This book brings together research into the process of stream acidification and its impact on Welsh surface waters, carried out over the past decade or so. It is perhaps surprising that not until the 1980's was clear evidence of stream acidification assembled. In Wales, concerns over pollution had focused water quality sampling principally on the areas of traditional heavy industry and large urban popula tions served by inadequate sewerage systems and sewage disposal arrange ments. Mistakenly, it had been assumed that, with its prevailing westerly winds, Wales would receive precipitation substantially unpolluted by the industrial and urban emissions from Britain and mainland Europe. Assurance of the high quality of Welsh upland streams, the traditional nursery ground of salmonids, was eroded particularly by studies in the vicinity of Llyn Brianne reservoir in the catchment of the River Tywi of Central Wales. These demonstrated a clear correspondence between the biological quality and fisheries of streams in the catchment and aspects of stream chemistry, par ticularly pH, aluminium and calcium on the one hand, and catchment land use on the other. It is salutary to record that the first signals were of an inexplicable failure of the runs of migratory salmonids into the upper catchment, occupied by the Llyn Brianne reservoir and its influent streams, and the failure to restore the fishery by re-stocking with eggs and fry. Only then did the significance of the recent decline in some other upland lake and reservoir fisheries in Wales become apparent.

"Situated on the western margin of Europe, Wales has been moulded by the erosional and depositional power of its fresh waters by virtue of high rainfall interacting with extensive regions of bedrock and post- Ice Age glacial debris. The result is a still evolving landscape rich in upland bogs, springs, mountain streams and lakes, rivers running through deeply eroded valleys, and large, lowland rivers meandering across wide floodplains into estuaries and the sea. Subsequent chapters bring together, for the first time, the combined expertise of a group of scientists whose intimate and collective knowledge of the Welsh aquatic landscape is unparalleled. The authors begin by describing the knowledge base of these important habitats, emphasising the structure and role of their plant, animal, and microbial communities. Upon this are built chapters that review the pioneering role of Welsh river studies in the development of running water science and, very poignantly, assess the high degree of human alteration of the principality's riverine ecosystems. These are followed by chapters that discuss the need for further scientific study, management, conservation, restoration and education so that future impacts on Welsh waters may be understood and minimised. Throughout the book flows the underlying theme that there has been and always will be a close link between water resources and the development of Welsh society."--Publisher's description.
