This book is intended for those with an academic, scientific and practical interest in river conservation and management. It provides an overview of how changes in legislation, policies, institutional responsibilities, science, technology, practical techniques and public perception have influenced how rivers have been managed over the past 20 years and the challenges that lie ahead during the next 20 years. The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South America, Europe, Asia and Australasia provide a wide-ranging perspective on this complex but profoundly important subject. Following an introduction that chronicles the most important contextual changes, the book is organized into four broad topics: Catchment management, ecosystem integrity and the threats to river ecosystems – this covers progress on understanding and addressing the pressures affecting rivers, many of which will be amplified by climate change and increasing human demands for water;Methods and approaches – illustrating some recent techniques that have been developed to assess condition and conservation status across different types of river;Recovery and rehabilitation – providing an insight into the principles, practice, public involvement and institutional networks that support and make improvements to modified river reaches;Integrating nature conservation into wider river management –demonstrating the importance of integrated planning, involvement of local communities and the use of adaptive management in achieving multiple environmental and economic benefits along rivers used for different purposes.The final chapter discusses the challenges faced in dealing with an uncertain future.More than 1200 different references and numerous web-site citations provide the reader with an invaluable source of knowledge on the subject area.

Throughout British history rivers have been of profound economic, social and cultural importance – yet as we see with increasing frequency they have the potential to wreak great destruction. This book describes the natural and not-so-natural changes that have affected British rivers since the last ice age and looks at the many plants and animals that live along, above and within them. Detailed case studies of the Meon, Dee and Endrick illustrate the incredibly varied nature of our river ecosystems, and the natural and human factors that make each one different. Written by two widely respected river ecologists, the book looks not only at rivers as they were and are but also at how they can be managed and cared for. Full of interesting facts and stunning images, Rivers is essential reading for anyone professionally involved in rivers and for the naturalist, conservationist and layman alike. It is the one book you need to understand this singularly important and often contentious feature of the British landscape.
