The historical context, the functioning of the drainage system and the nature conservation resource lay the foundation for this book. Contributions consider the ecology and methodology for describing and assessing this habitat, setting the scene for a number of chapters dealing with the different elements of flora and fauna, aquatic macrophytes, invertebrates, and birds of the channel and associated grassland habitat. The management of drainage channels for nature conservation is explored through a number of case studies around Europe and from Southern Africa and North America. These include weed control, the impact of pumped drainage and the drainage imperative in general. The book concludes by looking to the future of drainage channels and drainage systems. The book brings together many experts, from drainage engineer to ecologist, and ornithologist to botanist, and includes comprehensive case studies from diverse areas.
