Wind farms are an essential component of global renewable energy policy and the action to limit the effects of climate change. There is, however, considerable concern over the impacts of wind farms on wildlife, leading to a wide range of research and monitoring studies, a growing body of literature and several international conferences on the topic. This unique multi-volume work provides a comprehensive overview of the interactions between wind farms and wildlife. Volume 3 documents the current knowledge of the potential effects upon wildlife during both construction and operation of offshore wind farms. An introductory chapter on the nature of wind farms and the legislation surrounding them is followed by a series of in-depth chapters documenting effects on physical processes, atmosphere and ocean dynamics, seabed communities, fish, marine mammals, migratory birds and bats and seabirds. A synopsis of the known and potential effects of wind farms upon wildlife concludes the volume. The authors have been carefully selected from across the globe from the large number of academics, consultants and practitioners now engaged in wind farm studies, for their influential contribution to the science. Edited by Martin Perrow and with contributions by 30 leading researchers including: Göran Broström, Steven Degraer, Mike Elliot, Andrew Gill, Ommo Hüppop, Georg Nehls and Nicolas Vanermen. The authors represent a wide range of organisations and institutions including the Universities of Gothenburg, Hamburg and Hull, Alfred Wegener Institute, Cefas (UK), Research Institute for Nature and Forest (INBO), Royal Belgian Institute of Natural Sciences, Vattenfall and several leading consultancies. Each chapter includes informative figures, tables, colour photographs and detailed case studies, including some from invited authors to showcase exciting new research.
