This volume reviews the current scientific knowledge of wetland restoration, identifying the problems and opportunities associated with it. Based on revised and edited contributions to the recent Restoration of Temperate Wetlands symposium, it provides a broad overview of current information and experience of wetland restoration. In some cases it highlights the lack of knowledge available and illustrates how difficult it can be to make informed decisions. With contributions from Scandinavia, Europe, Australia, the USA and Canada, outlining the latest research and observations from a range of international wetland scientists and practitioners, this book provides a critical review of current information and knowledge and gives insights into many aspects of wetland restoration, with a focused approach to the ecological principles that underpin it.
