide insulation, reduce energy use and decrease the carbon footprint of buildings; and structural vegetation such as street trees, providing shading and air circulation whilst also helping to stop flash-floods through surface drainage. Examples are used throughout to illustrate the practical use of vegetation to improve the urban environment and deliver ecosystem services.Whilst the underlying theme is the value of biodiversity, the emphasis is less on existing high-value green spaces (such as nature reserves, parks and gardens), than on the sealed surfaces of urban areas (building surfaces, roads, car parks, plazas, etc.). The book shows how these, and the spaces they encapsulate, can be modified to meet current and future environmental challenges including climate change. The value of existing green space is also covered to provide a comprehensive textbook of international relevance.

Hedges and field margins are important wildlife habitats and deliver a range of ecosystem services, and their value is increasingly recognised by ecologists. This book reviews and assesses the current state of research on hedgerows and associated field margins. With the intensification of agriculture in the second half of the last century, field sizes were increased by amalgamation and the rooting out of hedges, synthetic pesticide and inorganic fertiliser use increased, and traditional methods of hedge management were largely abandoned. The book is split into two main sections. The first deals with definitions, current and historic management, the impact of pesticides, the decline in hedge stock and condition, and new approaches to hedge evaluation using remote sensing techniques. The second section explores the pollination and biological pest control benefits provided by hedges and field margins and examines the ecology of some of the major groups that are found in hedgerows and field margins: butterflies and moths, carabid beetles, mammals, and birds. A case study on birds and invertebrates from a research farm managed as a commercial enterprise, but which attempts to farm with wildlife in mind, brings these themes together. A final chapter introduces the neglected area of hedges in the urban environment.The book will be of great interest to advanced students, researchers and professionals in ecology, agriculture, wildlife conservation, natural history, landscape, environmental and land management.
